Description

Picture resolution configuration method, electronic equipment and storage medium

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method for configuring resolution of a picture, an electronic device, and a storage medium.

Background

With the development of technology, electronic devices (e.g., digital cameras, or mobile phones with cameras, tablet computers, etc.) have been increasingly used for shooting, and the use of electronic devices has become a popular choice.

When a user uses the electronic equipment to shoot, in order to improve the shooting definition of the picture, the user can adjust the resolution of the camera, so that the camera shoots the picture with high-definition quality. However, at present, the electronic device configures the resolution for the camera application, the resolution needs to be acquired and configured from the bottom layer in a cross-process manner, and the time cost is high. How to simplify the process of configuring resolution for camera applications and save time for electronic devices is yet to be further investigated.

Disclosure of Invention

The application provides a picture resolution configuration method, electronic equipment and a storage medium, which simplify the process of configuring resolution for camera application by the electronic equipment and improve the resolution configuration efficiency.

In a first aspect, the application provides a picture resolution configuration method, which comprises the steps of storing a first configuration file in an operation memory of a camera application when the camera application is operated by electronic equipment, recording corresponding relations between a plurality of different shooting parameters and picture resolutions in the first configuration file, receiving and responding to first operation of a user on the camera application by the electronic equipment, acquiring the first configuration file from the operation memory of the camera application by the electronic equipment, acquiring first picture resolution from the first configuration file by the electronic equipment based on the first shooting parameters, acquiring a first image by the electronic equipment through the camera application at the first picture resolution, and displaying the first image in the camera application by the electronic equipment.

Alternatively, the electronic device may display the first image within a preview window of the camera application.

In some embodiments, after the camera application is turned off, the first configuration file stored in the running memory of the camera application is purged. When the camera application is run again, the camera application loads the first configuration file into a running memory of the camera application.

By this method, the electronic device 100 may store resolution information supported by the camera application in the first profile. After the camera application is running, the electronic device 100 stores the first configuration file in a running memory of the camera application. When the camera application needs to reconfigure the picture resolution, the camera application only needs to acquire the updated picture resolution from the first configuration file, so that the process of acquiring the updated picture resolution by the camera application is simplified, and the speed of acquiring the updated picture resolution by the camera application is also increased.

With reference to the first aspect, in a possible implementation manner, after the electronic device runs the camera application, before storing the first configuration file in the running memory of the camera application, the method further includes the electronic device obtaining the first configuration file from a file system of the camera application.

The first configuration file is stored within a file system of the camera application. When the camera application is running, the camera application may obtain the first configuration file from the file system of the camera application and store the first configuration file in the running memory of the camera application.

With reference to the first aspect, in a possible implementation manner, the first shooting parameters include shooting parameters of the camera application in a preview state corresponding to the first shooting mode, after the electronic device acquires the first configuration file, the method further includes the steps that the electronic device acquires second shooting parameters, the second shooting parameters include shooting parameters of the camera application in the shooting state corresponding to the first shooting mode, the electronic device acquires the first configuration file from a running memory of the camera application, and the electronic device acquires the second picture resolution from the first configuration file based on the second shooting parameters.

In other possible implementations, the camera application may not acquire the second picture resolution first, and acquire the second picture resolution after detecting the operation of the shutter key by the user, which is not limited in this aspect of the application.

In this way, the camera application can acquire the second picture resolution in advance before detecting the operation of the user on the shutter key, so as to accelerate the camera application to respond to the operation of the user on the shutter key, thereby improving the user experience.

With reference to the first aspect, in a possible implementation manner, the method further includes the steps of receiving, by the electronic device, a second operation of a shutter key in the camera application by a user, responding to the second operation, acquiring a second image or a second video with a second picture resolution by the electronic device, and storing the second image or the second video by the electronic device.

In this way, the camera application can acquire the second picture resolution in advance before detecting the operation of the shutter key by the user. When the camera application detects the operation of the user on the shutter key, acquiring a second image or a second video with the second picture resolution acquired in advance, so as to accelerate the response of the camera application to the operation of the user on the shutter key, and improve the user experience.

With reference to the first aspect, in one possible implementation manner, the second picture resolution is greater than the first picture resolution.

In general, the user has no high demands on the sharpness of the preview image. The camera application can acquire the preview image with lower picture resolution, and can save power consumption of the electronic device. Nor does it exceed the screen resolution of the electronic device.

With reference to the first aspect, in one possible implementation manner, the first operation includes any one or more of changing a shooting mode of a camera application, changing a display screen state of an electronic device, changing a camera type, and changing a picture scale.

With reference to the first aspect, in one possible implementation manner, before the electronic device receives and responds to the first operation of the user on the camera application, the method further includes the steps that the electronic device obtains a first configuration file from a running memory of the camera application, obtains third shooting parameters, obtains third picture resolution from the first configuration file based on the third shooting parameters, obtains a third image through the camera application at the third picture resolution, and displays the third image in the camera application.

In one possible implementation manner, the third shooting parameters comprise shooting parameters of the camera application in a preview state corresponding to a default shooting mode, the method further comprises the steps that the electronic device obtains fourth shooting parameters, the fourth shooting parameters comprise shooting parameters of the camera application in a shooting state corresponding to the default shooting mode, the electronic device obtains a first configuration file from an operation memory of the camera application, and the electronic device obtains fourth picture resolution from the first configuration file based on the fourth shooting parameters.

In some embodiments, the third picture resolution may be referred to as an initial preview resolution and the fourth picture resolution may be referred to as an initial capture resolution.

Thus, when the camera application is first turned on, the camera application may acquire an initial preview resolution and an initial photographing resolution and acquire a preview image at the initial preview resolution before the user does not change photographing parameters.

Alternatively, the camera application may acquire only the initial preview resolution without acquiring the initial photographing resolution. Upon detecting the user's operation with respect to the shutter key, the camera application reacquires the initial photographing resolution.

Optionally, the camera application may also obtain the initial shooting resolution from the first configuration file based on the initial shooting parameters after obtaining the first configuration file.

With reference to the first aspect, in one possible implementation manner, the electronic device periodically/sporadically obtains a second configuration file from the server, where the second configuration file is partially different or completely different from the first configuration file.

In this way, the first profile of the camera application stored on the electronic device may be updated periodically/sporadically.

In some embodiments, the content of the configuration file is related to the device model. The content of the configuration files corresponding to different device models may be different. In other embodiments, the content of the configuration files corresponding to different device models may be the same, which is not limited in the present application.

With reference to the first aspect, in one possible implementation manner, the shooting parameters include any one or more of shooting status, shooting mode, device display screen status, camera type and picture proportion.

In a fourth aspect, the present application provides a computer program product comprising instructions which, when run on an electronic device, cause the electronic device to perform a picture resolution configuration method as provided in any one of the possible implementations of the first aspect.

In a fifth aspect, the present application provides a chip system, the chip system comprising one or more processors for invoking computer instructions to cause an electronic device to perform a picture resolution configuration method as provided in any one of the possible implementations of the first aspect.

For the description of the advantageous effects of the second aspect to the fifth aspect, reference may be made to the description of the advantageous effects of the first aspect, and the present application will not be repeated here.

