It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

In the related art, a display device can be used to frame a target object (e.g., a person) to generate an image. However, in the case of a poor framing environment (e.g., dim light), the image generated by the display device has a poor display effect (e.g., the face is dark and blurry). Some solutions use algorithms to increase the brightness of the face, but the frame rate of the image is low and may produce a jello effect. At the same time, the use of algorithms will increase the noise of the image, requiring noise reduction processing, increasing the workload of the GPU, and there are problems such as a large number of computing resources and low processing efficiency.

The embodiment of the present application provides a display control method, which controls the display output of the display screen by obtaining the first image parameter of the target object in the imaged image, so as to adjust the image parameter of the target object in the imaged image from the first image parameter to the second image parameter. On the one hand, since the presentation effect of the target object under the second image parameter is better than the presentation effect under the first image parameter, the display effect of the imaged image is optimized and the user experience is improved; on the other hand, by controlling the display output of the display screen to adjust the image parameters of the imaged image, compared with processing the imaged image by the algorithm, while reducing the noise on the imaged image, it also saves the computing resources of the GPU, thereby improving the processing efficiency of the imaged image. The method provided by the embodiment of the present application can be performed by an electronic device, wherein the electronic device can be a laptop, a tablet computer, a desktop computer, a set-top box, a mobile device (e.g., a mobile phone, a portable music player, a personal digital assistant, a dedicated messaging device, a portable gaming device) and other various types of terminals, and can also be implemented as a server. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), as well as big data and artificial intelligence platforms.

A light-emitting component refers to a physical device or structure that can emit light. The light-emitting component can be any suitable component, for example, a light-emitting diode (LED), an organic light-emitting diode (OLED), etc. LED is a commonly used light-emitting device that emits light by releasing energy through the recombination of electrons and holes.

In some embodiments, the process of adjusting the image parameter of the target object in the imaged image from the first image parameter to the second image parameter using the display screen may be triggered by a target operator, who may be a local device user or a remote interactive device user.

In some embodiments, adjusting the image parameters of the imaged image from the first image parameter to the second image parameter may be by increasing the brightness of the imaged image for fill light, or by adjusting the color temperature of the imaged image, or by adjusting the shadow of the imaged image, etc.

In some embodiments, the presentation effect of the target object under the second image parameters is better than that under the first image parameters, which may mean that the image quality, clarity, brightness, color temperature, hue, etc. of the target object under the second image parameters better meets the needs of the target object.

The framing scene can be any suitable scene, for example, an office scene, a meeting scene, an outdoor scene, etc. In some embodiments, a mapping relationship between an imaged image and a framing scene can be established. After the imaged image is generated, the framing scene corresponding to the imaged image can be determined according to the mapping relationship.

The process of adjusting the display output of the display screen based on the compensation parameters may refer to the specific implementation of the aforementioned step S121.

In the implementation manner of the present application, the compensation parameters are determined by the difference information between the first image parameters and the target image parameters, the target adjustment requirements, and the difference between the first environmental parameters and the target environmental parameters, which enriches the method of determining the compensation parameters and improves the accuracy of the compensation parameters.

In some embodiments, the step of “adjusting the display output of the display screen based on the compensation parameter” in steps S121a to S121c includes at least one of steps S21 to S24, wherein:

Step S21, based on the compensation parameters, adjust the display screen from including only the first display area to including a second display area and a third display area, wherein the third display area is connected to at least one edge of the second display area, the second display area is used to output display data of the first display area, and the third display area is used to output display data matching the compensation parameters.

FIG2 is a schematic diagram of a display area provided in an embodiment of the present application. As shown in FIG2 , in 2a, the display screen only includes a first display area 201. In 2b, the display screen includes a second display area 202 and a third display area 203, wherein the third display area 203 is arranged outside the second display area 202, and the second display area 202 is arranged inside the third display area 203.

The display data in the first display area may be any appropriate data, for example, imaging image data, interface data of other applications, and the like.

In some implementations, the display data in the first display area may also include, but is not limited to: preview images, video streams, desktop data, and the like.

Step S22: adjusting the display parameters of the first display area of the display screen from the current first display parameters to the second display parameters based on the compensation parameters, or adjusting the display parameters of the third display area of the display screen from the current third display parameters to the fourth display parameters.

