Description

A camera parameter configuration method and electronic equipment

technical field

The present application relates to the technical field of terminals, and in particular to a camera parameter configuration method and electronic equipment.

Background technique

The photographing function has become a basic function of most electronic devices (eg, mobile phones). With the popularization of shooting functions in electronic devices, users have higher and higher requirements for shooting quality of electronic devices. For electronic devices, instructing the camera sensor in the electronic device to enable an adapted image output mode in different shooting scenarios can effectively improve the shooting quality of the electronic device. For example, in normal scenes, enable the Binning image output mode; in high dynamic scenes, enable the intra-scene dual conversion gain (Idcg) image output mode; in the scene where the user instructs to zoom in on the shooting screen, enable Remosaic image output model.

In related technologies, before the camera sensor starts streaming, it is necessary to write repeated data to the camera sensor multiple times, so that the camera sensor can switch between multiple image output modes under the condition of uninterrupted streaming. Obviously, this also increases the boot time of the camera sensor.

Contents of the invention

Embodiments of the present application provide a method for configuring camera parameters and an electronic device, which shorten the start-up time consumption of the camera sensor while ensuring the switching of multiple output modes.

In order to achieve the above object, the embodiments of the present application adopt the following technical solutions:

In the first aspect, an embodiment of the present application provides a camera parameter configuration method, the method includes: instructing the first camera sensor to configure the first configuration parameter, the first configuration parameter is a camera shared between multiple drawing modes Parameters, the multiple drawing modes include a first drawing mode and a second drawing mode; instruct the first camera sensor to configure a first data package, and the first data package includes a second configuration parameter and a third configuration parameter, the second configuration parameter corresponds to a first identifier, and the first identifier instructs the first camera sensor to load the first image corresponding to the first drawing mode after receiving the first data packet. Two configuration parameters.

Wherein, the above-mentioned first configuration parameter and the second configuration parameter constitute camera parameters required for enabling the first drawing mode, which may also be referred to as camera parameters. The above-mentioned first configuration parameters and third configuration parameters constitute all camera parameters required for enabling the first drawing mode, which may also be referred to as camera parameters.

Exemplarily, the foregoing instructing the first camera sensor to configure the first configuration parameter may be: writing the first configuration parameter into the first camera sensor, and then loading it by the first camera sensor. For example, after the first configuration parameter is encapsulated according to the I2C protocol, the camera driver sends the package to the first camera sensor, and the first camera sensor can directly load the first configuration parameter after receiving it.

Exemplarily, the above-mentioned instructing the first camera sensor to configure the first data packet may be: writing the first data packet into the first camera sensor, for example, after encapsulating the first data packet according to the I2C protocol, the camera driver sends the first data packet to the first camera sensor. Then, the first camera sensor is triggered to load the second configuration parameters in the first data packet through the first flag in the first data packet.

It can be understood that after the first camera sensor is loaded with the first configuration parameters, the basic functions of the camera sensor can be executed. For example, the above-mentioned first configuration parameter may include a public parameter indicating that the camera sensor recognizes the default identifier (eg, the first identifier) in the FMC data packet (eg, the first data packet), and may include indicating that the camera sensor receives the After the first data packet, the public parameters of the configuration parameters corresponding to the default identifier are loaded.

In this way, after writing the first data packet to the first camera sensor, there is no need to repeatedly write the second configuration parameters to the first camera sensor, and the first camera sensor can automatically identify and load the configuration parameters of multiple drawing modes. The second configuration parameter corresponding to the first image output mode enables the first camera sensor to output an image in the first image output mode, completing the activation of the first camera sensor.

In the above embodiment, the configuration parameters of multiple drawing modes in the first data packet provide conditions for fast switching between multiple drawing modes. In addition, the first identifier in the first data packet solves the problem that the first camera sensor cannot directly load the configuration parameters of a certain image output mode in the first data packet. In this way, after the first data packet is written into the first camera sensor, the first camera sensor can also be triggered to load the second configuration parameter without repeatedly writing the second configuration parameter into the first camera sensor.

In short, on the premise of ensuring the rapid switching between multiple image output modes, the steps of writing repeated data to the first camera sensor are reduced, and the amount of data written to the first camera sensor is also reduced, effectively shortening the first Camera parameter configuration time for camera sensor.

In some embodiments, before instructing the first camera sensor to configure the first configuration parameter, the method includes: detecting a first operation of the user indicating to open the first application; in response to the first operation, displaying the first interface, The first interface is a first-type preview interface provided by the first application; after instructing the first camera sensor to configure the first data package, the method further includes: in response to loading the second configuration parameter, at the A first image frame is displayed on an interface, and the first image frame is an image obtained by the first camera sensor using the first drawing mode.

Wherein, the above-mentioned first application may be a camera application, or other application programs with a shooting function. The first application can display different types of preview interfaces when different camera modes are enabled.

In the above embodiment, when the user opens the first application, the electronic device can shorten the start-up time of the first camera sensor while ensuring fast switching among multiple output modes.

In some embodiments, the multiple drawing modes further include a third drawing mode, and the first data packet further includes a fourth configuration parameter corresponding to the third drawing mode, and the fourth configuration parameter Among the camera parameters used to start the third image output mode, parameters other than the first configuration parameters, the method further includes: under the first condition, writing first information to the first camera sensor , the first information indicates that the first camera sensor loads a third configuration parameter from the first data packet, and the data volume of the first information is smaller than the data volume of the third configuration parameter; in response to the Loading a third configuration parameter, displaying a second image frame in the first interface, the second image frame is an image obtained by the first camera sensor using the second drawing mode; under the second condition, Writing second information to the first camera sensor, the second information instructs the first camera sensor to load fourth configuration parameters from the first data packet, and the data volume of the second information is smaller than the The data volume of the fourth configuration parameter; in response to the loading of the fourth configuration parameter, displaying a third image frame in the first interface, the third image frame is the first camera sensor using the third output An image obtained in the drawing mode; wherein, the first condition indicates a scene suitable for enabling the second drawing mode; the second condition indicates a scene suitable for using the third drawing mode.

In the above embodiments, when the shooting scene changes, the electronic device only needs to write the first information or the second information to the first camera sensor, and then it can quickly switch between different image output modes. Compared with the configuration parameters (third configuration parameters or fourth configuration parameters) of the drawing mode (the second drawing mode or the third drawing mode), the above-mentioned first information or second information has a smaller data size, and it is written in the first The speed of the camera sensor is faster, and the switching speed of the trigger drawing mode is faster.

In some embodiments, when the second image output mode is the Idcg image output mode, the first condition includes: when the zoom ratio of the camera corresponding to the first camera sensor belongs to the first interval, it is detected that The first brightness of the first light is greater than the first threshold, and the high dynamic range HDR flag indicates that HDR has been turned on; when the third drawing mode is the Remosaic drawing mode, the second condition includes that the first camera sensor The zoom ratio of the corresponding camera belongs to the second interval, and the detected first quantized illumination value is smaller than the second threshold, and the value in the first interval is smaller than the value in the second interval.

In the above embodiment, under different zoom ratios and different conditions, the shooting scene is identified, and the image output mode to be used is determined to ensure that the enabled image output mode is adapted to the shooting scene, and the shooting quality is improved.

In some embodiments, after displaying the second image frame or the third image frame, the method further includes: under a third condition, writing third information to the first camera sensor, the The third information indicates that the second configuration parameter is loaded from the first data packet; in response to the loading of the second configuration parameter, in the first interface, a fourth image frame is displayed, and the fourth image frame is the image obtained by the first camera sensor using the first drawing mode; the third condition includes any one of the following: when the zoom ratio of the camera belongs to the first interval, the detected second The light brightness is not greater than the first threshold, or the HDR flag indicates that HDR has been turned off; when the zoom ratio of the camera belongs to the second interval, the detected second illuminance quantification value is not less than the first Two thresholds.

In the above embodiment, the electronic device can also accurately identify the scene switched back to the first image output mode at different zoom ratios, so as to improve the accuracy of switching the image output mode and improve the shooting quality.

In some embodiments, the method further includes: in response to the second operation, displaying a second interface, the second interface is a second-type preview interface provided by the first application; instructing the first camera sensor to configure the second interface; A data packet, the second data packet includes a fifth configuration parameter, and the fifth configuration parameter includes parameters other than the first configuration parameter in the camera parameters for enabling the fourth drawing mode; the fifth configuration The parameter corresponds to a second identifier, and the second identifier may be a default identifier in the second data packet. The second identification indicates that after the first camera sensor receives the second data packet, the fifth configuration parameter is loaded; in response to loading the fifth configuration parameter, a fifth image frame is displayed on the second interface , the fifth image frame is an image obtained by the first camera sensor using the fourth image output mode.

It can be understood that when the first application is switched to enable different camera modes, the displayed preview interface types are different, and the above-mentioned first interface and second interface are preview interfaces displayed when different camera modes are enabled. The electronic device switches from displaying the first interface to displaying the second interface in response to the second operation, essentially switching from one camera mode to another camera mode in response to the second operation.

In the above embodiment, after the camera mode is switched, there is no need to configure the first configuration parameter again, so that the switching speed between camera modes is accelerated.

In some embodiments, before instructing the first camera sensor to configure the second data packet, the method includes: determining the camera sensors that can be enabled during the display of the second interface and the camera sensors that can be enabled during the display of the first interface same.

It can be understood that, when the camera sensors that can be activated during the display of the second interface are the same as the camera sensors that can be activated during the display of the first interface, the camera sensors that are actually displayed during the display of the second interface are the same as those actually displayed during the display of the first interface. The camera sensors for display can be the same, so that even if the camera mode is switched and the first configuration parameters are not delivered, the camera sensors can still be used normally.

In the above embodiment, after it is determined that the enableable camera sensors are the same before and after switching the preview interface, it is determined not to rewrite the first configuration parameter to the camera sensor. Under the premise of ensuring that the camera sensor can work normally, reduce the amount of data written to the camera sensor.

In some embodiments, the method further includes: in response to the third operation, displaying a third interface, where the third interface is a third-type preview interface provided by the first application; wherein, displaying the third interface The camera sensors that can be enabled during the period are different from the camera sensors that can be enabled during the display of the first interface; instruct the second camera sensor to configure the first configuration parameters, instruct the second camera sensor to configure the third data package, and the third data package Including a sixth configuration parameter, the sixth configuration parameter includes parameters other than the first configuration parameter in the camera parameters for enabling the fifth drawing mode; the sixth configuration parameter corresponds to a third identifier, and the The third identification indicates that after the second camera sensor receives the third data packet, the sixth configuration parameter is loaded; in response to loading the sixth configuration parameter, a sixth image frame is displayed on the third interface , the sixth image frame is an image obtained by the second camera sensor using the fifth image output mode.

In the above embodiment, after it is determined that the camera sensors that can be enabled are different before and after switching the preview interface, it is determined to rewrite the first configuration parameter to the camera sensor to ensure that the camera sensor can be displayed normally.

Detailed ways

Hereinafter, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

The implementation of this embodiment will be described in detail below in conjunction with the accompanying drawings.

An embodiment of the present application provides a method for configuring camera parameters, which is applied to an electronic device with a shooting function.

Exemplary, the electronic device may be a desktop, laptop, tablet, handheld computer, cell phone, notebook computer, Ultra-mobile Personal Computer (UMPC), netbook, as well as a cellular phone, personal digital assistant ( Personal Digital Assistant, PDA), television, VR equipment, AR equipment and other equipment with cameras.

As shown in FIG. 1 , the electronic device 100 can be divided into an application layer (referred to as the application layer), an application framework layer (referred to as the framework layer), a hardware abstraction layer (hardware abstraction layer, HAL), and a kernel (Kernel) layer from top to bottom. (also known as the driver layer) and several layers such as the hardware (Hardwork) layer, each layer has a clear role and division of labor. Layers communicate through software interfaces.

It can be understood that Fig. 1 is only an example, that is, the layers divided in the electronic device are not limited to the layers shown in Fig. 1, for example, between the application framework layer and the HAL layer, Android runtime (Android runtime ) and system libraries (libraries) layer, etc.