First, technical terms related to the present application will be explained

1. Picture scale and picture resolution.

The picture resolution can be obtained by the number of pixels of the picture in the lateral direction and the number of pixels in the vertical direction. For example, a 1920x1080 picture may consist of 1920 pixels in the lateral direction and 1080 pixels in the longitudinal direction.

The picture scale may be obtained by a ratio of the number of pixels in the vertical direction and the number of pixels in the horizontal direction of the picture, for example, 1920x1080 of the picture scale may be 16:9.

A picture scale may correspond to one or more different picture resolutions, one picture resolution corresponding to only one picture scale.

The camera application may support a variety of picture scales, which may include, but are not limited to, 1:1, 4:3, 16:9, full screen, and the like. Wherein, the picture proportion under the full screen can be 21:9, and the picture proportion of different types of electronic devices under the full screen can be different. The application is illustrated with the example that the picture ratio under full screen can be 21:9.

Wherein a picture scale of 1:1 may correspond to one or more different picture resolutions, such as 1080 x 1080, 960 x 960, etc.

A 4:3 picture scale may correspond to one or more different picture resolutions, such as 1440x1920, 1200 x 1600, 960 x 1280, 480 x 640, etc.

A picture scale of 16:9 may correspond to one or more different picture resolutions, such as 1080 x 1920, 900 x 1600, 720 x 1280, 540 x 960, and 360 x 640.

One or more different picture resolutions may be corresponding at full screen picture scale, e.g., 823 x 1920, 463 x 1080, 412 x 960, etc.

Optionally, when the camera application is started for the first time, the camera application default shooting mode is a normal shooting mode.

Alternatively, the same photographing mode may be divided into different photographing states, for example, a normal photographing mode may be divided into a preview state and a non-preview state. The portrait photographing mode may be also classified into a preview state and a non-preview state. The high definition photographing mode may be also classified into a preview state and a non-preview state. Night scene photographing modes can also be classified into preview states and non-preview states. Panoramic photographing modes can also be classified into preview states and non-preview states. Optionally, some photographing modes may not distinguish between a non-preview state and a preview state, which is not limited by the present application.

The video recording mode may include, but is not limited to, any one or more of a normal video recording mode, a delayed video recording mode, a slow motion video recording mode, and the like.

Alternatively, the same recording mode may be divided into different shooting states, for example, a normal recording mode may be divided into a preview state and a non-preview state. The delayed video recording mode may also be divided into a preview state and a non-preview state. The slow motion video mode may be classified into a preview state and a non-preview state. Alternatively, the recording mode may not distinguish between the non-preview state and the preview state, which is not limited by the present application.

Different shooting modes can correspond to one picture proportion, and can also correspond to multiple picture proportions. When a certain shooting mode supports multiple picture scales, a user can select to switch different picture scales.

For example, in the normal photographing mode, the user may select a 1:1 picture ratio for a 4:3 picture ratio.

The inner folding screen can be folded towards the direction facing the A screen and the B screen to form a folding shape with a certain included angle. When the inner folding screen is in the middle folding state, the displayable screens of the folding screen comprise an A screen, a B screen and a C screen. In the middle folding state, the display areas where the screen a and the screen B are located may also be referred to as a large screen, and the display areas where the screen a and the screen B are located may also be referred to as an inner screen. The included angle alpha between the screen A and the screen B is larger than or equal to the angle II and smaller than the angle I. For example, the angle two may take a value between 10 degrees and 170 degrees. For example, when the inner folding screen is in the intermediate folding state, the included angle α between the a screen and the B screen may be 120 degrees.

The folded state of the folding screen shown in fig. 2C may also be referred to as a fully folded state.

The inward folding screen can be continuously folded towards the direction facing the A screen and the B screen. Until the inner folding screen is in a completely folded state.

As shown in fig. 2C, when the inner folding screen is in the fully folded state, the displayable screen of the inner folding screen includes only the C screen. In the fully folded state, the display area where the C-screen is located may also be referred to as a small screen, and the display area where the C-screen is located may also be referred to as an outer screen.

Fig. 3B-3C are schematic views showing display forms of the outer folding screen in a folded state.

The folded state of the folding screen shown in fig. 3B may also be referred to as an intermediate folded state.

The outer folding screen can be folded towards the opposite direction of the screen A and the screen B to form a folding form with a certain included angle. I.e. the folding direction of the outer and inner folds is opposite. When the outer folding screen is in the intermediate state, the displayable screen of the folding screen comprises an A screen and a B screen, and an included angle alpha between the A screen and the B screen is more than or equal to an angle IV and less than or equal to an angle III.

The folded state of the upper and lower folding screens shown in fig. 3F may also be referred to as a fully folded state.

As shown in fig. 3F, when the upper and lower folding screens continue to bend the outer folding screen toward the direction in which the a screen and the B screen face each other in the folded state, the a screen and the B screen of the upper and lower folding screens are hidden from view. When the upper folding screen and the lower folding screen are in a fully folded state, the screen A and the screen B are in a screen-off state, an included angle alpha between the screen A and the screen B is larger than or equal to 0 degree and smaller than an angle IV, and the value of the angle IV can be between 0 degree and 10 degrees.

Illustratively, in some embodiments, the upper and lower folding screens may also include a C screen. The C screen is positioned on the back of the A screen or the B screen. When the upper folding screen and the lower folding screen are in an unfolding state, the C screen is in a screen-extinguishing state. When the upper and lower folding screens are in a folded state, the C screen is in a bright screen state.

Fig. 4 shows a schematic view of a display form of the extension screen.

In some, the extension screen may also be referred to as a scroll screen. The scroll screen of the electronic device may be pulled out or rolled back in a direction perpendicular to the scroll, changing the screen length of the scroll screen perpendicular to the scroll direction.

The morphology of the scroll screen can be divided into an undeployed state, a semi-deployed state, and a fully deployed state. Fig. 4 (a) is a schematic diagram of the undeployed state of the scroll screen. When the scroll screen is in an undeployed state, a part of the screen of the scroll screen is hidden in the body of the electronic device, and the electronic device can display an interface of an application on another part of the screen which is unfolded, and the length of the screen is equal to the length one. The portion of the screen hidden within the body of the scroll screen may be extended in a designated direction (e.g., the direction of the arrow shown in the figure). When the screen of the roll screen has not been fully unwound, the roll screen is in a half-unwound state, as shown in (b) of fig. 4. When the scroll screen is in a semi-unfolding state, part of the screen hidden in the body of the scroll screen is reduced, and part of the screen exposed on the surface of the body of the scroll screen is increased until all the scroll screen is exposed on the surface of the body of the scroll screen. When the roll screen is fully exposed on the surface of the body, the roll screen is in a fully extended state, as shown in fig. 4 (c), where the length of the screen is two. Wherein the second length is greater than the first length. It will be appreciated that when the length of the screen is greater than length one and less than length two, the roller screen is in a semi-extended state.

It should be noted that, in the embodiment of the present application, the scroll screen may be extended along the first direction perpendicular to the scroll, from an undeployed state, through a semi-deployed state, to a fully deployed state. Similarly, the spool screen may be retracted in a second direction perpendicular to the spool from a fully extended position, through a semi-extended position, to an undeployed position. Wherein the first direction and the second direction are opposite.