Here, the display parameters (including the first display parameters and other display parameters) may be any appropriate parameters, such as brightness parameters, color parameters, detail parameters, and the like.

The method for determining the second display parameter may include but is not limited to: the first sum value, weighting/logarithm/indexing of the first sum value, etc. The first sum value is the sum value of the first display parameter and the compensation parameter.

The method for determining the fourth display parameter may include but is not limited to: the second sum value, weighting/logarithm/indexing of the second sum value, etc. The second sum value is the sum value of the third display parameter and the compensation parameter.

In some implementations, the display parameters of the first display area of the display screen may be adjusted from the current first display parameters to the second display parameters; and then the first display area may be adjusted to include the second display area and the third display area.

In some implementations, after the first display area is adjusted to include the second display area and the third display area, the display parameter of the third display area of the display screen may be adjusted from the current third display parameter to a fourth display parameter.

In some embodiments, when the display parameters of the third display area of the display screen are adjusted from the current third display parameters to the fourth display parameters, the display parameters of the second display area of the display screen can be simultaneously adjusted from the current fifth display parameters to the sixth display parameters, thereby enhancing the display effect of the second display area.

As shown in Figure 3, the display screen includes a second display area 202 and a third display area 203. The third display area 203 is arranged outside the second display area 202. By adjusting the display parameters of the third display area 203, the display effect of the second display area 202 is enhanced.

Step S23: switching the first display output content currently displayed and outputted by the display screen to the second display output content based on the compensation parameter, wherein the first display output content is associated or not associated with the second display output content.

Here, the first display output content may be any appropriate content, such as an image, interface content of other applications, etc. The first display output content may be static content or dynamic content.

The second display output content may be any appropriate content, such as an image, interface content of other applications, etc. The second display output content may be static content or dynamic content.

In some embodiments, the first display output content can be switched to the content-related second display output content. For example, in a conference scenario, the dynamic imaging image can be switched to the static interface content of other applications to improve the ambient brightness. Exemplarily, the dynamic imaging image can be a video image, and the interface content of other applications can be the static interface content of a presentation (PowerPoint, PPT).

In some implementations, switching the first display output content to the second display output content may be switching the background or theme color of the display output content. The theme color may be any suitable color, such as white, yellow, and the like.

In some embodiments, switching the first display output content to the second display output content may be switching the interface content of other applications to preset content. The other applications may be any suitable applications, such as chat applications, video applications, etc. The preset content may be any suitable content, such as desktop content, preset images, etc. In some embodiments, the preset content may be enlarged and displayed to switch the first display output content to the second display output content.

Step S24, based on the compensation parameters, the display screen is switched from the current first display output mode to the second display output mode to adjust the display layout of the target window interface on the display screen, wherein the target window interface includes a preview interface of the imaging image and/or a window interface of the target application.

Here, the first display output mode may be any suitable mode, for example, a split screen mode, a picture-in-picture mode, an overlay mode, a splicing mode, etc. The second display output mode may be any suitable mode, for example, a split screen mode, a picture-in-picture mode, an overlay mode, a splicing mode, etc. In some embodiments, the first display output mode and the second display output mode are different modes.

In some embodiments, the second display output mode may be determined by the compensation parameter. The method for determining the second display output mode may include but is not limited to: a database, a mapping relationship, etc. The mapping relationship is a mapping relationship between the compensation parameter and the second display output mode.

In some embodiments, by switching the display screen from the current first display output mode to the second display output mode, the display layout of the display screen can be changed to adjust the first image parameter of the imaged image. For example, by switching the overlay mode to the picture-in-picture mode, a window with poor presentation effect can be displayed and output in a picture-in-picture manner, thereby improving the presentation effect of the display output content.

In some embodiments, the adjustment order of the display output of the display screen can be determined based on the priority of the display output of the display screen. The priority of the display output of the display screen includes the priority of the display parameters, the priority of the display output content, the priority of the display output area, the priority of the display output mode, etc. The priority of the display parameters of the display screen can be any suitable level, for example, the first priority, the second priority, the third priority, the fourth priority, etc. The priority of the display output content can be any suitable level, for example, the second priority, the third priority, the fourth priority, etc. The priority of the display output area can be any suitable level, for example, the second priority, the third priority, the fourth priority, etc. The priority of the display output mode can be any suitable level, for example, the second priority, the third priority, the fourth priority, etc. For example, when the priority of the display parameters of the display screen is the first priority, the priority of the display output content is the second priority, the priority of the display output area is the third priority, and the priority of the display output mode is the fourth priority, the display parameters of the display screen can be adjusted first, and if the display parameters of the display screen cannot meet the requirements, the display output content can be adjusted.