Exemplarily, the application layer may include a series of application program packages. As shown in FIG. 1, the application layer may include a camera application. Of course, in addition to the camera application, the application layer may also include other application packages, such as multiple application packages such as a gallery application and a video application.

Generally speaking, the application program is developed using the Java language, and is completed by calling an application programming interface (application programming interface, API) and a programming framework provided by the application program framework layer. Exemplarily, the application framework layer includes some predefined functions.

As shown in FIG. 1 , the application framework layer may include a camera service, which can be invoked by the camera application, so as to realize shooting-related functions. Of course, the application framework layer can also include content provider, resource manager, notification manager, window manager, view system, phone manager, etc. Similarly, the camera application can also call content provider, resource Manager, notification manager, window manager, view system, etc., are not limited in this embodiment of the present application.

The aforementioned kernel layer is a layer between hardware and software. As shown in Figure 1, the kernel layer contains at least a camera driver. The camera driver can be used to drive hardware modules with shooting functions, such as camera sensors. In other words, the camera driver mentioned above is responsible for data interaction with the camera sensor. Certainly, the kernel layer may also include driver software such as an audio driver program and a sensor driver program, which is not limited in this embodiment of the present application.

In addition, the HAL layer can encapsulate the driver program in the kernel layer, and provide the calling interface to the application framework layer, shielding the implementation details of the low-level hardware.

As shown in FIG. 1 , the above HAL layer may include a camera (Camera) HAL, a decision module and XML.

Wherein, the Camera HAL is the core software framework of the Camera, and the Camera HAL includes a sensor node (Sensor node), an image processing module, an interface module, and the like. Among them, the above-mentioned Sensor node, image processing module and interface module are the components in the image data and control command transmission pipeline in Camera HAL, of course, different components also have different functions. For example, the Sensor node may be a control node for a camera sensor, and the Sensor node may control the camera sensor through a camera driver. For another example, the interface module can be a software interface oriented to the application framework layer for data interaction with the application framework layer. Of course, the interface module can also interact with other modules in the HAL (eg, decision-making module, image processing module, Sensor node) For data interaction. For another example, the image processing module may process the original image data sent back by the camera sensor. Exemplarily, the above image processing module may include an image front end (IFE) node (IFE node) and a Bayer processing (bayer processing segment, BPS) node (BPS node), wherein, the IFE is used to process the preview stream collected by the camera sensor, and the BPS node is used to process the photo stream collected by the camera sensor. In addition, the image processing module may also include nodes with other image processing capabilities. For details, reference may be made to related technologies, which will not be repeated here.

In addition, the above-mentioned decision-making module is a multi-camera decision-making module under the CamX-Chi architecture. This decision-making module can determine the actual camera sensor (such as the front camera sensor, rear camera sensor, etc.) The drawing mode of . For the image output mode of the camera sensor, refer to the detailed description in the subsequent embodiments.

In addition, the aforementioned XML can be used to transmit and store data. Exemplarily, the above XML can obtain various configuration parameters from the memory of the electronic device, for example, the configuration parameters required for the operation of the camera sensor. At the same time, XML can also support the Sensor node to query the stored configuration parameters.

In addition, FIG. 1 also exemplarily shows hardware modules that can be driven in the hardware layer, such as target camera sensors and the like. Of course, hardware modules not shown in FIG. 1 may also be included in the hardware layer, such as a camera, a processor, a memory, etc., or other camera sensors except the target camera sensor.

As mentioned above, the camera sensor can support multiple image output modes, such as Binning image output mode, Idcg image output mode and Remosaic image output mode.

Among them, in the binning image output mode, after the camera sensor collects the original pixel array, the induced charges corresponding to adjacent pixels in the original pixel array are added together as an actual output pixel point. The binning image output mode uses several adjacent pixels together as one pixel. In this way, the original image data output from the camera sensor to the camera driver maintains the same field of view (FOV) compared to the original pixel array. At the same time, the output resolution is reduced, the photosensitive area is increased, and the sensitivity to light sensing in dark places is improved. Usually, Binning output mode is also the default output mode.

In addition, in the Idcg image output mode, the dynamic range of the camera sensor can be improved. The dynamic range is the ability of the camera sensor to simultaneously reflect the content of highlights and shadows in an image. Wherein, the greater the dynamic range of the camera sensor, the stronger the ability of the camera sensor to reflect the contents of highlights and shadows. In the Idcg image output mode, the camera sensor uses the same exposure time to simultaneously acquire the high conversion gain (HCG) map and the low conversion gain (LCG) map corresponding to the same frame of raw image data. Then, the camera sensor fuses the high-gain image and the low-gain image into one frame of image, which is used as the original image data actually output to the camera driver.

Compared with the binning drawing mode, the above-mentioned Idcg drawing mode has a larger dynamic range. Of course, the corresponding power consumption is also higher, which is about 1.5 times that of the binning drawing mode.

In the Remosaic image output mode, the camera sensor uses the original pixel array collected by the 4-cell sensor as the original image data output to the camera driver, that is, in the Remosaic image output mode, the original image data received by the camera driver is Synthesized without binning pixels. That is, when the Remosaic output mode is enabled, the raw image data obtained by the camera driver cannot be directly recognized and processed. The original image data needs to be converted into a standard bayer format image, and this conversion process is called remosaic. Exemplarily, the original image data received by the camera driver may be converted into remosaic image data by an image processing module in the Camera HAL. Compared with the original image data obtained in the binning image output mode, the above remosaic image data has more pixels and higher definition, and is more suitable for the shooting scene where the user instructs to enlarge the shooting image (that is, increase the zoom ratio).

Each of the above-mentioned output modes has different advantages and is also applicable to different scenarios. For example, the Binning image output mode is suitable for conventional shooting scenes. For example, the Idcg image output mode is suitable for backlit or high-brightness shooting scenes. For example, the Remosaic image output mode is suitable for shooting scenes where the user instructs to increase the zoom ratio.

In some embodiments, during the shooting process, the electronic device may dynamically instruct the target camera sensor to switch between different image output modes according to the real-time shooting scene. Wherein, the aforementioned target camera sensor refers to the camera sensor currently collecting and displaying data. In this way, the electronic device can capture high-quality image data (eg, photos, videos) in different shooting scenarios.

It can be understood that the electronic device switching between different image output modes means that the target camera sensor switches between different image output modes. When the target camera sensor switches between different output modes, the mode parameters that need to be loaded may be different.

Exemplarily, the above-mentioned mode parameters may include an angle of view, an output image size, an output image aspect ratio, a frame rate, and other parameters. Wherein, above-mentioned other parameters can comprise: color, data transmission rate, exposure parameter, one frame data line number (FrameLength Lines), and this Frame Length Lines comprises field blanking, one line of data pixel points (Line LengthPCK), and this Line Length PCK comprises Line blanking, clipping parameters, scaling parameters, clock frequency, data transmission rate, phase focus parameters, pixel binning method, internal timing, effect processing related parameters and DCG related parameters (such as internal gain ratio of LCG and HCG, LCG and HCG image fusion algorithm parameters, etc.) etc. one or more.

In addition, in different camera modes, the electronic device instructs the target camera sensor to adopt the same type of drawing mode, and the mode parameters required to be configured by the target camera sensor may be different parameters. Wherein, the camera mode may include a photographing mode, a video recording mode (or a high dynamic video recording mode), a portrait mode, a 4K dynamic frame rate mode, and the like. Among them, the camera mode refers to the functional mode for taking photos, the video recording mode refers to the functional mode for shooting videos, the portrait mode refers to the functional mode for shooting people, and the 4K dynamic frame rate mode refers to the functional mode for shooting 4K dynamic Functional mode of frame rate video, the 4k dynamic frame rate video can be video data with a resolution of 4k and a dynamically changing frame rate. The camera application enables different camera modes to display different shooting interfaces.

Taking the camera sensor whose target camera sensor is the main camera as an example, in each camera mode, the image output modes that can be enabled and the corresponding mode parameters are shown in Table 1 below:

Table 1

Among them, the mode parameter (mode setting) corresponding to the Binning drawing mode can be called the Binning mode parameter; the mode parameter (mode setting) corresponding to the Idcg drawing mode can be called the Idcg mode parameter; the mode parameter corresponding to the Remosaic drawing mode (mode setting), which can be called the Remosaic mode parameter.

It can be seen from Table 1 that the Binning image output mode may include: a Binning image output mode with an image color number of 14 bits, and a Binning image output mode with a color number of 10 bits. The image output modes with different numbers of colors may have different image output quality. Of course, in the embodiment of practical application, it can also include the Binning output mode with other sizes of color numbers, and can also configure different viewing angles, different output sizes, different output aspect ratios, different frame rates and/or Or the Binning output mode with different other parameters (zoom parameters).

In some embodiments, when the Binning image output mode is enabled in different camera modes of the electronic device, there may be differences in the Binning mode parameters actually loaded by the target camera sensor, so as to adapt to different camera modes. In the Binning image output mode, the image output effect different requirements.

In other possible embodiments, when the binning mode is enabled in different camera modes of the electronic device, the binning mode parameters actually loaded by the target camera sensor may also be the same, which is not specifically limited in this embodiment of the present application.

Similarly, the Remosaic image output mode may also include: a Remosaic image output mode with an image color number of 14 bits, and a Remosaic image output mode with a color number of 10 bits. The image output modes with different numbers of colors may have different image output quality. Of course, in the embodiment of practical application, it can also include the Remosaic image output mode with the number of colors in other sizes, and can also configure different viewing angles, different image output sizes, different image output aspect ratios and/or different frame rates Remosaic drawing mode.

In some embodiments, when the electronic device enables the Remosaic drawing mode in different camera modes, the Remosaic mode parameters actually loaded by the target camera sensor may be different, so as to adapt to different camera modes. Different requirements.

Of course, in other embodiments, when the Remosaic drawing mode is enabled in different camera modes, the Remosaic mode parameters actually loaded by the target camera sensor may also be the same, which is not specifically limited in this embodiment of the present application.

Similarly, the Idcg image output mode may also include: an Idcg image output mode with an image color number of 14 bits, and an Idcg image output mode with a color number of 10 bits. The image output modes with different numbers of colors may have different image output quality. Certainly, in the embodiment of the actual application, it may also include the Idcg image output mode with the number of colors of other sizes, and it may also be configured with different viewing angles, different image output sizes, different image output aspect ratios, different frame rates and/or Or Idcg drawing mode with different DCG parameters.

In some embodiments, when the electronic device is in different camera modes, when the Idcg drawing mode is enabled, the Idcg mode parameters actually loaded by the target camera sensor may be different, so as to adapt to different camera modes. In the Idcg drawing mode, the effect of drawing Different requirements.

Of course, in other embodiments, when the Idcg output mode is enabled in different camera modes, the Idcg mode parameters actually loaded by the target camera sensor may also be the same, which is not specifically limited in this embodiment of the present application.

In addition, as shown in Table 1, in the same camera mode, there are the same parameters in Binning mode parameters, Idcg mode parameters and Remosaic mode parameters, such as field of view, output image size, output image aspect ratio and frame rate. In this way, in the same camera mode, the continuity of the preview screen will not be affected when switching between Binning output mode, Idcg output mode and Remosaic output mode.

Of course, there are still different parameters among the Binning mode parameters, the Idcg mode parameters and the Remosaic mode parameters. For example, Binning mode parameters include scaling parameters, while Remosaic mode parameters do not include scaling parameters. For another example, the value of the clipping parameter of the Binning mode parameter is different from that of the Remosaic mode parameter. For another example, the Idcg mode parameters include DCG-related parameters, but neither the Binning mode parameters nor the Remosaic mode parameters include DCG-related parameters. For another example, the internal timing of the Binning mode parameter and the Remosaic mode parameter both indicate that the original image of the same frame only outputs the LCG image (or HCG image), and the internal timing of the Idcg mode parameter indicates that the original image of the same frame can output the LCG image and the HCG image synchronously.

In addition, the image output modes corresponding to each camera mode shown in Table 1 are only examples, and it can be understood that each camera mode may correspond to more or fewer image output modes. For example, in addition to the Binning image output mode and Idcg image output mode corresponding to the video recording mode, it can also correspond to the Remosaic image output mode. For another example, the video recording mode can only correspond to the binning output mode.