Alternatively, it is not limited to pulling out in the right direction perpendicular to the horizontal of the scroll of the electronic device. In some embodiments, the scroll screen of the electronic device may also be pulled out in a left direction perpendicular to the scroll horizontal.

Alternatively, in some embodiments, the reel of the electronic device may be located in a horizontal direction, and the electronic device may pull the reel screen vertically above or below the reel, which is not limited by the embodiment of the present application.

The electronic device display screen based on the description above may include a bar display screen, a folding screen, and an expansion screen. The display areas of the display screens of the electronic devices in different forms are different in size, and the proportion of pictures supported by the camera application may be the same or different.

For example, when the electronic device display is a flat panel display, the flat panel display includes only one display state, so for the flat panel display, the picture scale supported by the camera application may be determined, and for example, may include multiple picture scales of 1:1, 4:3, and 16:9.

For another example, when the electronic device display screen is a folding screen, the picture scale supported by the camera application may include multiple picture scales of 1:1, 4:3, and 16:9 when the folding screen is in the folded state shown in fig. 2C or fig. 3C. When the folding screen is in the unfolded state shown in fig. 2A or fig. 3A, the display area of the display screen of the electronic device becomes larger, and the picture proportion supported by the camera application may include multiple picture proportions of 1:1, 8:7, and the like.

For another example, when the electronic device display screen is an extension screen, the picture proportions supported by the camera application may include multiple picture proportions of 1:1, 4:3, and 16:9 when the extension screen is in the folded state shown in (a) of fig. 4. When the expansion screen is in the unfolded state shown in (c) in fig. 4, the display area of the display screen of the electronic device becomes larger, and the picture proportion supported by the camera application may include multiple picture proportions of 1:1, 8:7, and the like.

Fig. 5 shows a schematic diagram of an electronic device 100 configuring picture resolution for a camera application.

S5001, in response to a user operation to start the camera application, the camera application sends a picture resolution configuration request to the HAL layer.

For example, the user operation to open the camera application may be a user operation, such as a click operation, of a user on a camera application icon on the desktop.

In response to a user operation to open the camera application, the camera application sends a picture resolution configuration request to the HAL layer. The request is for obtaining a list of picture resolutions supported by the camera application.

S5002, responding to the picture resolution configuration request, and acquiring a picture resolution list supported by the camera application by the HAL layer.

In response to the picture resolution configuration request, the HAL layer may obtain a list of picture resolutions supported by the camera application.

TABLE 1

Table 1 exemplarily shows that the HAL layer acquires a list of picture resolutions supported by the camera application. As shown in table 1, in the case where the picture ratio is 1:1, the picture resolution may include 1080×1080, 960×960. In the case of a 4:9 picture scale, the picture resolutions may include 1440x1920, 1200 x 1600, 960 x 1280, and 480 x 640. In the case of a picture scale of 16:9, the picture resolution may include 1080×1920, 900×1600, 720×1280, 540×960, and 360×640. In the case of a picture scale of 21:9, the picture resolution may include 823×1920, 463×1080, 412×960.

After the picture resolution list supported by the camera application is acquired, the HAL layer sends the picture resolution list supported by the camera application to the camera application.

S5003, HAL layer sends the picture resolution list to the camera application.

The shooting parameters may include, but are not limited to, icon scale and the like. The picture scale may be, for example, 4:3.

S5004, the camera application screens out a picture resolution from the picture resolution list based on shooting parameters.

The camera application may obtain a picture resolution matching picture 4:3 from the obtained picture resolution list. For example, the camera application typically configures the camera application with the first-matched picture resolution as the picture resolution for no further picture resolution to traverse. For example, the camera application first matches to the picture resolution of 1440x1920 based on a picture scale of 4:3, the camera application may determine 1440x1920 as the final selected picture resolution.

S5005, the camera application sends the matched picture resolution to the HAL layer.

S5006, the HAL layer sends the picture resolution to a camera module for driving, so that the camera module can collect images according to the picture resolution.

After determining the picture resolution, the camera application then sends the matched picture resolution to the HAL layer. The HAL layer sends the picture resolution to the camera module driver, so that the camera module driver can control the camera module to collect images according to the picture resolution.

In some embodiments, after the user changes the shooting parameters of the camera application, for example, after the picture ratio is switched from 4:3 to 16:9, the camera application needs to re-acquire the picture resolution list uploaded by the HAL layer again in the manner shown in fig. 5 and re-match the picture resolution.

As can be seen from the embodiment of fig. 5, the camera application confirms that the picture resolution depends on the picture resolution list supported by the camera application reported by the HAL layer, and the interaction between the camera application and the HAL layer needs to be cross-processed, so that the time for the camera application to acquire the picture resolution is relatively high, and the camera application cannot acquire the picture resolution in time. From the interface display perspective, for example, after the electronic device 100 opens the camera application based on a user operation, the camera application needs to wait for a period of time before the camera preview screen can be displayed. For another example, after the electronic device 100 changes the shooting parameters of the camera application based on the user operation, the camera application also needs to wait for a period of time to display the preview screen based on the updated shooting parameters, which is not good for the user experience.

Based on the analysis, the application provides a picture resolution configuration method, electronic equipment and a storage medium. The method may comprise the steps of:

In step one, the electronic device 100 receives a user operation of starting a camera application, and in response to the user operation, the electronic device 100 obtains a first configuration file and stores the first configuration file in an operation memory of the camera application, wherein the first configuration file records a corresponding relationship between a plurality of picture resolutions supported by the camera application and shooting parameters.

The first configuration file may store the shooting parameters and the picture resolution in a key-value form. The key may refer to a shooting parameter of the camera application, and the value may refer to a picture resolution of the camera application.

The shooting parameters can include, but are not limited to, any one or more of shooting states, shooting modes, device display screen states, cameras, picture proportions and the like.

For the introduction of the first configuration file, reference may be made to the description of the embodiment of fig. 10 to 13, and the description of the present application is omitted here.

Alternatively, the first configuration file may be stored in the disk before the camera application is not started to run, for example, the first configuration file may be stored in a file system corresponding to the camera application in the disk.

Alternatively, the first profile may be associated with a device model. The content of the first profile stored within different device models may be different. In other embodiments, the content of the first configuration file stored in different device models may be the same, which is not limited by the present application.

Step two, the electronic device 100 obtains initial shooting parameters, obtains initial resolution from the first configuration file based on the initial shooting parameters, and the camera application acquires and displays an image with the initial resolution.

In other embodiments, the electronic device 100 may change the photographing parameters based on the user operation. The camera application may obtain updated capture parameters and match the updated resolution from the first profile based on the updated capture parameters. The electronic device 100 may capture an image and display the image based on the updated resolution.

For example, when the temperature reported by temperature sensor 180J exceeds a threshold, electronic device 100 performs a reduction in the performance of a processor located in the vicinity of temperature sensor 180J in order to reduce power consumption to implement thermal protection. In other embodiments, when the temperature is below another threshold, the electronic device 100 heats the battery 142 to avoid the low temperature causing the electronic device 100 to be abnormally shut down. In other embodiments, when the temperature is below a further threshold, the electronic device 100 performs boosting of the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperatures.