In an embodiment of the present application, by dividing the first display area into a second display area and a third display area, adjusting the display parameters of the first display area and the display parameters of the third display area, switching the first display output content to the second display output content, switching from the first display output mode to the second display output mode, etc., the scenarios for adjusting the display output of the display screen are enriched and the presentation effect of the imaging image is ensured.

Face recognition and tracking can identify and track the position changes of the face, thereby obtaining position change information.

In some implementations, when a change in the position between the target object and the display screen is detected, the position change information may be dynamically updated.

Step S104: obtaining environmental change information of the spatial environment in which the display screen is located, and updating compensation parameters for the target object based on the environmental change information.

The preset relationship may be stored in a database. Through the first preset relationship, the control parameter and the light-emitting parameter corresponding to the second position relationship may be determined. In some embodiments, the first preset relationship may be updated after the control parameter and the light-emitting parameter are determined. In some embodiments, the first preset relationship may be represented by a curve or a matrix.

In some embodiments, in different framing scenes, the control parameters and the light-emitting parameters corresponding to the second position relationship may be the same or different. A second preset relationship between the framing scene, the second position relationship, the control parameters, and the light-emitting parameters may be established. Through the second preset relationship, the control parameters and the light-emitting parameters corresponding to the second position relationship in different scenes may be determined. In some embodiments, the second preset relationship may be represented by a curve or a matrix.

In some embodiments, if the framing scene can be detected, the second preset relationship is used to determine the control parameters and lighting parameters corresponding to the second position relationship in different scenes. If the framing scene cannot be detected, the first preset relationship is used to determine the control parameters and lighting parameters corresponding to the second position relationship.

In implementation, a second threshold of the first image parameter may be determined according to the configuration information of the target light-emitting component to determine the compensation parameter according to a second difference between the second threshold and the first image parameter.

In some embodiments, a compensation parameter can be determined based on the first image parameter. When the configuration information of the display screen and the configuration information of the target light-emitting component can satisfy the compensation parameters, the display output content and/or the display output mode of the display screen is adjusted. When the configuration information of the display screen and the configuration information of the target light-emitting component cannot satisfy the compensation parameters, the display output content and/or the display output mode of the display screen is adjusted while also controlling the light-emitting parameters of the target light-emitting component.

The first light emitting parameter may be any suitable parameter, such as brightness, hue, etc.

In some embodiments, the value of the first display parameter may be between the first image parameter and the second image parameter. After the display parameter of the display screen is adjusted to the first display parameter based on the first image parameter, since the first display parameter has not reached the second image parameter, it is necessary to control the target light-emitting component to adjust to the first light-emitting parameter until the first display parameter reaches the second image parameter.

The process of adjusting the display parameters of the display screen to the first display parameters based on the first image parameters may refer to the specific implementation of the aforementioned step S102.

Under the premise that the difference information satisfies no preset condition, the display output of the display screen continues to be adjusted until the difference information satisfies the preset condition. The preset condition may be any suitable condition, for example, not greater than a target difference value, less than a target difference value, or similar to a target difference value.

The usage or application scenarios may include but are not limited to: conference scenarios, entertainment and audio-visual scenarios, social scenarios, etc.

In some embodiments, the corresponding use or application scenario can be determined based on the purpose of the imaged image, and the compensation parameter can be determined according to the difference information between the standard image parameter and the first image parameter in the use or application scenario, so as to adjust the first image parameter by the compensation parameter, and then the difference information between the adjusted standard image parameter and the first image parameter is determined, and the adjustment of the display output of the display screen is completed on the premise that the difference information meets the preset condition. On the premise that the difference information meets the preset condition, the display output of the display screen continues to be adjusted until the difference information meets the preset condition. The preset condition can be any suitable condition, for example, not greater than the target difference value, less than the target difference value, close to the target difference value, etc.