In the case that the electronic device includes multiple cameras, the target camera sensor may change during the operation of the electronic device, for example, the camera sensor of the main camera becomes the camera sensor of the telephoto camera (TELE camera). Even if the same output mode is enabled in the same camera mode, the mode parameters that need to be loaded for different target camera sensors may be different. For example, after the electronic device responds to the user's operation and turns on the camera mode, if it is determined that the main camera needs to enable the Binning image output mode, the electronic device may configure the Binning mode parameter a for the camera sensor corresponding to the main camera. Afterwards, the electronic device responds to the user's operation, and switches the display from the TELE camera. In this scenario, it is determined that the binning output mode needs to be enabled for the telephoto camera (TELE camera), and the electronic device can configure the Binning mode parameter b for the camera sensor corresponding to the TELE camera, and the Binning mode parameter a and the Binning mode parameter b can be different parameters .

An exemplary scenario, as shown in Figure 1, the camera application can pass information such as the camera mode and zoom ratio selected by the user to the camera service of the application framework layer, and then the camera service passes it to the decision-making module through the interface module of the HAL layer. In this way, the decision-making module can determine the output mode suitable for the current shooting scene according to the camera mode, zoom ratio and the recognized lighting environment, and notify the Sensor node.

In this way, the Sensor node can obtain the camera parameters matching the image output mode from XML, and the camera parameters include the mode parameters corresponding to the above image output mode (eg, binning mode parameters, Idcg mode parameters or Remosaic mode parameters).

Then, configure the corresponding camera parameters for the target camera sensor through the camera driver. For example, the Sensor node instructs the camera driver to interact with the I2C interface of the target camera sensor, writes the camera parameters to the target camera sensor, and instructs the target camera sensor to load.

In this way, as shown in Figure 2, after the target camera sensor loads the camera parameters, the target camera sensor sends the original image data to the camera driver according to the output mode corresponding to the camera parameters, for example, through the MIPI interface of the target camera sensor to the machine driver Send raw image data. Afterwards, the camera driver sends the original image data to the image processing module, and the original image data is processed by the image processing module to obtain image frames. It can be understood that when the camera application is in the shooting preview stage, the obtained image frames may also be called preview frames, and when the camera application is in the actual shooting stage, the obtained image frames may also be called camera frames. The image processing module can send the image frame to the camera application through the interface module and the camera service, so that the electronic device can display the image frame.

It can be understood that the process of actually configuring the image output mode corresponding to the target camera sensor by the electronic device is more complicated than the process described above. The above mode parameters may also be referred to as mode setting. In addition to the mode parameters, the above camera parameters may also include public parameters. In this way, the process of configuring camera parameters not only includes configuring mode parameters, but also includes configuring public parameters.

Wherein, the above public parameters may also be referred to as init setting, or init initialization parameters, which are parameters used to implement camera sensor initialization. For example, the above public parameters may include data transmission protocol, internal timing and interrupt frequency, etc. The above configuration public parameters may be public parameters instructing the target camera sensor to load. The above public parameters are the common parameters among the camera parameters that realize all image output modes supported by the electronic device. After the target camera sensor is loaded with the public parameters, it has basic operation capability.

The implementation details of the camera parameter configuration method provided by the embodiment of the present application will be described below with reference to the accompanying drawings, taking the electronic device as a mobile phone as an example.

In some embodiments, after the mobile phone activates an application program (such as a camera application) with a shooting function, it can configure camera parameters.

As shown in FIG. 3 , after the mobile phone is unlocked, a main interface 301 may be displayed. The main interface 301 includes an application icon 302 of the camera application. In a scenario where the background applications of the mobile phone do not include the camera application, the mobile phone may activate the camera application after the user's click operation on the application icon 302 is detected. For example, in response to the user's operation on the application icon 302, the mobile phone may display a waiting interface provided by the camera application, such as the interface 303. The interface 303 may be an application interface corresponding to the photographing mode. When the interface 303 is displayed, the camera sensor has not sent back the original image data, that is, there is no displayable image frame in the interface 303 .

In other embodiments, in the scenario where the camera application is included in the background application of the mobile phone, if the video recording mode is enabled before the camera application enters the background operation, the mobile phone may also display the waiting interface after receiving the user's click operation on the application icon 302 , the waiting interface is the application interface corresponding to the recording mode. In other possible embodiments, while the mobile phone is displaying the main interface 301 , a user's long press operation on the application icon 302 may be received. In this way, the mobile phone can display a mode selection window relative to the application icon 302, and the mode selection window includes mode controls indicating various camera modes. In this scenario, the mobile phone can receive the user's operation on any mode control and determine the camera mode selected by the user. For example, the mobile phone may display a waiting interface corresponding to the recording mode after receiving the user's operation on the mode control indicating the recording mode. In addition, in addition to clicking the application icon 302, in the scenario where the background applications of the mobile phone include the camera application, the mobile phone may be instructed to display the above-mentioned waiting interface by operating the multitasking interface. Of course, when the background application of the mobile phone does not include the camera application, the mobile phone can also be instructed to display the waiting interface corresponding to the default camera mode by operating the camera shortcut key. In addition, it is also possible to analyze whether it is necessary to open the camera application by recognizing the voice instructions spoken by the user, or by detecting gestures made by the user. For example, if it is recognized that the user speaks keywords such as "camera" and "shooting", it may be determined that the camera application needs to be opened, and a corresponding waiting interface is displayed. For another example, when it is recognized that the user makes a gesture action associated with the camera application, it may also be determined that the camera application needs to be opened, and a corresponding waiting interface is displayed. In addition, the gesture actions associated with the camera application can be preset.

In some embodiments, the mobile phone may configure camera parameters during the display of the waiting interface, so as to instruct the camera sensor to start collecting raw image data. In some embodiments, as shown in FIG. 4, the above method for configuring camera parameters may include:

S101, the mobile phone detects an operation indicating to start a camera application.

In some embodiments, the above operation may be a user's click operation on the camera icon.

In some other embodiments, the above operation may also be a user's long press operation on the camera icon. Certainly, the mobile phone may also display a mode selection window upon receiving the user's long press operation on the camera icon. The mode selection window includes mode controls that indicate the various camera modes. After the camera application determines that the user selects the mode control of any camera mode, the process may also enter S102.

It can be understood that the above S101 is only an example. During actual use, the mobile phone may also instruct the process to enter S102 according to other operations of the user. For example, the user operates window 1 in the multitasking interface, where a thumbnail image of the application interface of the camera application is displayed in the window 1 . For another example, the user clicks the shortcut entry of the camera application (for example, the camera shortcut entry displayed on the negative screen of the mobile phone). For another example, the mobile phone detects that the user speaks a keyword related to the camera application, or detects that the user makes a gesture action related to the camera application, etc., may also indicate that the process can enter S102.

S102, the mobile phone controls the camera sensor 1 to be powered on, and the camera sensor 1 includes a target camera sensor.

Wherein, the aforementioned camera sensor 1 may also be a camera sensor corresponding to camera mode 1 . In addition, camera mode 1 is the camera mode that the camera application recognizes and needs to enable currently.

Exemplarily, when the camera application is not running in the background of the mobile phone, after the mobile phone starts the camera application, the camera application can determine that the default camera mode needs to be enabled (for example, the default camera mode can be pre-configured as the camera mode), so that the camera mode 1 is Default camera mode.

Also exemplary, there is a camera application running in the background of the mobile phone, and the camera application determines that the camera mode used last time needs to be enabled, for example, the camera mode before the camera application enters the background operation. In this way, camera mode 1 is the last enabled camera mode for the camera application.

In a scenario where the mobile phone starts the camera application in response to the operation of the camera mode selected by the user, the camera application may determine that the selected camera mode needs to be activated currently. In this way, camera mode 1 is the camera mode selected by the user.

Understandably, when the mobile phone is equipped with multiple cameras, different cameras can be used in different camera modes when the camera is applied. For example, a mobile phone includes a front camera 1 , a front camera 2 , a rear camera 1 , a rear camera 2 and a rear camera 3 . In the camera mode, the available cameras are the front camera 1, rear camera 1, rear camera 2 and rear camera 3 of the mobile phone. In portrait mode, the available cameras are the front camera 1, front camera 2 and rear camera 1 of the mobile phone.

In this way, when it is determined that the camera mode 1 is the photographing mode, the camera sensor 1 includes camera sensors corresponding to the front camera 1 , the rear camera 1 , the rear camera 2 and the rear camera 3 . In this scenario, the mobile phone responds to the above instructions to start the operation of the camera application, and controls the camera sensors corresponding to the front camera 1, the rear camera 1, the rear camera 2, and the rear camera 3 to be powered on.

When it is determined that the camera mode 1 is a portrait mode, the camera sensor 1 includes camera sensors corresponding to the front camera 1 , the front camera 2 and the rear camera 1 . In this scenario, the mobile phone responds to the above instructions to start the operation of the camera application, and controls the camera sensors corresponding to the front camera 1, the front camera 2, and the rear camera 1 to be powered on.

Of course, in some other embodiments, the above-mentioned camera sensor 1 may be all camera sensors configured in the mobile phone. In this way, the mobile phone can control all camera sensors of the mobile phone to be powered on in response to the operation of starting the camera application in response to the above instructions, which is not specifically limited in this embodiment itself.

In some embodiments, after the mobile phone detects an operation (such as the first operation) indicating to start the camera application (such as the first application), it may also display the first type of preview interface provided by the camera application, that is, the first interface . The first type of preview interface may be an image preview interface displayed during camera mode 1 operation. For example, camera mode 1 is a photographing mode, and the above-mentioned first type of preview interface may be a photographing preview interface, such as interface 303 in FIG. 3 . The camera mode 1 is a portrait mode, and the above-mentioned first type of preview interface may be a portrait preview interface (also called a portrait shooting interface). Camera mode 1 is a video recording mode, and the above-mentioned first type of preview interface may be a video recording preview interface (also called a video recording interface). In addition, during the display of the first interface, the target camera sensor corresponding to the mobile phone may be the first camera sensor.

S103, the mobile phone instructs the camera sensor 1 to configure public parameters.

In some embodiments, the above-mentioned public parameters can also be referred to as first configuration parameters, and the mobile phone can write the public parameters into each camera sensor 1 in turn, and then instruct the camera sensor 1 to load the public parameters. By loading public parameters, the camera sensor 1 has the ability to perform basic functions.

When the mobile phone displays the first interface, that is, when the camera mode 1 is enabled, the camera sensor 1 includes the first camera sensor as the target camera sensor.

In some embodiments, after each camera sensor 1 writes the public parameters, the mode record function can be called, such as, setstaticlastresindex(cameraID, resindex), and record the camera ID (cameraID) of the camera sensor 1 in a specific storage location 1 ) and the current drawing mode identification (resindex) of the camera sensor 1. It can be understood that the above camera identifier may uniquely indicate the corresponding camera sensor 1 . In addition, the image output mode identifier may indicate the image output mode currently enabled by the camera sensor 1 . At the stage of configuring the public parameters, the camera sensor 1 has not enabled any image output mode, so the recorded image output mode identifier can be a serial number indicating initialization, for example, the serial number indicating initialization is 255.

Taking the camera sensor 1 with cameraID as 1 as an example, after writing the public parameters in the camera sensor 1, the mobile phone can record the cameraID "1" and the drawing mode identifier "255" in the storage location 1 through setstaticlastresindex(1, 255) "The corresponding relationship between. In this way, when the mobile phone accesses the storage location 1, it can be determined that the public parameter configuration of the camera sensor 1 has been completed according to the correspondence between the cameraID "1" and the drawing mode identifier "255".

S104. The mobile phone determines whether the current camera mode 1 corresponds to a fast mode change (FMC) data packet 1.

In some embodiments, a preset list may be pre-configured in the mobile phone, and the preset list records the image output modes that can be enabled by the camera application in each camera mode.

In the case that the camera mode can enable multiple image output modes, the camera mode can correspond to multiple sets of mode parameters, and each set of mode parameters corresponds to an image output mode. Each group of mode parameters contains a large number of attribute values required to realize the drawing mode, and the data volume is relatively large.