The touch sensor 180K, also referred to as a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is for detecting a touch operation acting thereon or thereabout. The touch sensor may communicate the detected touch operation to the application processor to determine the touch event type. Visual output related to touch operations may be provided through the display 194. In other embodiments, the touch sensor 180K may also be disposed on the surface of the electronic device 100 at a different location than the display 194.

The bone conduction sensor 180M may acquire a vibration signal. In some embodiments, bone conduction sensor 180M may acquire a vibration signal of a human vocal tract vibrating bone pieces. The bone conduction sensor 180M may also contact the pulse of the human body to receive the blood pressure pulsation signal. In some embodiments, bone conduction sensor 180M may also be provided in a headset, in combination with an osteoinductive headset. The audio module 170 may analyze the voice signal based on the vibration signal of the sound portion vibration bone block obtained by the bone conduction sensor 180M, so as to implement a voice function. The application processor may analyze the heart rate information based on the blood pressure beat signal acquired by the bone conduction sensor 180M, so as to implement a heart rate detection function.

The motor 191 may generate a vibration cue. The motor 191 may be used for incoming call vibration alerting as well as for touch vibration feedback. For example, touch operations acting on different applications (e.g., photographing, audio playing, etc.) may correspond to different vibration feedback effects. The motor 191 may also correspond to different vibration feedback effects by touching different areas of the display screen 194. Different application scenarios (such as time reminding, receiving information, alarm clock, game, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect may also support customization.

The indicator 192 may be an indicator light, may be used to indicate a state of charge, a change in charge, a message indicating a missed call, a notification, etc.

In the embodiment of the invention, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 7 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present invention.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, from top to bottom, there are an application layer, a hardware abstraction layer HAL, a driver layer, and a hardware layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 7, the application package may include a camera application that includes running memory. After the camera application is running, the electronic device 100 may allocate running memory for the camera application. After the camera application is closed, the running memory of the camera application is then cleared.

In some embodiments, after the camera application is running, the running memory of the camera application may be used to store the first configuration file. After the camera application is closed, the first configuration file stored in the running memory of the camera application is also cleaned.

In some embodiments, an application framework layer may also be included between the application layer and the HAL layer. The application framework layer provides an application programming interface (application programming interface, API) and programming framework for the application of the application layer. The application framework layer includes a number of predefined functions. By way of example, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like. The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc. The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture. The telephony manager is used to provide the communication functions of the electronic device 100. Such as the management of call status (including on, hung-up, etc.). The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like. The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

In some embodiments, a system runtime layer may also be included between the application framework layer and the HAL layer. The system runtime layer may include a plurality of functional modules. Such as surface manager (surface manager), media library (Media Libraries), three-dimensional graphics processing library (e.g., openGL ES), 2D graphics engine (e.g., SGL), etc. The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications. Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The hardware abstraction HAL layer is an interface layer between the application framework layer and the kernel layer, and provides a virtual hardware platform for an operating system.

The hardware abstraction HAL layer can be used for receiving a configuration file acquisition request issued by the camera application and sending the configuration file acquisition request to the disk drive, so that the disk drive can control the disk to acquire a first configuration file and send the first configuration file to the camera application through the HAL layer. The camera application stores the first configuration file in an operation memory of the camera application, the camera application can determine initial preview resolution and initial shooting resolution from the first configuration file based on initial shooting parameters and send the initial preview resolution and the initial shooting resolution to the camera driver through the HAL layer, so that the camera driver can control the camera module to acquire preview images with the initial preview resolution, and when operation of a user on a shutter is monitored, the camera module acquires and images or videos with the initial shooting resolution.

The driver layer is a layer between hardware and software. The driver layer includes drivers for various hardware. The drive layer may include a camera drive, a disk drive, and the like. Wherein the camera drives an image sensor (e.g., image sensor 1, image sensor 2, etc.) for driving one or more cameras in the camera module to capture images and an image signal processor to pre-process the images. The disk drive is used for driving the disk to acquire the first configuration file, the initial preview resolution and the initial shooting resolution.

The hardware layer may include a camera module, a disk, and the like. The camera module may include one or more camera image sensors (e.g., image sensor 1, image sensor 2, etc.) therein. Optionally, a time of flight (TOF) sensor, a multispectral sensor, etc. may be included in the camera module. The disk may include a file system of the camera application having the first configuration file stored therein.

Next, in connection with the interactions between the various layers described above, how the electronic device 100 configures picture resolution for a camera application will be described.

First, it is described how to configure an initial preview resolution and an initial photographing resolution for a camera application when the camera application is first turned on.

1. The camera application obtains a first profile obtaining request and sends the first profile obtaining request to the HAL layer.

In some embodiments, the camera application may also send the first profile acquisition request to the HAL layer through the application architecture layer and the system runtime layer.

2. The HAL layer sends a first profile acquisition request to the disk drive.

3. The disk drive sends a first profile acquisition request to the disk.

After receiving the first configuration file acquisition request sent by the camera application, the HAL layer sends the first configuration file acquisition request to the disk drive, and the disk drive sends the first configuration file acquisition request to the disk. In response to receiving the number of first profile acquisition requests sent by the disk drive, the disk may acquire a first profile from a file system of the camera application.

4. The disk sends the first configuration file to the disk drive.

5. The disk drive sends the first configuration file to the HAL layer.

6. The HAL layer sends the first profile to the camera application.

After the disk acquires the first configuration file, the disk may send the first configuration file to the disk drive. The disk drive then sends the first configuration file to the HAL layer. The HAL layer then sends the first profile to the camera application.

7. The camera application saves the first configuration file in the running memory.

After receiving the first configuration file sent by the HAL layer, the camera application may store the first configuration file in a running memory of the camera application.

8. The camera application obtains an initial preview resolution and an initial shooting resolution from the first configuration file based on the initial shooting parameters.

Wherein the initial photographing parameter is acquired when the camera application is first started, the user operation for starting the camera application may be an input operation, such as a click, for example, as shown in fig. 8A, which acts on the camera application icon. In response to an input operation acting on the camera application icon, the camera application may acquire an initial photographing parameter and an initial photographing resolution.

9. The camera application sends the initial preview resolution to the HAL layer.

10. The HAL layer sends the initial preview resolution to the camera driver.

11. The camera driver sends the initial preview resolution to the camera module.

After the camera application acquires the initial shooting parameters and the initial shooting resolution, the camera application can send the initial preview resolution to the HAL layer, the HAL layer sends the initial preview resolution to the camera driver, and the camera driver sends the initial preview resolution to the camera module.

After receiving the initial preview resolution, the camera module may collect an image based on the initial preview resolution. And displaying the image acquired by the camera module at the initial preview resolution in a preview window of the camera application.

In some embodiments, the camera application may receive a user operation of a shutter key by a user, save a picture or video. In response to a user operation for the shutter key, the camera application may send the initial photographing resolution acquired in advance to the HAL layer, which in turn sends the initial photographing resolution to the camera driver, which sends the initial photographing resolution to the camera module. After receiving the initial shooting resolution, the camera module can acquire images or videos based on the initial shooting resolution. And storing the image or video acquired by the camera module at the initial shooting resolution in a gallery.

In some embodiments, the camera application may receive a user changing a shooting parameter of the camera application. In response to acquiring the updated capture parameters, the camera application needs to acquire an updated preview resolution and an updated capture resolution.