In some embodiments, the target image parameter can be determined based on the first positional relationship, and then the compensation parameter can be determined based on the difference information between the target image parameter and the first image parameter, so as to adjust the first image parameter by the compensation parameter, and then the difference information between the adjusted first image parameter and the target image parameter is determined, and the adjustment of the display output of the display screen is completed on the premise that the difference information satisfies the preset condition. On the premise that the difference information satisfies the preset condition, the display output of the display screen continues to be adjusted until the difference information satisfies the preset condition. The preset condition can be any suitable condition, for example, not greater than the target difference value, less than the target difference value, similar to the target difference value, etc.

In the implementation manner of the present application, the display output of the display screen is adjusted by using user portrait information, environmental parameters of the spatial environment, the purpose of the imaged image, and the first position relationship, thereby broadening the scenarios for adjusting the display output of the display screen and improving the accuracy of adjusting the display output of the display screen.

Step S202: controlling the display output of the display screen based on the first image parameters to compensate for the imaging parameters of the target object using the display output of the display screen, so that the target object has second image parameters in the imaged image; wherein the presentation effect of the target object under the second image parameters is better than the presentation effect under the first image parameters.

Here, the display output of the display screen may include but is not limited to: at least one of the light emitting parameters of the light emitting component, the display parameters of the display screen, the display output area, the display output content, and the display output mode. The imaging parameters of the target object may be any suitable parameters, such as brightness parameters, color parameters, detail parameters, etc.

In some embodiments, compensating for the imaging parameters of the target object may be compensating for parameters such as brightness, color temperature, hue, and refresh rate of the display screen, or may be compensating for parameters such as brightness and color temperature of the target light-emitting element. In implementation, the parameters of the display screen may be compensated first to obtain the first display parameters, and when the first display parameters do not reach the second image parameters, the parameters of the target light-emitting element may be compensated. In some embodiments, the first display parameter may be the same as the first image parameter and the second image parameter.

In the embodiment of the present application, the imaging parameters of the target object are compensated through the display output of the display screen, thereby improving the presentation effect of the imaging image and the success rate of the display control method, thereby improving the user experience.

In the related art, a display device can be used to frame a target object (e.g., a person) to generate an image. However, in the case of a poor framing environment (e.g., dim light), the image generated by the display device has a poor display effect (e.g., the face is dark and blurry). Some solutions use algorithms to increase the brightness of the face, but the frame rate of the image is low and may produce a jello effect. At the same time, the use of algorithms will increase the noise of the image, requiring noise reduction processing, increasing the workload of the GPU, and there are problems such as a large number of computing resources and low processing efficiency.

The embodiment of the present application provides a display control method, which controls the display output of a display screen by obtaining the first image parameter of a target object in an imaged image, so as to adjust the image parameter of the target object in the imaged image from the first image parameter to the second image parameter. On the one hand, since the presentation effect of the target object under the second image parameter is better than the presentation effect under the first image parameter, the display effect of the imaged image is optimized and the user experience is improved; on the other hand, by adjusting the image parameters of the imaged image by controlling the display output of the display screen, compared with processing the imaged image through an algorithm, the noise on the imaged image is reduced while also saving the computing resources of the GPU, thereby improving the processing efficiency of the imaged image.

FIG5 is a flow chart of a display control method according to an embodiment of the present application. As shown in FIG5 , the method includes steps S301 to S310, wherein:

Step S301, after the video conferencing software is turned on, the processor uses a camera to frame the target object to obtain an imaging image;

Step S302, using the ISP unit, APU and NPU of the DSP chip to obtain the face brightness of the target object in the image and the ambient brightness of the conference scene;

Step S303, the DSP chip determines whether the face brightness and the ambient brightness meet the preset conditions, if not, it goes to step S304, otherwise, it goes to step S310;

Step S304, the DSP chip sends the fill light operation signal, the face brightness and the environment brightness to the processor;

Step S305, the processor determines a compensation parameter based on the face brightness and the ambient brightness in response to the fill light operation signal;

Step S306: the processor adjusts the display screen from including only the first display area to including the second display area and the third display area based on the compensation parameter, wherein the third display area is arranged outside the second display area, and the third display area displays monochromatic light;

Step S308: the processor adjusts the screen brightness and color temperature of the third display area of the display screen in response to the user operation to perform a fill light operation;

Step S309, the processor updates the compensation parameters for the target object;

Step S310, end.