It can be understood that when this type of camera mode is enabled on the mobile phone, there is a business requirement for fast switching between image output modes, which can also be called a seamless business requirement. In this way, mode parameters corresponding to multiple drawing modes in this type of camera mode, that is, multiple sets of mode parameters can be encapsulated in the same data package, and the data package can also be called an FMC data package. Of course, the FMC data packet also includes switch fields corresponding to different drawing modes. Wherein, the above switch field carries the value of a specific register in the camera sensor. Usually the switch field does not contain the attribute value to realize the corresponding drawing mode, and its data volume is much smaller than the mode parameter corresponding to the drawing mode.

In addition, when the specific registers of the camera sensor are loaded with different values, the camera sensor may be instructed to load mode parameters corresponding to different drawing modes from the FMC data packet. In this way, after the FMC data packet is written into the camera sensor, the camera sensor can be enabled to enable the target image output mode by instructing the camera sensor to load the switch field of the target image output mode pair. Wherein, the FMC data packet includes a mode parameter and a switch field corresponding to the target drawing mode. In the case that a camera mode can enable a drawing mode, the camera mode only corresponds to a set of mode parameters.

In some embodiments, the mobile phone can determine whether the camera mode 1 corresponds to the FMC data package 1 through the preset list. For example, in the case that the camera mode 1 corresponds to multiple output modes in the preset list, it is determined that the camera mode 1 corresponds to the FMC data package 1 . For example, in the scene where camera mode 1 is the camera mode, the camera mode corresponds to 14bit binning image output mode, 14bit Idcg image output mode and 14bit Remosaic image output mode in the preset list. In this way, it can be determined that the camera mode corresponds to FMC data Bag.

For another example, the preset list also includes a dedicated configuration parameter identifier corresponding to each camera mode, and the dedicated configuration parameter identifier may indicate a dedicated configuration parameter type (eg, FMC data packet or mode parameter) corresponding to the camera mode. If camera mode 1 corresponds to multiple output modes, the exclusive configuration parameter identifier of camera mode 1 in the preset list can be the identifier "FMC data package 1", indicating that the exclusive configuration parameter type corresponding to camera mode 1 is FMC data package , so that it can be determined that camera mode 1 corresponds to FMC data packet 1. If the camera mode 1 corresponds to only one output mode, the exclusive configuration parameter identifier of the camera mode 1 in the preset list may be the identifier "mode parameter 1", indicating that the exclusive configuration parameter type corresponding to the camera mode 1 is a mode parameter. In this way, It can be determined that the camera mode 1 does not correspond to the FMC data packet, and only corresponds to the mode parameter 1.

In some embodiments, the above-mentioned FMC data packet 1 may be referred to as the first data packet. The first data packet includes a plurality of configuration parameters (also referred to as mode parameters) of drawing modes.

In the case that multiple output modes include the first output mode and the second output mode, the first data packet includes the mode parameters corresponding to the first output mode (that is, the second configuration parameters) and the second output mode. The mode parameter (that is, the third configuration parameter) corresponding to the graph mode.

In the case that multiple output modes include the first output mode, the second output mode and the third output mode, the first data packet includes the mode parameters corresponding to the first output mode and the parameters corresponding to the second output mode. The mode parameter of and the mode parameter corresponding to the third drawing mode (that is, the fourth configuration parameter).

Wherein, the above-mentioned second configuration parameters may include camera parameters capable of realizing the first drawing mode, except the common parameters. The above-mentioned third configuration parameters may include camera parameters capable of realizing the second drawing mode, except the common parameters. The above-mentioned fourth configuration parameters may include camera parameters capable of realizing the third drawing mode, except the common parameters.

Exemplarily, the first graph output mode, the second graph output mode and the third graph output mode may be one of binning graph output mode, Idcg graph output mode and Remosaic graph output mode, and they are different from each other.

S105, in the case that the camera mode 1 corresponds to the FMC data package 1, the mobile phone instructs the target camera sensor to configure the FMC data package 1.

In some embodiments, the phone may write FMC packet 1 to the target camera sensor. Then, instruct the target camera sensor to load the specified mode parameters in FMC packet 1. Wherein, the specified mode parameter may be one group of multiple groups of mode parameters encapsulated in the FMC data packet 1 . The above-mentioned process of writing the FMC data packet 1 to the target camera sensor and loading the specified mode parameters to the target camera sensor can be referred to as configuring the FMC data packet 1.

Exemplarily, the above specified mode parameter may be a mode parameter corresponding to any drawing mode supported by camera mode 1. After the target camera sensor receives the FMC data packet 1, a set of mode parameters can be randomly loaded from the FMC data packet 1.

As another example, the above specified mode parameter may be a mode parameter corresponding to the default drawing mode of camera mode 1, such as called a default mode parameter. Wherein, the default image output mode of each camera mode may be a pre-selected image output mode among the image output modes supported by the camera mode. In this way, during the process of encapsulating the FMC data packet 1, the default mode parameter of the default drawing mode can be marked, or the switch field corresponding to the default drawing mode can be marked. For example, use the first identifier to identify the second configuration parameter in the FMC data package 1, so that the second configuration parameter is the default mode parameter in the FMC data package 1, and the first drawing mode is also the default drawing mode of the camera mode 1 .

After the target camera sensor loads the public parameters, it has the ability to identify the first identifier in the FMC data packet 1, so that when the default mode parameter is marked in the FMC data packet 1, the target camera sensor receives the FMC data packet 1 Afterwards, default mode parameters may be loaded according to the first identifier.

When the switch field corresponding to the default drawing mode is marked in the FMC data packet 1, after receiving the FMC data packet 1, the target camera sensor configures the value of a specific register according to the switch field of the default drawing mode. In this way, the target camera sensor can load default mode parameters from FMC packet 1 according to specific registers.

In the subsequent embodiments, the description is mainly made with the specified mode parameter being the default mode parameter.

In some other embodiments, before the target camera sensor loads the mode parameters from the FMC data packet 1, the mobile phone needs to determine the image output mode currently enabled by the target camera sensor. As an implementation manner, the mobile phone may use the function Updatelastresindex(cameraID) to query the latest image output mode identifier recorded by the target camera sensor from the storage location 1. For example, if the cameraID of the target camera sensor is "1", it can be determined by calling Updatelastresindex(1) to obtain the output mode identifier corresponding to the target camera sensor recorded last time.

It can be understood that the mobile phone can record the output mode corresponding to the camera sensor in the storage location 1 through setstaticlastresindex. Before S105, when the mobile phone called setstaticlastresindex last time to record the image output mode of the target camera sensor, the recorded image output mode identifier was a serial number indicating initialization (eg, 255). In this way, the mobile phone can obtain the map output mode identifier "255" through Updatelastresindex(1). In the case where the image output mode identifier is "255", the mobile phone may determine that the target camera sensor has not yet enabled any image output mode.

When it is determined that the target camera sensor has not enabled any drawing mode, the mobile phone instructs the target camera sensor to load the above specified mode parameters. In this way, the target camera sensor can start to enable the output mode corresponding to the specified mode parameter.

In some other embodiments, after the target camera sensor loads the mode parameters from the FMC data packet, the mobile phone can update the output mode corresponding to the cameraID (also called the target camera ID) of the target camera sensor in storage location 1 logo. The updated drawing mode identifier may indicate the drawing mode corresponding to the mode parameter loaded this time.

In some embodiments, the mobile phone may also pre-configure a serial number subscript for all image output modes, that is, an image output mode identifier. The graphic output mode identifiers corresponding to different graphic output modes may be stored in the mobile phone in the form of a list.

For example, the image output modes supported by the mobile phone are shown in Table 1, and correspondingly, the pre-configured image output mode identifiers can be shown in Table 2:

Table 2

As an implementation, after the target camera sensor loads the mode parameters from the FMC data packet, the mobile phone can update the target camera ID (that is, the cameraID of the target camera sensor) in storage location 1 through setstaticlastresindex(cameraID, resindex). The corresponding drawing mode identifier.

Take the target camera ID as 1, and the target camera sensor loads the 14bit Binning image output mode as an example. As shown in Table 2, the output mode identifier corresponding to the 14bit Binning image output mode is Setting mode1. mobile phone can call

setstaticlastresindex(1, 1), update the image output mode flag corresponding to cameraID "1" in storage location 1 from "255" to "1", indicating that the target camera sensor starts to enable the 14bit Binning image output mode.

S106, in the case that the camera mode 1 does not correspond to the FMC data package 1, and only corresponds to a set of mode parameters 1, the mobile phone instructs the target camera sensor to load the mode parameter 1.

In some embodiments, the mobile phone writes the mode parameter 1 into the target camera sensor, and instructs the target camera sensor to load the mode parameter 1.

In some other embodiments, after the target camera sensor loads the mode parameter 1, the mobile phone may update the image output mode identifier corresponding to the target camera identifier in the storage location 1. Wherein, the way of updating may refer to the above-mentioned embodiments, which will not be repeated here.

S107, the mobile phone instructs the target camera sensor to start image acquisition.

In some embodiments, the target camera sensor can perform image acquisition according to enabling the image output mode, and this process can also be referred to as streaming. After the image collected by the target camera sensor is preprocessed, an image frame is obtained. In this way, the mobile phone can display the image frame captured by the target camera sensor, that is, the first image frame.

Understandably, some camera modes in the electronic device support the switching of the multi-image output mode. In the case of enabling this type of camera mode, after the electronic device executes S105, the target camera sensor can be activated in a designated drawing mode, that is, S107 can be executed. Afterwards, the electronic device can switch between the output modes supported by the camera mode without interruption without continuous streaming.

Similarly, some camera modes in the electronic device may only support one image output mode. When this type of camera mode is enabled, after the electronic device executes S106, the target camera sensor can start streaming according to the output mode corresponding to the mode parameter 1, but cannot switch the output mode.

In some other embodiments, after the sensor of the target camera is activated, setstaticlastresindex(cameraID, resindex) can be called again, and in storage location 1, the output mode identifier corresponding to the target camera identifier is updated to ensure that the the validity of the data.

In some other embodiments, after the target camera sensor starts to capture image frames, that is, after the target camera sensor streams, the mobile phone can also determine whether the target camera sensor needs to stop working, such as whether to stop image acquisition (stream off). Wherein, in the case of detecting that the user indicates to switch the camera mode, the mobile phone may determine that the target camera sensor needs to stop working. The phone can also determine that the target camera sensor needs to stop working when it detects that the user has instructed the camera app to run in the background. The phone can also determine that the target camera sensor needs to stop working when it detects a user instruction to close the camera app. When it is detected that the user indicates to switch the target camera sensor, for example, when the target camera sensor is switched from the camera sensor of the main camera to the camera sensor of the wide-angle camera, the mobile phone may also determine that the target camera sensor needs to stop working. Of course, the embodiment of the present application does not specifically limit the rules for judging whether the target camera sensor stops working.

After controlling the sensor of the target camera to stop working, the mobile phone can call setstaticlastresindex(cameraID, resindex), and in storage location 1, change the output mode identifier corresponding to the target camera identifier to a sequence number indicating initialization (such as 255), indicating the No plot mode is currently enabled for the target camera sensor.

Taking the target camera ID as "1" as an example, after the target camera sensor stops working, the mobile phone can call setstaticlastresindex(1, 255), and in storage location 1, update the output mode ID corresponding to cameraID "1" to indicate Initialized sequence number "255". In this way, it can be recorded that the camera sensor whose cameraID is "1" does not currently enable any image output mode.

The following describes the signaling interaction between various modules of the mobile phone during the implementation of the above method. As shown in Figure 5:

S201 , in response to an operation indicating to start the camera application, run the camera application and determine the enabled camera mode 1 .

In some embodiments, the above operation of instructing to start the camera application may include the operation of instructing to start the camera application enumerated in S101 above, which will not be repeated here.

After running the camera application, the camera application can determine the currently enabled camera mode, that is, camera mode 1 . Likewise, for the manner of determining the camera mode 1, reference may be made to the descriptions in the foregoing embodiments, and details are not repeated here.

S202. The camera application sends the camera ID 1 matching the camera mode 1 to the camera service, where the camera ID 1 includes the target camera ID of the target camera sensor.