Next, it is described how to configure the camera application with updated preview resolution and updated shooting resolution when the user changes the shooting parameters of the camera application.

12. The camera application receives a first operation of changing shooting parameters by a user, and acquires updated shooting parameters.

13. The camera application obtains a first configuration file from a running memory of the camera application.

14. The camera application obtains updated preview resolution and updated shooting resolution from the running memory based on the updated shooting parameters.

In response to acquiring the updated photographing parameters, the camera application may acquire a first configuration file from a running memory of the camera application. Because the camera application is already running, the running memory of the camera application stores the first configuration file, and the camera application can directly acquire the first configuration file from the running memory of the camera application without acquiring the first configuration file from the file system of the camera application, so that the time for the camera application to acquire the first configuration file can be saved.

After acquiring the updated capture parameters, the camera application may determine an updated preview resolution and an updated capture resolution from the first configuration file based on the updated capture parameters.

15. The camera application sends the updated preview resolution to the HAL layer.

16. The HAL layer sends the updated preview resolution to the camera driver.

17. The camera driver sends the updated preview resolution to the camera module.

After determining the updated preview resolution, the camera application may send the updated preview resolution to the HAL layer, which in turn sends the updated preview resolution to the camera driver, which sends the updated preview resolution to the camera module.

After the camera module receives the updated preview resolution, the camera module can acquire images based on the updated preview resolution. And displaying the camera module in a preview window of the camera application to update the image captured at the preview resolution.

In some embodiments, the electronic device may receive a user operation for a shutter key, save a picture or video. In response to a user operation for the shutter key, the camera application may send the updated photographing resolution acquired in advance to the HAL layer, which in turn sends the updated photographing resolution to the camera driver, which sends the updated photographing resolution to the camera module.

After receiving the updated shooting resolution, the camera module can acquire images or videos based on the updated shooting resolution. And the camera module is used for updating the image or video acquired by the shooting resolution and storing the image or video in a gallery. In this way, the camera application can be accelerated to respond to the shooting action of the user.

First, a resolution configuration scenario provided by the present application will be described.

1. The camera application is started and the electronic device 100 configures a picture resolution for the camera application based on the initial photographing parameters.

In some embodiments, after the electronic device 100 starts the camera application based on user operation, the camera application enters a photographing mode by default.

Fig. 8A-8B show schematic diagrams of the electronic device 100 starting a camera application.

As shown in fig. 8A, the electronic device 100 may display a desktop in which a page with application icons is displayed, the page including a plurality of application icons (e.g., a setup application icon, an application marketplace application icon, a gallery application icon, a browser application icon, etc.). Page indicators are also displayed below the application icons to indicate the positional relationship between the currently displayed page and other pages. A tray area is displayed below the page indicator. The tray area includes a plurality of tray icons, such as a camera application icon, an address book application icon, a phone application icon, and an information application icon. The tray area remains displayed while the page is switched. In some embodiments, the page may also include a plurality of application icons and page indicators, which may not be part of the page, but may exist alone, and the tray icon may also be optional, which is not a limitation of the embodiments of the present application.

The electronic device 100 may receive user input (e.g., a single click) on the camera application icon, and in response to the input operation, the electronic device 100 may display a user interface as shown in fig. 8B. Fig. 8B is a user interface, also referred to as a preview interface, of a photographing and displaying service provided by the electronic device 100 according to an embodiment of the present application.

As shown in fig. 8B, the preview interface may include a mode bar 501, a capture control 502, a preview window 503, a review control 504, a shortcut area 505, and a focus adjustment option 506.

The mode field 501 may include a plurality of shooting mode options, such as "slow motion", "delayed shooting", "portrait", "photograph", "video", "night view", "panoramic", and so on. Different shooting modes can provide shooting services with different effects for users. The user can select any shooting mode of a plurality of shooting modes to shoot according to different requirements. For example, "take a picture" may be a default shooting mode for taking a picture. "video recording" is used to record video. The "night scene" mode is suitable for use in a dark-lit shooting scene, such as at night. The "portrait" mode is suitable for shooting scenes in which the subject is a person. The electronic device 100 may also provide more shooting modes, such as "large aperture", "movie", "professional", etc., which are not illustrated here.

The electronic apparatus 100 may detect a user operation acting on the photographing mode option in the mode field 501 and change the currently used photographing mode according to the user operation. Such as a left/right slide operation. For example, when the drag mode field 5011 is detected to slide to the left (left slide operation) and the buoy is caused to stop at the "portrait" option, the electronic apparatus 100 may switch to the "portrait" mode. By default, the electronic device 100 first uses a "photo" mode.

The photographing control 502 is used to trigger photographing. The electronic device 100 can detect whether there is a user operation, such as a click operation, acting on the capture control 502. Upon detecting a user operation on the photographing control 502, the electronic device 100 may generate a photographing instruction. The electronic device 100 may obtain the image reported by the corresponding timestamp camera according to the photographing instruction, and then store the image as a photograph.

The preview window 503 may be used to display the image reported by the camera in real time. In different shooting modes, the electronic device 100 can process the image reported by the camera, so as to improve the display effect of the image. For example, in a "portrait" mode, the electronic device 100 may blur the background in the image reported by the camera to highlight the portrait. Here, the preview window 503 may display the image processed by the image processing algorithm corresponding to the different photographing modes in real time, so that the user may perceive the photographing effects corresponding to the different photographing modes in real time.

Review control 504 may be used to view thumbnail images of the photos/videos that have been taken. Upon detecting a user operation on the review control 504, the electronic device 100 can also display the best photo corresponding to the thumbnail.

Shortcut function area 505 may include a main angle video mode control 505A, AI scene identification control 505B, a flash control 505C, a color mode control 505D, a setup control 505E, and the like. The control 505A of the corner video mode may be used to trigger the electronic device 100 to identify a corner person of a plurality of persons in the preview screen when turned on. The AI-scene recognition control 505B can be used to trigger the electronic device 100 to recognize a shooting scene in a preview screen when turned on, with the current AI-scene recognition control 505B in an off state. Flash control 505C may be used to trigger electronic device 100 to turn a flash on or off. Color mode control 505D may be used to trigger electronic device 100 to process images captured by a camera using color filters. The settings control 505E may be used to set shooting parameters (e.g., image size, storage format of the image, etc.) of the electronic device 100, and so on.

A plurality of zoom magnification options are shown in focus adjustment option 506. Such as a 0.5x zoom magnification option, a 1x zoom magnification option, a 2.5x zoom magnification option, a 10x zoom magnification option, and the like. The current zoom magnification is 1x. Displayed in the preview window 503 is an image frame captured by the electronic device 100 at a zoom magnification of 1×.

The picture resolution shown in fig. 8B is, for example, 4:3.

In some implementations, after electronic device 100 responds to user input for the camera application icon, before electronic device 100 displays the preview interface shown in fig. 8B, electronic device 100 may obtain the preview resolution in the preview mode, the image displayed within preview window 503 in fig. 8B being the image captured by electronic device 100 at the preview resolution.

In some embodiments, after the electronic device 100 responds to the user input for the camera application icon, the electronic device 100 may obtain a photographing parameter and obtain a photographing resolution in the normal photographing mode based on the photographing parameter. In this way, upon detecting a user operation on the photographing control 502, the electronic device 100 may acquire image frames based on photographing resolution acquired in advance to accelerate the photographing action of the electronic device 100 in response to the user.