Wherein, the camera ID 1 is the camera ID (cameraID) of the camera sensor 1 . Camera Sensor 1 includes all camera sensors that can be enabled in Camera Mode 1. In this way, it can also be said that the camera ID 1 matches the camera model 1. It can be understood that, in the camera mode 1, the target camera sensor may be one of the camera sensors 1 .

S203. The camera service sends the camera identification 1 to the interface module.

S204. The interface module sends the camera identification 1 to the Sensor node.

S205, the Sensor node sends the camera identification 1 to the target camera driver.

S206, the target camera driver instructs the target camera sensor to be powered on.

In some embodiments, multiple camera sensors are configured in the mobile phone, and multiple camera sensors are also configured in the mobile phone. A camera driver corresponds to controlling a camera sensor. The camera driver corresponding to the target camera sensor may also be referred to as the target camera driver.

In addition, after the Sensor node receives the camera ID 1, it can send the camera ID 1 to all camera drivers. After the camera driver receives the camera ID 1, if it is determined that the camera ID 1 includes the camera ID of the camera sensor of the camera driver, the camera driver may instruct the corresponding camera sensor to be powered on. If it is determined that the camera identifier 1 does not include the camera identifier of the camera sensor of the camera driver, the camera driver may not respond.

In this way, after receiving the camera ID 1, the driver of the target camera may respond to the camera ID 1 and instruct the sensor of the target camera to be powered on.

S207, the target camera sensor is powered on.

In some embodiments, other camera sensors in the camera sensor 1 may also be powered on in response to the corresponding camera driving instructions.

S208, the Sensor node acquires public parameters from the XML.

In some embodiments, a plurality of camera parameters may be pre-configured in the memory of the mobile phone, and the plurality of camera parameters include public parameters and specific configuration parameters corresponding to each camera mode. It can be understood that when the camera mode supports multiple output modes, the dedicated configuration parameters corresponding to the camera mode may be FMC data packets. When the camera mode only supports one output mode, the dedicated configuration parameters corresponding to the camera mode can be mode parameters. In the subsequent embodiments, the camera mode 1 supports multiple drawing modes as an example for illustration. In addition, among the plurality of dedicated configuration parameters, the dedicated configuration parameter corresponding to camera mode 1 may be referred to as FMC data package 1 .

In addition, the above-mentioned public parameters and multiple dedicated configuration parameters can be mirrored into XML in the HAL layer, so that the XML of the HAL layer can include public parameters and multiple dedicated configuration parameters, such as public parameters and FMC data package 1. In this way, the Sensor node can also read the public parameters and FMC data package 1 from XML.

In some embodiments, after the camera sensors 1 are all powered on, the camera sensor 1 can feed back a message indicating that it has been powered on to the Sensor node, and the Sensor node can respond to the message and read the public parameters from the XML.

S209, the Sensor node sends public parameters to the target camera driver.

In some embodiments, the Sensor node can send common parameters to all camera drivers. In some other embodiments, the Sensor node may send public parameters to the camera driver controlling the camera sensor 1, which is not specifically limited in this embodiment of the present application.

Of course, whether the Sensor node sends public parameters to all camera drivers or to the camera driver controlling camera sensor 1, the target camera driver can receive the public parameters from the Sensor node.

S210, the target camera driver sends public parameters to the target camera sensor.

In some embodiments, the camera drivers that receive the public parameters can all send a public reference to the controlled camera sensor. When all camera drivers receive the public parameters, and some camera sensors are not powered on, the camera driver can only send the public parameters to the powered camera sensors. In the case that only the camera driver of camera sensor 1 receives the public parameters, the camera driver of camera sensor 1 may send the public parameters to camera sensor 1, instructing camera sensor 1 to load the public parameters.

Of course, no matter which of the above methods is adopted, the target camera sensor can receive public parameters from the target camera drive.

S211, the target camera sensor loads public parameters.

It can be understood that other camera sensors that have received the public parameters (eg, other camera sensor 1 ) can also load the above public parameters. In this way, even if other camera sensors 1 do not need to collect original images for the time being, and do not need to return the collected images to the display, the public parameters can also be preloaded.

In addition, for the manner of loading public parameters by the target camera sensor, reference may be made to the process of loading camera parameters by the camera sensor in the related art, which will not be repeated here.

S212, the target camera sensor sends a completion notification 1 to the target camera driver.

S213, the target camera driver sends a completion notification 1 to the Sensor node.

Wherein, the above-mentioned completion notice 1 indicates that the configuration of the public parameters of the target camera sensor is completed.

S214. In response to the completion notification 1, the Sensor node acquires the FMC data packet 1 corresponding to the camera mode 1 from the XML.

In some embodiments, after it is determined that the camera mode 1 is enabled, the camera application may notify the Sensor node that the camera mode 1 needs to be enabled. In addition, each dedicated configuration parameter can be marked with a corresponding camera mode in advance, for example, FMC data packet 1 can be marked as corresponding to camera mode 1. In this way, when the enabled camera mode is camera mode 1, the Sensor node can obtain FMC data packet 1 corresponding to camera mode 1 from XML.

S215, the Sensor node sends the FMC data packet 1 to the target camera driver.

S216, the target camera driver sends the FMC data packet 1 to the target camera sensor.

S217, the target camera sensor configures the FMC data packet 1.

In some embodiments, after the target camera sensor receives and stores the FMC data packet 1, the Sensor node determines that the target camera sensor does not enable any drawing mode at this time, so that the Sensor node instructs the target camera sensor to load the FMC data packet through the target camera driver The default mode parameter in 1, so that the target camera sensor enables the corresponding default output mode of camera mode 1.

Take camera mode 1 as the camera mode as an example. The default image output mode of the camera mode is 14bit binning image output mode. When the Sensor node determines that the target camera sensor does not enable any image output mode, it can send commands to the target camera driver by " INSENSORZOOMNONE", so that the target camera driver controls the target camera sensor to load the mode parameters corresponding to the 14-bit binning output mode in FMC data packet 1.

It can be understood that when a camera mode supports multiple image output modes, the camera mode corresponds to a default image output mode, so that the FMC data packet corresponding to the camera mode includes default mode parameters corresponding to the default image output mode. The target camera sensor can enable the corresponding default output mode by loading the default mode parameters in the FMC data package. In this way, after the FMC data packet 1 is delivered, it is not necessary to repeatedly write the default mode parameters into the target camera sensor, and use the default flag of the default mode parameter in the FMC data packet 1 to trigger the target camera sensor to load the default mode parameters.

The above S214 to S217 are the process of configuring the dedicated configuration parameters of the camera mode 1 for the target camera sensor. In other embodiments, if camera mode 1 only supports one output mode, and the dedicated configuration parameter of camera mode 1 is mode parameter 1, the Sensor node can also obtain mode parameter 1 from XML according to camera mode 1 , and instruct the target camera sensor to directly load the mode parameter 1 through the target camera driver. In this way, the target camera sensor can enable the drawing mode corresponding to the mode parameter 1.

S218, the target camera sensor sends a completion notification 2 to the target camera driver.

S219, the target camera driver sends a completion notification 2 to the Sensor node.

Wherein, the above completion notification 2 indicates that the target camera sensor has completed the configuration of the dedicated configuration parameters.

S220, the Sensor node sends a stream instruction to the target camera driver.

S221, the target camera driver sends a flow command to the target camera sensor.

S222. The target camera sensor outputs an image according to the default image output mode corresponding to the FMC data packet 1.

Wherein, each FMC data packet corresponds to a camera mode, thus, the default image output mode corresponding to the FMC data packet 1 may be the default image output mode corresponding to the camera mode 1.

In other embodiments, when the specific configuration parameter configured by the target camera sensor is the mode parameter 1, the target camera sensor outputs the image according to the image output mode indicated by the mode parameter 1.

In some embodiments, as shown in Figure 6, the above method also includes:

S223, the target camera sensor responds to the flow instruction, and collects original image data.

Wherein, the output mode corresponding to the original image data is the default output mode of the camera mode 1.

S224, the target camera sensor sends the original image data to the target camera driver.

S225, the target camera driver sends the original image data to the image processing module.

In some embodiments, the target camera sensor transmits the collected raw image data to the image processing module through the driving of the target camera, so that the image processing module can process the raw image data.

S226, the image processing module processes the original image data to obtain image frames.

In some embodiments, the principle of processing the original image data by the image processing module may refer to related technologies, which will not be repeated here.

S227. The image processing module transmits the image frame to the interface module.

S228. The interface module transmits the image frame to the camera service.

S229, the camera service transmits the image frame to the camera application.

In some embodiments, the image processing module transparently transmits the processed image frames to the camera application through the interface module and the camera service.

S230, the camera application displays the image frame.

In some embodiments, after receiving the image frame, the camera application may instruct to display the image frame in the application interface of the camera mode. As shown in FIG. 3 , the mobile phone may display an interface 304 . Exemplarily, after the camera application receives an image frame (for example, referred to as the first image frame), it may schedule the view system in the application framework layer, and display the image frame through the view system.

In some embodiments, when the camera mode 1 supports multiple image output modes, during the operation of the camera application in the camera mode 1, the camera application can also dynamically switch between different image output modes according to the change of the shooting scene.

Taking camera mode 1 as the photo mode as an example, in different shooting scenarios, the adapted output modes are shown in Table 3:

table 3

Wherein, under different zoom magnifications, methods for judging a dark environment and a bright environment may be different.

Exemplarily, when the unit of the zoom ratio is 0.1X, and the zoom ratio is from 1X to 1.9X, the mobile phone may Bit, to judge the current lighting environment. Wherein, the light environment is divided into a bright environment and a dark environment.

For example, if the calculated luminance (lv) is greater than a preset value 1 (may be referred to as a first threshold, eg, 50), and the HDR flag indicates that the mobile phone enters an HDR scene, it can be determined that the current lighting environment is a bright environment. Wherein, the above preset value 1 may be an empirical value, and the embodiment of the present application does not limit the specific value of the preset value 1 . In addition, the aforementioned HDR scene refers to a shooting scene where the HDR technology needs to be enabled, for example, a shooting field of view includes both a high-brightness area and a low-brightness area.

For example, the calculated luminance (lv) is not greater than the preset value 1 (eg, 50), or the HDR flag indicates that the mobile phone has not entered the HDR scene, so it can be determined that the current lighting environment is a dark environment.

In this way, when the zoom ratio is between 1X and 1.9X, if it is determined that the current lighting environment is a bright environment, it is determined that the target camera sensor enables the 14bit Idcg image output mode. If it is determined that the current lighting environment is a dark environment, make sure that the target camera sensor enables the 14bit binning image output mode.

Exemplarily, when the unit of the zoom ratio is 0.1X, and the zoom ratio is from 2X to 2.5X, the mobile phone can judge the current lighting environment according to the calculated illuminance quantification value (luxindex). Wherein, the illuminance quantification value (luxindex) is a parameter calculated by the mobile phone according to the detected ambient illuminance (lux). For example, the mobile phone evaluates the parameter values based on the latest collected RAW image through the ISP. Of course, the larger the value of the illuminance quantization value (luxindex), the darker the actual ambient brightness is, and the smaller the illuminance quantization value (the first illuminance quantization value, such as luxindex), the smaller the actual ambient brightness (lux) brighter.

For example, if the illuminance quantification value (luxindex) is less than a preset value 2 (the second threshold, eg, 350), it may be determined that the current lighting environment is a bright environment. Wherein, the above preset value 2 may be an empirical value, and the embodiment of the present application does not limit the specific value of the preset value 2 .

For example, if the illuminance quantification value (luxindex) is not less than a preset value 2 (for example, 350), it can be determined that the current lighting environment is a dark environment.

In this way, when the zoom ratio is between 2X and 2.5X, if it is determined that the current lighting environment is a bright environment, it is determined that the target camera sensor enables the 14bit Remosaic image output mode. If it is determined that the current lighting environment is a dark environment, make sure that the target camera sensor enables the 14bit binning image output mode.

It is understandable that in a dark environment, the image brightness gradient difference is small. In this scenario, the binning image output mode with better sensitivity and lower power consumption can be used to obtain an imaging effect with better sensitivity. That is, no matter what the zoom ratio of the mobile phone is, if the lighting environment is determined to be dark, the binning image output mode is preferred.