Optionally, the preview resolution is lower than the capture resolution. In this way, the electronic device 100 may capture the preview image at a lower resolution to reduce power consumption of the electronic device 100.

Alternatively, the preview resolution may be the same as the shooting resolution, which is not limited in the present application.

In some embodiments, upon detecting a user operation (e.g., a click) of the user with respect to the capture control 502, the electronic device 100 may, in response to the user operation, capture an image at a pre-configured capture resolution and save the image in a gallery.

Fig. 9 shows a flowchart of a method for configuring a picture resolution for a camera application by the electronic device 100 after the camera application is turned on.

The method may be implemented based on interaction between an application layer (e.g., camera application) within the electronic device, a hardware abstraction layer (hardware abstract layer, HAL), a driver layer, and a hardware layer, wherein the application layer is primarily related to the camera application. The drive layer is mainly related to camera drive and disk drive. The hardware layer mainly relates to a camera module, a magnetic disk and the like.

S901, the camera application receives a user operation to start the camera application.

For example, the user operation to open the camera application may be an input, such as a click, shown in fig. 8A, acting on the camera application icon.

S902, in response to a user operation of starting the camera application, the camera application sends a first profile acquisition request to the HAL layer.

S903, the HAL layer sends a first configuration file acquisition request to the disk drive.

S904, the disk drive sends a first configuration file acquisition request to the disk.

In response to a user operation to open the camera application, the electronic device 100 may acquire a first profile acquisition request.

In response to acquiring the first profile acquisition request, the camera application may send the first profile acquisition request to the HAL layer, which in turn sends the first profile acquisition request to the disk drive, which in turn sends the first profile acquisition request to the disk.

S905, the disk acquires the first configuration file based on the first configuration file acquisition request.

In response to receiving the first configuration file sent by the disk drive, the disk may obtain the first configuration file from a file system of the camera application.

S906, the disk sends the first configuration file to the disk drive.

S907, the disk drive sends the first configuration file to the HAL layer.

S908, HAL layer sends the first configuration file to the camera application.

After the disk acquires the first configuration file, the disk may send the first configuration file to the disk drive, and the disk drive sends the first configuration file to the HAL layer, which sends the first configuration file to the camera application.

The composition of the first profile is described next.

The first configuration file records the corresponding relation between a plurality of different shooting parameters and picture resolution.

In some embodiments, the file format of the first configuration file may be a JSON file format, and the first configuration file may store the shooting parameters and the picture resolution in a key-value form, where a key may refer to a shooting parameter of a camera application, and a value may refer to a picture resolution of the camera application.

The shooting parameters may include, but are not limited to, any one or more of a shooting status, a shooting mode, a device display status, a camera type, a picture scale, etc.

The shooting status may include, but is not limited to, a preview status and a non-preview status. The preview state may refer to a state of the camera application before the electronic device 100 receives the click of the shooting control 502 by the user, that is, before the electronic device 100 has shot a picture or has not shot a video yet, or may refer to a state of the camera application after the electronic device 100 receives the click of the shooting control 502 by the user and the electronic device 100 acquires the picture or the video. The non-preview state is the state opposite to the preview state, and may refer to a state that the camera applies when the electronic device 100 receives a click of the photographing control 502 from the user, that is, when the electronic device 100 starts photographing a picture or starts photographing a video.

The photographing mode is a photographing mode that can be provided by a camera application, and may include a photographing mode and a recording mode.

Alternatively, when the camera application is started for the first time, the camera application default shooting mode is a normal shooting mode, and the shooting mode shown in fig. 8B is the normal shooting mode.

The device display status may be for a folded screen or an expanded screen, and the device display status may include a folded state or an expanded state. In some embodiments, if the display of the electronic device 100 is a flat panel display, the shooting parameters may not include the device display status.

The camera types may include front cameras and rear cameras. The front camera or the rear camera may also comprise one or more cameras. For example, the rear camera may include three cameras, such as a main camera, a wide angle camera, a tele camera, and the like. The front camera may comprise a main camera. In other embodiments, the front camera may also include multiple cameras, for example, the front camera may also include a wide angle camera, and the application is not limited thereto.

In some embodiments, the camera application may determine the camera type from a plurality of rear cameras or from a plurality of front cameras based on the current zoom magnification.

Illustratively, when the rear-facing camera includes a main camera, a wide-angle camera, and a telephoto camera, the three rear-facing cameras support different zoom resolutions. For example, the zoom magnification supported by the main camera is between Ax and Bx, the zoom magnification supported by the telephoto camera is larger than Bx, and the zoom magnification supported by the wide-angle camera is smaller than Ax. Bx is greater than Ax. Which camera is used by the current camera application may be determined based on the current zoom magnification of the camera application.

Illustratively, A may be 1 and B may be 5. The zoom magnification supported by the main camera is between 1x and 5x, the zoom magnification supported by the long-focus camera is larger than 5x, and the zoom magnification supported by the wide-angle camera is smaller than 1x. When the currently selected zoom magnification of the camera application is 1x, it can be determined that the camera application uses the main camera. When the currently selected zoom magnification of the camera application is 10x, it can be determined that the camera application uses a tele camera.

The camera application can determine the type of the camera based on other information as well as the type of the camera based on the zoom magnification, which is not limited in the application.

The picture scale may be associated with a capture mode, and different capture modes may support different picture scales. For example, the normal photographing mode may provide a picture ratio of 1:1, a picture ratio of 4:3, a picture ratio of 16:9, and the like. The normal video mode may only provide a picture scale of 16:9. The proportion of pictures supported by different shooting modes can be related to equipment manufacturers, and the proportion is preset before the equipment leaves the factory.

In some embodiments, the shooting parameters may also include other information, which is not limited in this regard by the present application.

In order to facilitate understanding of the composition structure of the configuration file, the present application describes the composition structure of the configuration file by taking a normal photographing mode and a normal video recording mode as examples.

Fig. 10 is a schematic diagram of a configuration file corresponding to a normal photographing mode.

As shown in fig. 10, the normal photographing mode may be divided into two branches, a preview state and a non-preview state, respectively.

Alternatively, the resolution of the picture in the preview mode and the non-preview mode may be different in the normal photographing mode.

Illustratively, when the camera application is in the normal photographing mode, the normal photographing mode is in the preview state before the photographing of the picture is started, the camera application may acquire the preview resolution in the preview state, and the image displayed in the preview window 503 in fig. 8B is the image acquired by the electronic device 100 at the preview resolution. After starting taking a picture, the electronic device 100 may acquire a photographing resolution in the non-preview mode.

In some embodiments, the preview resolution in the preview state may be less than the capture resolution in the non-preview mode, and the electronic device 100 may capture and display the preview image at a lower resolution to save power consumption of the electronic device 100.

As shown in fig. 10, the normal photographing mode can be divided into two branches of a preview state and a non-preview state. When the camera is in a preview state or a non-preview state, the resolution of the picture can be determined based on the device display screen state, the camera type and the currently selected picture proportion.

It should be noted that, when the display screen of the electronic device 100 is a straight panel screen, but not a folded screen or an extended screen, the configuration file corresponding to the normal photographing mode shown in fig. 10 may not be divided into an unfolded state and a folded state.

In some embodiments, while the camera application is in the normal photographing mode and in the non-preview state, the electronic device 100 may determine the preview resolution based on the device display screen state, the camera type, and the picture scale.

For example, after the electronic device 100 responds to user input for the camera application icon, the camera application is in a normal photographing mode and in a non-preview state before the electronic device 100 receives user operation of the photographing control 502 by the user. The electronic device 100 may obtain current photographing parameters.

For example, in the case where the photographing parameters include a normal photographing mode, a non-preview state, a folded state, and a rear-mounted main camera, and the picture ratio is 1:1, the electronic device 100 may determine that the picture resolution is 1920x1920.

For example, in the case where the photographing parameters include a normal photographing mode, a non-preview state, a folded state, and a rear-mounted main camera, and the picture ratio is 4:3, the electronic device 100 may determine that the picture resolution is 1440x1920.

For example, in the case where the photographing parameters include a normal photographing mode, a non-preview state, a folded state, and a rear-mounted main camera, and the picture ratio is 16:9, the electronic device 100 may determine that the picture resolution is 1080×1920.

For example, in the case where the photographing parameters include a normal photographing mode, a non-preview state, a folded state, and a rear-mounted tele camera, and the picture ratio is 1:1, the electronic device 100 may determine that the picture resolution is 1660×1660.

For example, in the case where the photographing parameters include a normal photographing mode, a non-preview state, a folded state, and a rear-mounted tele camera, and the picture ratio is 4:3, the electronic device 100 may determine that the picture resolution is 1200×1600.

The resolution of the picture shown in fig. 10 is only for explaining the present application, and other values are also possible, which is not limited by the present application.

In some embodiments, the configuration files corresponding to other photographing modes may be the same as the configuration files corresponding to the common photographing modes, and only the configuration files corresponding to the common photographing modes may be reserved in the first configuration file, so that the configuration files corresponding to the common photographing modes may be shared by the other photographing modes and the common photographing modes.

For example, the other photographing modes may be a portrait photographing mode, as shown in fig. 11, and the root node is a portrait photographing mode and a normal photographing mode, which may share a configuration file. In this way, the data volume of the first profile can be reduced.

For the description of the configuration file shown in fig. 11, reference may be made to the description in the embodiment of fig. 10, and the description of the present application is omitted here.

In other embodiments, the video mode may also support other cameras, such as a wide-angle camera and a tele camera, which is not limited in this regard.

As shown in fig. 12, the normal video mode can be divided into two branches, i.e., a preview state and a non-preview state.

Alternatively, the picture resolution in the preview mode and the non-preview mode may be different in the normal video mode.

For example, when the camera application is in the normal recording mode, the normal recording mode is in the preview state before starting recording, the camera application may acquire the preview resolution in the preview state, and after starting recording, the electronic device 100 may acquire the photographing resolution in the non-preview mode.

As shown in fig. 12, the normal video recording mode can be divided into two branches, i.e., a preview state and a non-preview state. When the camera is in a preview state or a non-preview state, the resolution of the picture can be determined based on the device display screen state, the camera type and the currently selected picture proportion.

Note that, when the display screen of the electronic device 100 is a bar screen, rather than a folded screen or an extended screen, the configuration file corresponding to the normal video recording mode shown in fig. 11 may not be divided into an unfolded state and a folded state.

In some embodiments, while the camera application is in normal video mode and in a non-preview state, the electronic device 100 may determine the preview resolution based on the device display screen state, the camera type, and the picture scale.

In some embodiments, the configuration files corresponding to other video modes may be the same as the configuration files corresponding to the normal video modes, and only the configuration files corresponding to the normal video modes may be reserved in the first configuration file, and the configuration files corresponding to the normal video modes may be shared by other video modes and the normal video modes.

For example, the other recording mode may be a delayed recording mode, as shown in fig. 13, the root node is a delayed recording mode and a normal recording mode, and the delayed recording mode and the normal recording mode may share a configuration file. In this way, the data volume of the first profile can be reduced.

For the description of the configuration file shown in fig. 13, reference may be made to the description in the embodiment of fig. 12, and the description of the present application is omitted here.

The application takes the common photographing mode and the common video mode as examples to describe the composition structure of the configuration files, and the composition structure of the configuration files of other photographing modes can be similar to the composition structure of the configuration files of the common photographing mode or the common video mode, and the application is not repeated here.

Alternatively, the configuration files corresponding to the plurality of shooting modes may be a complete file, for example, the configuration file of the normal shooting mode and the configuration file of the normal video mode may be stored in one file, and the configuration file corresponding to each shooting mode may also be a separate file, for example, the configuration file of the normal shooting mode and the configuration file of the normal video mode may be stored in two different files respectively.

Alternatively, the configuration files of fig. 10-13 are also merely used to illustrate the present application, and are not meant to be limiting.

S909, the camera application stores the first configuration file in the running memory of the camera application.

Optionally, after the electronic device 100 closes the process of the camera application, the electronic device 100 clears the first configuration file stored in the running memory of the camera application. After the camera application is turned on again, the electronic device 100 loads the first configuration file into the running memory of the camera application again.

In some embodiments, if the user who opens the camera application operates to switch the camera application running in the background to the foreground, the first configuration file is already stored in the running memory of the camera application, and the camera application may directly obtain the first configuration file from the running memory of the camera application.

S910, the camera application acquires the initial preview resolution and the initial shooting resolution from the first configuration file based on the initial shooting parameters.

For example, if the user operation of opening the camera application is the first user operation of opening the camera application, after the electronic device 100 enters the camera application, the camera application may default to the normal photographing mode, and the electronic device 100 may display the user interface shown in fig. 8B. The electronic device 100 may acquire initial photographing parameters corresponding to the normal photographing mode.

Exemplary initial capture parameters may include, but are not limited to, normal capture mode, preview state, collapsed state, rear-mounted main camera, and 4:3 picture scale.

Wherein, the shooting state in the initial shooting parameters used for acquiring the initial preview resolution may be a preview state. The photographing state in the initial photographing parameters used to acquire the photographing preview resolution may be a non-preview state.

For how the electronic device 100 obtains the picture resolution based on the shooting parameters, reference may be made to the description in the embodiment of fig. 10 below. The present application is not described in detail herein.

The first configuration file comprises a plurality of picture resolutions corresponding to different shooting parameters. The first configuration file may be preset within a file system of the camera application. For example, the first profile may be preset in a file system of the camera application before the electronic device 100 leaves the factory, and the first profile in the file system of the camera application may also be periodically/sporadically acquired and updated from the server by the electronic device 100.

In some embodiments, the initial shooting resolution may not be required to be confirmed first, and the initial shooting resolution may be confirmed after the camera application receives the input operation of the user for the shutter key.

In this way, the camera application determines the initial photographing resolution in advance, and upon detecting a user operation acting on the photographing control 502, the electronic device 100 may acquire an image based on the initial photographing resolution acquired in advance to accelerate the photographing action of the electronic device 100 in response to the user.

S912, HAL layer sends the initial preview resolution to the camera driver.

S913, the camera driver sends the initial preview resolution to the camera module.