In a bright environment, when the zoom ratio is between 1X and 1.9X, the field of view of the camera is wide, and the brightness gradient of the collected images is quite different. In this scene, enabling the Idcg image output mode can achieve the best image output effect.

In a bright environment, when the zoom ratio is between 2X and 2.5X, the sensitivity of the Remosaic output mode is sufficient, and the image pixels are more, and the definition is higher.

In some embodiments, under the first condition, it is determined that the target camera sensor activates the second image output mode, and under the second condition, it is determined that the target camera sensor activates the third image output mode. Under the third condition, it is determined that the target camera sensor enables the first drawing mode.

In the case that camera mode 1 is a photographing mode, and the second drawing mode is an Idcg drawing mode, the above-mentioned first condition indicates a scene suitable for enabling the Idcg drawing mode, for example, it may be when the zoom ratio belongs to 1X-1.9X ( That is, during the first interval), the condition of a bright environment is recognized.

In the case that camera mode 1 is a photographing mode, and the third drawing mode is a Remosaic drawing mode, the above-mentioned second condition indicates a scene suitable for enabling the Remosaic drawing mode, for example, it may be when the zoom factor belongs to 2X-2.5X ( That is, during the second interval), the condition of a bright environment is recognized.

In the case that the camera mode 1 is a photographing mode, and the third drawing mode is a binning drawing mode, the above-mentioned third condition indicates a scene suitable for enabling the binning drawing mode, for example, when the zoom ratio belongs to the second range, The condition for recognizing the dark environment may also be, for example, the condition for recognizing the dark environment when the zoom ratio belongs to the first range.

Taking camera mode 1 as portrait mode as an example, in different shooting scenarios, the adapted output modes are shown in Table 4:

Table 4

Among them, in the portrait mode, the optional zoom ratios include 1X, 2X and 3X.

As an implementation manner, in the portrait mode, the mobile phone may determine that the current lighting environment is a bright environment when the illuminance quantification value (luxindex) is less than a preset value 3 (eg, 290). The mobile phone may determine that the current lighting environment is a dark environment when the illuminance quantification value (luxindex) is not less than the preset value 3. Wherein, the preset value 3 may be an empirical value, and the embodiment of the present application does not limit its specific value.

As another implementation method, after the portrait mode is enabled, the mobile phone may judge according to whether the actually calculated illuminance quantification value (luxindex) is less than the preset value 3 in the process of judging the lighting environment for the first time. After portrait mode is enabled, if the last time the lighting environment is determined to be a bright environment, and the calculated illumination quantification value (luxindex) is greater than the sum of the preset value 3 and the margin value 1 (for example, 75), determine the lighting The environment becomes a dark environment.

When it is determined that the lighting environment belongs to the dark environment last time, if the calculated illuminance quantification value (luxindex) is less than the difference between the preset value 3 and the margin value 1 (eg, 75), it is determined that the lighting environment becomes a bright environment.

In the portrait mode, when the zoom ratio of the mobile phone is 3X, the mobile phone uses the TELE camera to collect images in a bright environment. In this scene, the target camera sensor is the camera sensor of the TELE camera. When the mobile phone is in a dark environment, enable the main camera to collect images. In this scenario, the target camera sensor is the camera sensor of the main camera. In this way, when the zoom ratio of the mobile phone is 3X, although the binning image output mode is enabled in both the bright environment and the dark environment, in the dark environment, the binning image output mode for the main camera is enabled. In a bright environment, enable the binning output mode for TELE cameras.

In the portrait mode, when the zoom ratio of the mobile phone is 1X, the target camera sensor can be any one of the camera sensors that can be enabled in the portrait mode. In this scenario, no matter in a dark environment or a bright environment, the target camera sensor will enable its own 10bit binning image output mode.

In the portrait mode, when the zoom ratio of the mobile phone is 2X, the target camera sensor can be any one of the camera sensors that can be enabled in the portrait mode. In this scenario, in a dark environment, the target camera sensor enables its own 10bit binning output mode. In a bright environment, the target camera sensor enables its own 10bit Remosaic output mode.

It is understandable that in portrait mode, when the zoom ratio of the mobile phone is 1X, the field of view (FOV) is normal and the sensitivity is better. In this scene, no matter in a bright environment or a dark environment, binning with low power consumption is used. The income of the drawing mode is higher.

In addition, in the portrait mode, when the zoom ratio of the mobile phone is 2X, in a dark environment, the benefit of using the binning image output mode with better sensitivity and lower power consumption is higher. In portrait mode, when the zoom ratio of the mobile phone is 2X, in a bright environment, the sensitivity of the Remosaic image output mode is sufficient, and the image pixels are more, and the definition is higher. The benefit of using the Remosaic image output mode is higher.

In portrait mode, when the zoom ratio of the mobile phone is 3X, in a dark environment, the camera sensor of the main camera has better sensitivity when the binning output mode is enabled. When the zoom ratio of the mobile phone is 3X, in a bright environment, the sensitivity of the TELE camera sensor can meet the requirements when the binning image output mode is enabled, and the collected pixels are more with high definition.

Taking camera mode 1 as video recording mode as an example, in different shooting scenarios, the adapted output modes are shown in Table 5:

table 5

dark environment bright environment 14bit binning output mode 14bit Idcg output mode

Wherein, in the video recording mode, the mobile phone may judge the lighting environment in the following manner: according to adaptive dynamic range compression (adaptive dynamic range compression, Adrc) gain, DarkLuma and luminance (lv), the current lighting environment is judged.

Wherein, the Adrc gain is a parameter indicating the dynamic range. For the calculation method of the Adrc gain, reference may be made to related technologies, for example, a frame of RAW image is obtained according to the current exposure parameters. Then, the overall average exposure of the RAW image and the average exposure of bright areas in the RAW image are obtained. In this way, the quotient between the overall average exposure of the RAW image and the average exposure of bright areas is determined as the Adrc gain.

DarkLuma is a parameter representing the average brightness of the dark area of the picture, and its calculation method can also refer to related technologies, which is not specifically limited in this embodiment of the present application.

Exemplarily, when the Adrc gain is less than a preset value of 4 (eg, 1.6) or DarkLuma is greater than a preset value of 5 (eg, 36), if the brightness (lv) is less than a preset value of 6 (eg, 46), Make sure that the current lighting environment is a dark environment. In addition, the above preset value 4, preset value 5 and preset value 6 are all empirical values, and specific values are not limited.

Exemplarily, when the Adrc gain is greater than a preset value of 7 (eg, 2.2) or DarkLuma is less than a preset value of 8 (eg, 27), if the brightness (lv) is greater than a preset value of 9 (eg, 50), Determine that the current lighting environment belongs to the bright environment. In addition, the above preset value 7, preset value 8 and preset value 9 are all empirical values, and the specific values are not limited. Of course, the preset value 7 is greater than the preset value 4, and the preset value 8 is smaller than the preset value 5. The default value of 9 is greater than the default value of 6.

It is understandable that in video recording mode, in a dark environment, the brightness gradient difference of the image is small, and it is better to use the binning image output mode with good sensitivity and low power consumption. In video recording mode, in a bright environment, the brightness gradient of the image is large, and the benefit of using the Idcg image output mode with better dynamic range is higher.

As shown in Figure 7, after the mobile phone is in camera mode 1 and instructs the target camera sensor to enable the default image output mode, the above camera parameter configuration method may also include:

S301. When no operation indicating to switch the camera mode is detected, the mobile phone determines the image output mode 1 suitable for the current shooting scene.

In some embodiments, the camera application is still running in camera mode 1 during the period when an operation indicating to switch the camera mode is not detected. During this period, the mobile phone can periodically determine a picture output mode suitable for the current shooting scene, such as called picture output mode 1.

Taking camera mode 1 as a camera mode as an example, the mobile phone can identify the current lighting environment according to the zoom ratio, combined with the HDR flag, luminance (lv) or illuminance quantification value (luxindex). Wherein, in the photographing mode, the details of identifying the lighting environment may refer to the foregoing embodiments, which will not be repeated here. Then, according to the identified lighting environment, combined with the zoom ratio and Table 3 in the foregoing embodiments, determine the image output mode 1 that matches the current shooting scene. For details, refer to the foregoing embodiments, and details are not repeated here.

Taking the camera mode 1 as the portrait mode as an example, the mobile phone can identify the current lighting environment according to the illuminance quantification value (luxindex). Wherein, in the portrait mode, the details of identifying the lighting environment may refer to the foregoing embodiments, which will not be repeated here. Then, according to the identified lighting environment, combined with the zoom ratio and Table 4 in the foregoing embodiments, the image output mode 1 matching the current shooting scene is determined. For details, please refer to the foregoing embodiments, which will not be repeated here.

Taking camera mode 1 as video recording mode as an example, the mobile phone can identify the current lighting environment according to Adrc gain, DarkLuma and brightness (lv). Wherein, in the video recording mode, the details of identifying the lighting environment may refer to the foregoing embodiments, which will not be repeated here. Then, according to the identified lighting environment and in combination with Table 5 in the foregoing embodiments, an image output mode 1 matching the current shooting scene is determined. For details, reference may be made to the foregoing embodiments, which will not be repeated here.

S302. Instruct the target camera sensor to seamlessly switch to the image output mode 1 when the image output mode 1 is different from the image output mode currently enabled by the target camera sensor.

In some embodiments, the mobile phone may identify the image output mode currently enabled by the target camera sensor, and then compare image output mode 1 with the image output mode currently enabled by the target camera sensor. In the case that drawing mode 1 is the same as the drawing mode being activated, the switching of the drawing mode is not performed. In the case that image output mode 1 is the same as the currently enabled image output mode, instruct the target camera sensor to seamlessly switch to image output mode 1, that is, enable image output mode 1 by means of seamless switching.

As an implementation manner, the mobile phone may use the function Updatelastresindex(cameraID) to query the latest image output mode ID recorded by the target camera sensor from the storage location 1 as the image output mode ID of the currently enabled image output mode. Then, by comparing whether the drawing mode identifier of the drawing mode 1 is the same as that of the drawing mode being activated, it is determined whether to switch the mode.

For example, if the cameraID of the target camera sensor is "1", you can call Updatelastresindex(1) to determine the output mode ID corresponding to the target camera sensor recorded last time, for example, the output mode ID fed back by Updatelastresindex(1) It is setting mode1. In this way, when the drawing mode flag of drawing mode 1 is also setting mode1, it is determined not to switch the drawing mode. When the drawing mode flag of drawing mode 1 is not setting mode1, it is determined to switch to enable drawing mode 1.

When it is determined that the image output mode 1 needs to be switched, the mobile phone determines whether the mode parameters loaded by the target camera sensor and the mode parameters corresponding to the image output mode 1 belong to the same FMC data packet. If they belong to the same FMC data packet, seamless switching can be performed. For implementation details, refer to the description in subsequent embodiments, and details will not be repeated here.

Exemplarily, in the case that the exclusive configuration parameter is an FMC data packet, the FMC data packet further includes an identifier of a drawing mode corresponding to each mode parameter. Of course, when the exclusive configuration parameter is a mode parameter, the exclusive configuration parameter also includes the identifier of the drawing mode corresponding to the mode parameter. Through the function Getcustomsettings, the mobile phone can read the image output mode ID corresponding to the target camera ID from the storage address 1, and the read image output mode ID can indicate the image output mode currently enabled by the target camera sensor. Then, compare the read output mode identifier with the output mode identifier in the exclusive configuration parameter 1. Among them, the exclusive configuration parameter 1 includes the mode parameters of the image output mode 1 and the image output mode identifier of the image output mode 1. If the read output mode ID is the same as another output mode ID in dedicated configuration parameter 1, perform seamless switching.

In some other embodiments, after the seamless switching, the target camera sensor enables the output mode 1 . After the image output mode 1 is enabled by the target camera sensor, the mobile phone may update the image output mode identifier corresponding to the target camera identifier in the storage location 1. The updated drawing mode identifier may be the drawing mode corresponding to drawing mode 1. It can be understood that every time the camera sensor updates the image output mode, it will update the corresponding image output mode identifier in the storage location 1. In this way, it can be ensured that the image output mode identifier recorded in the storage location 1 can indicate the image output mode currently enabled by the camera sensor. Plot mode.

The following takes the mobile phone in camera mode 1 and switches from the default image output mode to image output mode 1 according to the shooting scene as an example to introduce the implementation details of switching image output modes in the same camera mode.

As shown in Figure 8, the above camera parameter configuration method may include the following steps:

S401. The decision-making module determines that image output mode 1 is suitable for the current shooting scene.

In some embodiments, if the camera application switches the camera mode, the decision module may be notified through the camera service. In addition, if the camera application changes the zoom ratio in response to the user's operation, it will also send the changed zoom ratio to the decision-making module through the camera service. In this way, the decision-making module can obtain the zoom ratio enabled by the camera application in time.

In the case that the camera application does not notify the decision-making module to switch the camera mode, the decision-making module can identify the current lighting environment, and determine the image output mode suitable for the current shooting scene according to the current lighting environment and/or the currently enabled zoom ratio, That is, drawing mode 1. Of course, for specific implementation details, reference may be made to S301 in the foregoing embodiments, and details are not repeated here.

In some embodiments, the decision module may periodically determine the image output mode 1 according to the lighting environment and/or the last received zoom ratio if no notification indicating to switch the camera mode is received.

In some other embodiments, when no notification indicating to switch the camera mode is received, the decision-making module may receive a new zoom ratio, or determine that the lighting environment changes, according to the lighting environment and the last received The zoom magnification to determine the output mode 1.

S402. The decision-making module sends a graph output mode identifier 1 to the Sensor node, where the graph output mode identifier 1 corresponds to the graph output mode 1.

S403, the Sensor node determines that the mode parameter of the drawing mode 1 also belongs to the FMC data package 1.

In some embodiments, the Sensor node can read the output mode identifier corresponding to the target camera identifier from storage address 1 through the function Getcustomsettings. Then, compare the read output mode identifier with the output mode identifier in the exclusive configuration parameter 1. Among them, the exclusive configuration parameter 1 includes the mode parameters of the image output mode 1 and the image output mode identifier of the image output mode 1. If the output mode identifier read is the same as any one of the output mode identifiers in the exclusive configuration parameter 1, it is determined that the mode parameters of the output mode 1 also belong to the FMC data package 1, that is, the exclusive configuration parameter 1 is the FMC data package 1 .

S404, the Sensor node sends an instruction to the target camera driver to enable image output mode 1.

Exemplarily, in the case that the default drawing mode is the binning drawing mode, if the drawing mode 1 is the Remosaic drawing mode, the command indicating to enable the drawing mode 1 may be INSENSORZOOM CROP. If the drawing mode 1 is the Idcg drawing mode, the instruction to enable the drawing mode 1 can be INSENSORZOOM IDCG. When the default image output mode is not binning image output mode, image output mode 1 is binning image output mode, or needs to be switched from other image output modes to binning image output mode, the Sensor node sends the command "INSENSORZOOMBINNING" to the target camera driver .

S405, the target camera driver sends the switch field 1 to the target camera sensor. Switch field 1 in FMC packet 1 corresponds to drawing mode 1.

In some embodiments, after the target camera driver receives the instruction to enable the image output mode 1, it may determine whether the current image output mode of the target camera sensor is the same as the image output mode 1. For example, it may be compared whether two adjacent received instructions for enabling the image output mode are the same, and if they are the same, it may be determined that the current image output mode of the target camera sensor is the same as image output mode 1. If not, it can be determined that the current image output mode of the target camera sensor is different from image output mode 1.

In the case that the current image output mode of the target camera sensor is different from image output mode 1, the target camera driver can obtain the switch field 1 corresponding to image output mode 1 from the FMC packet 1, and send it to the target camera sensor.

For example, the image output mode 1 is the second image output mode, and the corresponding switch field 1 may be the first information. For another example, the image output mode 1 is the third image output mode, and the corresponding switch field 1 may be the second information. For another example, the drawing mode 1 is the first drawing mode, and the corresponding switch field 1 may be the third information.

In addition, the data volume of the switch fields (eg, the first information, the second information and the third information) is much smaller than the mode parameter corresponding to the drawing mode. Instructing the target camera sensor to switch the image output mode by writing the switch field is faster than writing the mode parameter instruction to switch the image output mode.

S406. After loading the switch field 1, the target camera sensor loads the mode parameters corresponding to the image output mode 1 from the FMC data packet 1.

In this way, the target camera sensor can perform image acquisition according to the drawing mode 1. Through the above steps, the target camera sensor is switched from the default image output mode to image output mode 1, and the switching process can be called seamless switching. In the embodiment of this application, in the process of instructing the target camera sensor to complete the seamless switching, it is not necessary for the target camera sensor to stop working, and it is not necessary to send a large volume of mode parameters to the target camera sensor. It is only necessary to send a lightweight switch field. To achieve switching, convenient and quick.

After switching to enable the image output mode 1, the mobile phone can display the image frames collected by the image output mode 1. For example, when the image output mode 1 is the second image output mode, the second image frame is displayed on the first interface. When image output mode 1 is the third image output mode, the third image frame is displayed on the first interface. When the image output mode is switched back to the first image output mode from other image output modes, the fourth image frame is displayed on the first interface.

Exemplarily, as shown in FIG. 9 , when the camera application activates the photographing mode, the mobile phone may display a photographing preview interface 901 provided by the photographing mode. In the shooting preview interface 901, an image frame 902 from the main camera is displayed, that is, the camera sensor of the main camera may be called a target camera sensor. In addition, the shooting preview interface 901 also displays that the current zoom ratio is 1X.

When the mobile phone recognizes that the current lighting environment is a bright environment and displays the shooting preview interface 901 , the target camera sensor uses the 14bit Idcg image output mode to output images.

In addition, the shooting preview interface 901 also includes a zoom bar 902 . A slide window 903 is displayed on the zoom bar 902 . It can be understood that different positions in the zoom bar 902 correspond to different zoom ratios. The zoom magnification indicated by the point where the sliding window 903 overlaps the zoom bar 902 is the currently selected zoom magnification. In addition, the sliding window 903 can also display the numerical value of the currently selected zoom ratio.

In some embodiments, when the mobile phone receives the user's sliding operation on the zoom bar 902, it may determine that the zoom operation is received. The sliding operation can instruct the sliding window 903 to adjust the position overlapped with the zoom bar 902, thereby instructing to modify the selected zoom ratio. After the user's sliding operation is completed, the mobile phone can obtain the changed zoom ratio. For example, as shown in FIG. 9 , the user instructs to change the selected zoom ratio from 1X to 2X, and after it is determined that the zoom ratio enabled by the user instruction is changed to 2X, the mobile phone may display a shooting preview interface 904 . The shooting preview interface 904 shows that the current zoom ratio is 2X, and the shooting preview interface 904 still displays image frames from the main camera, that is, the target camera sensor remains unchanged.

The difference is that when the mobile phone recognizes that the current lighting environment is a bright environment and displays the shooting preview interface 904, the target camera sensor uses the 14bit Idcg image output mode to output images.

In addition, when switching from the shooting preview interface 901 to the shooting preview interface 904 , the image output mode of the target camera sensor has changed. Of course, in the process of changing the drawing mode, the sensor of the target camera does not stop streaming, that is, does not stop working. In this way, when the mobile phone transitions from displaying the shooting preview interface 901 to displaying the shooting preview interface 904, no black screen appears. After determining that the zoom ratio is 2X, you only need to write a lightweight switch field to the target camera sensor to quickly complete the mode switching.

In short, in the same camera mode, in the process of switching between different image output modes, you only need to write a lightweight switch field to the target camera sensor to achieve fast image output mode switching. Compared with writing the mode parameters of the switched output mode into the camera sensor, the amount of written data is reduced and the switching time is shortened.

In some embodiments, during the running of the camera application, different camera modes may be switched and enabled in response to user operations. For example, switching from the photo mode to the portrait mode, another example, switching from the portrait mode to the video mode, and another example, switching from the photo mode to the video mode, etc.

The following takes the mobile phone switching from camera mode 1 to camera mode 2 as an example to introduce the implementation details of the camera application switching between different camera modes.

As shown in Figure 10, the above camera parameter configuration method may also include the following steps:

S501 , the camera application detects an operation of switching the camera mode 2 .

In some embodiments, when the mobile phone displays the application interface provided by the camera mode 1, it may detect the user's operation instructing to switch the camera mode 2, such as a second operation or a third operation. Wherein, the above-mentioned second operation and the third operation indicate that the enabled camera mode 2 may be different. For example, the second operation indicates enabling the video recording mode, and the third operation indicates enabling the portrait mode.

For example, as shown in FIG. 11 , the mobile phone displays a shooting preview interface 901 provided by the camera mode. The shooting preview interface 901 includes controls indicating other camera modes, for example, a control 1101 indicating a recording mode. When the mobile phone detects that the user selects the control 1101, the mobile phone can switch to display the video preview interface 1102, that is, enable the video recording mode. In the above process, the video recording mode is the camera mode 2, and the operation of selecting the control 1101 by the user may be referred to as an operation of instructing to switch the video recording mode.

For another example, if the mobile phone detects a voice password issued by the user indicating to switch the camera mode 2, it may also determine that an operation indicating to switch the camera mode 2 is detected. For another example, if a gesture indicating to switch camera mode 2 is detected, it may also be determined that an operation indicating to switch camera mode 2 is detected.

S502. The camera application sends notification information 1 to the Sensor node. The notification information 1 indicates that camera mode 2 needs to be enabled.

In some embodiments, the camera application can call the interface module of the HAL layer through the camera service, and send notification information 1 to the Sensornode.

Different camera modes 2 are enabled, and the types of preview interfaces displayed by the mobile phone are different. For example, the mobile phone may display a second interface in response to the second operation, and the second interface may be a second type of preview interface. In response to the third operation, the mobile phone may display a third interface, and the third interface may be a third-type preview interface, that is, the types of the second interface and the third interface may be different. In response to the second operation, the enabled camera mode 2 may be referred to as a first-type camera mode 2 , and the camera sensors that can be enabled in the first-type camera mode 2 are the same as the camera sensors that can be enabled in the camera mode 1 .

In response to the third operation, the enabled camera mode 2 may be referred to as a second type of camera mode 2 , and the camera sensors that can be enabled in the second type of camera mode 2 are different from the camera sensors that can be enabled in camera mode 1 .

S503, the Sensor node sends information indicating to stop working to the target camera driver.

S504, the target camera driver sends information indicating to stop working to the target camera sensor.

S505, the target camera sensor stops image acquisition.

S506. The Sensor node determines that the camera sensor 2 corresponding to the camera mode 2 is the same as the camera sensor 1.

In some embodiments, there is no necessary sequence between the above S506 and S503, and they are all steps performed by the Sensor node in response to the notification information 1 .

After the Sensor node receives the notification information 1, it can determine whether the camera sensor 2 corresponding to the camera mode 2 is exactly the same as the camera sensor 1 corresponding to the camera mode 1. Wherein, camera sensor 2 is the camera sensor of the camera that can be used when camera mode 2 is enabled. For example, camera sensor 2 includes camera sensors corresponding to front camera 1, front camera 2, and rear camera 1, and camera sensor 1 also includes camera sensors corresponding to front camera 1, front camera 2, and rear camera 1. , it can be determined that camera sensor 2 is identical to camera sensor 1. For another example, camera sensor 2 includes camera sensors corresponding to front camera 1 and rear camera 1, and camera sensor 1 also includes camera sensors corresponding to front camera 1, front camera 2, and rear camera 1. Sensor 2 is not exactly the same as camera sensor 1.

In the case that the camera sensor 2 is not exactly the same as the camera sensor 1, for example, after the third interface is displayed in response to the third operation, it is necessary to control the camera sensor 1 to be powered off, and then control the camera sensor 1 to be powered on. Then, instruct the camera sensor 2 to configure public parameters, and after the configuration of the public parameters is completed, the process goes to S507. In the case that the camera sensor 2 is identical to the camera sensor 1, for example, after the second interface is displayed in response to the second operation, the process goes to S507.