S914, the camera module collects images with the initial preview resolution.

After receiving the initial preview resolution, the initial shooting resolution and the first configuration file sent by the HAL layer, the camera application can send the initial preview resolution to the HAL layer, and then the HAL layer sends the initial preview resolution to a camera driver, and the camera driver sends the initial preview resolution to the camera module.

S915, the camera application receives a user operation for the shutter key.

S916, the camera application sends the initial photographing resolution to the HAL layer.

S917, HAL layer sends the initial shooting resolution to the camera driver.

S918, the camera driver sends the shooting preview resolution to the camera module.

S919, the camera module collects an image or video with an initial shooting resolution and stores the image or video.

In some embodiments, the electronic device 100 may receive a user operation for a shutter key, save a picture or video.

For example, the user operation for the shutter key may be an input operation for the photographing control 502 in fig. 8B, such as a click.

In response to a user operation for the shutter key, the camera application may send the initial photographing resolution acquired in advance to the HAL layer, which in turn sends the initial photographing resolution to the camera driver, which sends the initial photographing resolution to the camera module.

After receiving the initial shooting resolution, the camera module can acquire images or videos based on the initial shooting resolution. And storing the image or video acquired by the camera module at the initial shooting resolution in a gallery.

In some embodiments, S914-S918 may not be performed, as the application is not limited in this regard.

2. The electronic device 100 changes the photographing parameters of the camera application based on the user operation, and the electronic device 100 needs to acquire updated preview resolution.

In some embodiments, the electronic device 100 may change the shooting parameters of the camera application. After the electronic device 100 changes the shooting parameters of the camera application, the electronic device 100 needs to acquire updated preview resolution.

As can be seen from the above description, the shooting parameters may include, but are not limited to, any one or more of a shooting status, a shooting mode, a device display status, a camera type, a picture scale, and the like. The user may change the shooting mode or change the device display state or change the camera type or change the picture scale to get updated shooting parameters so that the electronic device 100 may obtain updated preview resolution based on the updated shooting parameters.

Several implementations of changing the shooting parameters of a camera application are described next.

Mode one, changing the shooting mode to change the shooting parameters of the camera application.

In the case where the electronic apparatus 100 changes the photographing mode based on the user operation, the electronic apparatus 100 may change photographing parameters of the camera application.

For example, the user operation may switch the normal photographing mode to the normal recording mode. In response to the camera application switching to the normal recording mode, the electronic device 100 may acquire photographing parameters of the normal recording mode.

The shooting parameters of the normal video mode may be different from or the same as those of the normal shooting mode.

After acquiring the shooting parameters of the normal video mode, the electronic device 100 may acquire an updated preview resolution from the configuration file corresponding to the normal video mode based on the shooting parameters of the normal video mode, where the updated preview resolution may be a preview resolution corresponding to the normal video mode.

Exemplary shooting parameters of the normal video mode include, but are not limited to, normal video mode, preview state, folded state, rear main camera and 16:9 picture scale. And based on the shooting parameters, obtaining an updated preview resolution corresponding to the common video mode from the first configuration file, wherein the updated preview resolution may be 810x1440, for example. For how the electronic device 100 obtains the updated preview resolution based on the photographing parameters, reference may be made to the description in the embodiment of fig. 10.

After acquiring the updated preview resolution, the electronic device 100 may capture an image and display a preview image frame based on the updated preview resolution.

In some embodiments, the electronic device 100 also needs to obtain an updated shooting resolution corresponding to the normal video mode. In this way, when detecting the user operation on the photographing control 502, the electronic device 100 may acquire the image frame based on the updated photographing resolution corresponding to the normal video recording mode acquired in advance, so as to speed up the response of the electronic device 100 to the photographing action of the user.

For example, the electronic device 100 may obtain shooting parameters for obtaining updated shooting resolution, including but not limited to a normal video mode, a non-preview state, a collapsed state, a rear-mounted main camera, and a picture scale of 16:9. And obtains the shooting resolution corresponding to the common video recording mode from the first configuration file based on the shooting parameter, and the updated preview resolution may be 1215x2160, for example. For how the electronic apparatus 100 acquires the photographing resolution based on the photographing parameters, reference may be made to the description in the embodiment of fig. 10.

Optionally, the update preview resolution is lower than the update capture resolution. In this way, the electronic device 100 may capture the preview image at a lower resolution to reduce power consumption of the electronic device 100.

Alternatively, the updated preview resolution may be the same as the updated shooting resolution, which is not limited in the present application.

In other embodiments, the electronic device 100 may also determine the updated shooting resolution corresponding to the normal video recording mode after detecting the user operation acting on the shooting control 502, which is not limited in the present application.

In some embodiments, after detecting a user operation (such as clicking) of the shooting control 502 by the user, the electronic device 100 may respond to the user operation to record a video with an updated shooting resolution corresponding to a normal recording mode configured in advance, and store a video file obtained by shooting in a gallery. The electronic device 100 may be expedited in response to the user's shooting actions. After the electronic device 100 receives the user operation of the user on the shooting control 502 again, the camera application stops recording, and the electronic device 100 continues to collect and display the preview image frames with the updated preview resolution corresponding to the normal recording mode.

And the shooting mode is not changed in the second mode so as to change shooting parameters of camera application.

In some embodiments, the shooting parameters of the camera application may also be changed without the electronic device 100 changing the shooting mode.

For example, in the same shooting mode, the electronic device 100 may change the state of the display screen of the electronic device and/or change the type of camera and/or change the proportion of the picture, etc. based on the user operation, and may change the shooting parameters of the camera application to obtain the updated preview resolution.

The application is described by taking other shooting parameters corresponding to the common shooting mode as an example under the condition of not changing the common shooting mode.

In the case where the electronic device display is a folding screen or an expansion screen, the user may change the state of the electronic device display. For example, switching the electronic device display from a folded state to an unfolded state, or switching the electronic device display from an unfolded state to a folded state.

For example, in the normal photographing mode, the electronic device 100 may switch the electronic device display screen state from the folded state to the unfolded state based on the user operation.

In response to the electronic device display screen state being switched from the folded state to the unfolded state, the electronic device 100 may obtain updated photographing parameters of the normal photographing mode.

The updated photographing parameters of the normal photographing mode may be different from or the same as those of the normal photographing mode.

After acquiring the updated shooting parameters of the normal shooting mode, the electronic device 100 may acquire the updated preview resolution from the configuration file corresponding to the normal shooting mode based on the updated shooting parameters of the normal shooting mode, where the updated preview resolution may be the updated preview resolution corresponding to the normal shooting mode.

In other embodiments, the electronic device 100 may also determine the updated shooting resolution corresponding to the normal shooting mode after detecting the user operation on the shooting control 502, which is not limited in the present application.

In some embodiments, after detecting a user operation (e.g., clicking) of the user on the photographing control 502, the electronic device 100 may respond to the user operation to photograph with an updated photographing resolution corresponding to a common photographing mode configured in advance, and store a picture obtained by photographing in a gallery. The electronic device 100 may be expedited in response to the user's shooting actions. After the picture is acquired, the camera application stops photographing and enters the preview state again, and the electronic device 100 continues to acquire and display the preview image frame with the updated preview resolution corresponding to the normal photographing mode.