S507. The Sensor node obtains the FMC data packet 2 corresponding to the camera mode 2 from the XML.

In some embodiments, the dedicated configuration parameters corresponding to camera mode 2 also belong to pre-configured camera parameters. In this way, the exclusive configuration parameters of the camera mode 2 can also be stored in the XML.

In some embodiments, the Sensor node obtains the dedicated configuration parameters corresponding to the camera mode 2 from the XML. In this embodiment, taking camera mode 2 as an example that supports multiple output modes, the dedicated configuration parameters corresponding to camera mode 2 may also be FMC data packets, such as FMC data packet 2 . The FMC data packet 2 is similar to the FMC data packet 1, but the two correspond to different camera modes, and may contain different content such as mode parameters, switch fields, and drawing mode identifiers. In addition, the FMC data packet 2 can be marked with the identifier of the camera mode 2, so that the Sensor node can directly read the FMC data packet 2 from XML.

In other possible embodiments, if the camera mode 2 supports only one image output mode, the dedicated configuration parameters corresponding to the camera mode 2 may be the mode parameters corresponding to the image output mode. In this way, after the Sensor node obtains the mode parameters of the camera mode 2, it can instruct the target camera sensor to load the mode parameters through the target camera driver, so as to enable the output mode supported by the camera mode 2.

Exemplarily, after the second interface is displayed in response to the second operation, the FMC data packet 2 written to the target camera sensor (that is, the first camera sensor) may be the second data packet. In the case that the first type of camera mode 2 supports the fourth drawing mode, the second data packet may include mode parameters corresponding to the fourth drawing mode, that is, the fifth configuration parameter, which includes enabling the fourth drawing mode In the camera parameters (or called attribute parameters) of the four-out image mode, the part other than the common parameters. In addition, when the second data packet also includes mode parameters of other image output modes, the fourth image output mode also has a second identification in the second data packet. After the target camera sensor is loaded with public parameters, it has the ability to identify The second identification, based on the second identification, triggers the ability to load the fifth configuration parameter.

As another example, after the third interface is displayed in response to the third operation, the FMC data packet 2 written to the target camera sensor (that is, the second camera sensor) may be the third data packet. In the case that the second type of camera mode 2 supports the fifth drawing mode, the third data packet may include the mode parameters corresponding to the fifth drawing mode, that is, the sixth configuration parameter, which includes enabling the fifth drawing mode Among the camera parameters (or called attribute parameters) of the five-image output mode, the part other than the common parameters. In addition, when the third data packet also includes mode parameters of other image output modes, the fifth image output mode in the third data packet also corresponds to a third identification, and the target camera sensor is capable of identifying The third identification, based on the third identification, triggers the ability to load the sixth configuration parameter.

S508, the Sensor node sends the FMC data packet 2 to the target camera driver.

S509, the target camera driver sends the FMC data packet 2 to the target camera sensor.

S510, the target camera sensor configures FMC data packet 2.

In some embodiments, for the implementation details of configuring the FMC data package 2, reference may be made to the process of configuring the FMC data package 1 in the foregoing embodiments, which will not be repeated here.

S511, the target camera sensor sends a completion notification 3 to the target camera driver.

S512. The target camera drives to send a completion notification 3 to the Sensor node.

S513, the Sensor node sends a stream instruction to the target camera driver.

S514, the target camera driver sends a flow command to the target camera sensor.

S515. The target camera sensor outputs an image according to the default image output mode corresponding to the FMC data packet 2.

In some embodiments, for implementation details of the foregoing S511-S515, reference may be made to S218-S222 in the foregoing embodiments, and details are not repeated here.

For example, when the FMC data packet 2 written to the target camera sensor is the second data packet, after the target camera sensor outputs the image, the mobile phone can display the fifth image frame on the second interface, and the fifth image frame is the target The camera sensor adopts the image obtained by the fourth image output mode.

For example, when the FMC data packet 2 written to the target camera sensor is the third data packet, after the target camera sensor outputs the image, the mobile phone can display the sixth image frame on the third interface, and the sixth image frame is the target The image obtained by the camera sensor using the fifth image output mode.

It can be understood that during the display of the second interface (that is, during the activation of the first type of camera mode 2), the enabled camera sensor and during the display of the third interface (that is, during the activation of the second type of camera mode 2), the enableable There are differences in the camera sensors, such that the first camera sensor and the second camera sensor may be the same camera sensor or different camera sensors.

In the switching process of camera modes described in S501-S515 above, if the camera sensors corresponding to camera mode 1 and camera mode 2 remain unchanged, there is no need to send public parameters again, reducing the amount of data written to the target camera sensor , which effectively shortens the time required for camera mode switching.

In addition, the first type of preview interface, the second type of preview interface and the third type of preview interface may be any one of: a photo preview interface, a video recording interface, and a portrait shooting interface. The above-mentioned first type preview interface, second type preview interface and third type preview interface may be different.

In some embodiments, as shown in FIG. 12 , the mobile phone configures the image output mode of the target camera sensor and switches the image output mode as follows: First, the target camera sensor needs to receive public parameters and perform configuration. Then, when it is necessary to enable image output mode 3, the target camera sensor receives and configures mode parameter 3, which is a dedicated configuration parameter corresponding to image output mode 3. In this way, the target camera sensor can follow the corresponding mode parameter 3 The drawing mode 3 is used to export the drawing. After receiving and configuring mode parameter 3, if you need to switch to enable image output mode 4, the target camera sensor can suspend work (stream off), and then receive and configure mode parameter 4, which is exclusive to image output mode 4 configuration parameters. In this way, the target camera sensor can output images according to the image output mode 4 corresponding to the mode parameter 4 .

Of course, after the target camera sensor receives and configures the public parameters, if the image output mode 4 needs to be directly enabled, the mode parameter 4 can also be directly received and configured, so that the target camera sensor can output images according to the image output mode 4. Similarly, after receiving and configuring the mode parameter 4, if it is necessary to switch to enable the drawing mode 3, the target camera sensor can suspend work (stream off), and then receive and configure the mode parameter 3. In this way, the target camera sensor can output images according to image output mode 3.

Obviously, in the above process, regardless of whether the image output mode 3 and the image output mode 4 belong to the same camera mode, the target camera sensor needs to be stream off during the switching process, which will directly affect the fluency of the display screen of the mobile phone. At the same time, Every time you switch, you need to write a large volume of exclusive configuration parameters, and the switch takes longer.

In the embodiment of the present application, as shown in FIG. 13 , the mobile phone configures the image output mode of the target camera sensor and switches the image output mode as follows:

First, the target camera sensor needs to receive public parameters and configure them.

After it is determined that camera mode 1 is enabled, FMC data packet 1 corresponding to camera mode 1 is received and configured. For example, the above-mentioned FMC data packet 1 includes mode parameters of drawing mode a, drawing mode b, and drawing mode c. For the process of configuring the FMC data package 1, reference may be made to S217 in the foregoing embodiments. In the case that image output mode a is the default image output mode of camera mode 1, after the target camera sensor is configured with FMC data package 1, it can output images according to image output mode a.

Afterwards, the target camera sensor can seamlessly switch between image output mode a, image output mode b, and image output mode c according to the change of the shooting scene. For example, receive and load the switch field b corresponding to the output mode b, and output the image according to the output mode b. After outputting the image according to the output mode b, if the switch field c corresponding to the output mode c is received and loaded, the image is output according to the output mode c. Of course, by receiving and loading the switch field a corresponding to the drawing mode a, it is also possible to re-switch to outputting the drawing according to the drawing mode a.

It can be understood that in the same camera mode, the order of seamless switching between multiple output modes can be determined according to the actual shooting scene changes. In the process of switching between any two image output modes, the target camera sensor only needs to receive the switch field of the image output mode to be switched. The data size of the switch field is small, and the receiving and loading speed is fast, which can quickly realize the switching of the image output mode under the same camera mode. In addition, the continuous flow during the switching period will not affect the smoothness of the content displayed on the mobile phone.

After it is determined to switch from camera mode 1 to another camera mode, for example, when it is determined to switch to camera mode 2, the target camera sensor needs to suspend work, that is, stream off is required, and then receive and configure the corresponding FMC data packet 2, including mode parameters of drawing mode d and drawing mode e. Wherein, the above image output mode d and image output mode e are both image output modes supported by camera mode 2, and image output mode d is the default image output mode of camera mode 2.

After configuring the FMC package 2, the target camera sensor can be streamed again. After the target camera sensor is activated, the target camera sensor can output images according to image output mode d.

Afterwards, during the operation of camera mode 2, the target camera sensor can seamlessly switch between the image output mode d and the image output mode e according to the change of the shooting scene. For example, receive and load the switch field e corresponding to the drawing mode e, and output the drawing according to the drawing mode e. After outputting the image according to the outputting mode e, if the switch field d corresponding to the outputting mode d is received and loaded, it can also be switched to outputting the image according to the outputting mode d.

It can be understood that the aforementioned camera mode 1 and camera mode 2 may be any two camera modes in the camera application that support the multi-image output mode. For example, the camera modes that support multiple output modes in the camera application include photo mode, video mode and portrait mode. The above-mentioned camera mode 1 and camera mode 2 may be a photo mode and a video mode, respectively, or a video mode and a portrait mode, or a photo mode and a portrait mode, which are not specifically limited in this embodiment of the present application.

In addition, when the camera sensors corresponding to camera mode 1 and camera mode 2 are not exactly the same, but the target camera sensor is the same, before switching from camera mode 1 to camera mode 2, the target camera sensor may need to be powered off, and Power on again, then accept and configure the public parameters again, and then receive and configure FMC packet 2.

Of course, after the target camera sensor receives and configures the public parameters, if the camera mode 2 needs to be directly enabled, the FMC data packet 2 can also be directly received and configured, so that the target camera sensor can output images according to the output mode d. Afterwards, you can seamlessly switch between the output modes supported by camera mode 2. Similarly, after receiving and configuring the FMC data packet 2, if it is necessary to switch to enable the camera mode 1, the target camera sensor can suspend work (streamoff), and then receive and configure the FMC data packet 1 . In this way, the target camera sensor can output images according to image output mode a. Afterwards, you can seamlessly switch between the output modes supported by camera mode 1.

In the embodiment of the present application, the camera mode supporting multiple drawing modes may also be switched with the camera mode supporting only one drawing mode. As shown in Figure 14, the mobile phone configures the image output mode of the target camera sensor and switches the image output mode as follows:

First, the target camera sensor needs to receive public parameters and configure them.

After the camera mode 2 is determined to be enabled, the FMC data packet 2 corresponding to the camera mode 2 is received and configured. For example, the above-mentioned FMC data packet 2 includes mode parameters of drawing mode d and drawing mode e. For the process of configuring the FMC data package 2, reference may be made to S217 in the foregoing embodiments. In the case that image output mode d is the default image output mode of camera mode 2, after the target camera sensor is configured with FMC data package 2, it can output images according to image output mode d.

Afterwards, the target camera sensor can seamlessly switch between the image output mode d and the image output mode e according to the change of the shooting scene. After it is determined to switch from camera mode 2 to another camera mode, for example, in the case of determining to switch to camera mode 3, the target camera sensor needs to suspend work, that is, needs to stream off. In this example, camera mode 3 is an example of a camera mode that supports only one drawing mode. Then, the mode parameter 5 of the camera mode 3 is received and configured. In this way, the target camera sensor can output images according to the image output mode f indicated by the mode parameter 5.

It can be understood that the above-mentioned camera mode 2 is an example of a camera mode that supports multiple image output modes in the camera application, for example, it may be a camera mode, a portrait mode, and a route mode, etc., which are not specifically limited in this embodiment of the present application.

Of course, after the target camera sensor receives and configures the public parameters, if the camera mode 3 needs to be directly enabled, the mode parameter 5 can also be directly received and configured, so that the target camera sensor can output images according to the output mode f. Similarly, after receiving and configuring the mode parameter 5, if it is necessary to switch to enable the camera mode 2, the target camera sensor can suspend work (stream off), and then receive and configure the FMC data packet 2. In this way, the target camera sensor can output images according to image output mode d. Afterwards, you can seamlessly switch between the output modes supported by camera mode 2.
