Due to the use of the camera function on the TV, when previewing the camera video, it is generally displayed on the graphics layer, while the SOC (System On a Chip, system-on-chip) chip of the TV generally does not improve the image quality of the content of the graphics layer. Therefore, when previewing the camera video, you will feel that the video picture effect is not bad. However, when the video is played back in the camera application of the TV, it needs to pass through the media player, and the video content decoded by the media player of the TV is displayed in the video layer of the SOC, so the display content of the video layer will pass through the SOC. image quality processing channel. During this process, due to the image quality processing of the SOC, the camera video is not optimized, and because the parameters such as the resolution and definition of the camera are usually different from those of the TV, the camera video is not suitable for the image quality of the general SOC. deal with. Therefore, instead, the camera video is played after the SOC is optimized, and the edge of the face will be outlined, resulting in a problem of poor display effect.

In order to solve the above problem, the present invention provides a display method, comprising: when it is detected that the display terminal enters the camera application, updating the current picture quality parameter of the display terminal to the camera mode picture quality parameter; according to the updated camera The mode picture quality parameter is used to display the to-be-played video picture of the display terminal. This method updates the current image quality parameters to the camera mode image quality parameters optimized for the camera video image quality when entering the camera application, so that when playing the camera video, the camera mode image quality parameters are used for display, while It is not displayed by the image quality parameters of the unified SOC. Solved the problem that the screen display effect was not good when playing back the camera video in the camera application, and improved the screen display effect when playing the camera video in the camera application.

An embodiment of the present invention provides a display method. Referring to FIG. 2 , FIG. 2 is a schematic flowchart of an embodiment of a display method of the present invention.

In this embodiment, the display method includes:

Step S10, when it is detected that the display terminal enters the camera application, the current image quality parameters of the display terminal are updated to the camera mode image quality parameters.

In this embodiment, the execution body is a display terminal with a camera, such as a TV with a built-in camera. Camera applications refer to applications that convert analog signals input from hardware terminals such as cameras, digital cameras, and TV cards into binary digital signals through analog-to-digital conversion programs, and play them according to the coding specifications of various digital video formats; it can be video chat Apps, home care apps, family photo apps, fitness apps and other apps usually have functions such as home care and video chat.

Detecting that the display terminal enters the camera application refers to detecting that the user opens or starts the corresponding camera application. When the corresponding camera application is opened or activated, the current image quality parameters of the display terminal are updated to the camera mode image quality parameters. Among them, the current image quality parameter refers to the image quality parameter used by the display terminal to adjust the display image before entering the camera application, which may be the image quality parameter in normal or standard mode, or the image quality parameter in other modes, such as Movie mode, game mode, photo mode, etc. The camera mode image quality parameters refer to a set of image quality parameters that are preset for display of the camera video, which can be debugged in advance and added to the middleware of the display terminal.

Optionally, referring to FIG. 3 , in step S10, the camera image quality enhancement function of the display terminal is activated, and the current image quality parameter of the display terminal is updated to the camera mode image quality parameter, which specifically includes:

Step S11, when it is detected that the display terminal enters the camera application, the preset interface state is set to the entering state.

In this embodiment, the preset interface refers to an interface for displaying the image quality mode of the camera in the terminal, and the state of the preset interface is the state of the image quality mode of the camera, which is divided into an entry state and an exit state. The state of the preset interface is used to dynamically update the image quality parameters.

When it is detected that the display terminal enters the camera application, the camera video usually needs to be played at this time, so the image quality parameters need to be updated. For this, the preset interface state needs to be set to the enter state first.

Step S12: Acquire the camera mode image quality parameter according to the entry state, and update the current image quality parameter of the display terminal to the camera mode image quality parameter.

In this embodiment, after the preset interface state is set to the enter state, the display terminal will call the corresponding interface of the middleware to notify the middleware of the state of the preset interface. Specifically, the middleware provides an external interface, so that the camera application can send the current state of the camera image quality mode to the middleware by calling this interface, that is, notify the middleware whether the current state of the camera image quality mode is the entry state or the exit state.

When the corresponding interface of the middleware is called, the middleware will dynamically update the picture quality parameters by judging the status of the camera picture quality mode. When the state of the preset interface, that is, the state of the camera image quality mode is the entry state, the middleware will update the current image quality parameters of the display terminal to the preset image quality parameters of the camera mode. Specifically, the middleware will call the driver interface by calling to update the current image quality parameters. Among them, the middleware refers to the software in the display terminal that provides the connection between the system software and the application software, so as to facilitate the communication between various parts of the software, especially the centralized business logic of the application software for the system software. Middleware is a type of software located between the platform (hardware and operating system) and the application. It has standard program interfaces and protocols. For different operating systems and hardware platforms, they can have multiple implementations that conform to the interface and protocol specifications.

Specifically, for example, by calling the corresponding interface of the preset middleware to notify the middleware of the entry status, based on the middleware, the camera mode image quality parameters are acquired, and the current image quality of the display terminal is The parameter is updated to the camera mode image quality parameter.

In this embodiment, when the camera application is detected, the state of the preset interface, that is, the state of the camera image quality mode, is set to the entry state, and the middleware interface is called, so that the middleware can obtain the current state of the camera image quality mode. To achieve dynamic refresh of image quality parameters.

Step S20: Display the video image to be played on the display terminal according to the updated image quality parameter of the camera mode.

In this embodiment, after entering the camera application, the video to be played at this time mainly refers to the camera video, wherein the camera video is mainly the video shot and recorded by the camera of the display terminal. For example, when the user is using the camera application process recorded video. That is, at this time, the display terminal will display the picture of the camera video according to the preset picture quality parameters of the camera mode, so as to realize the improvement of the picture display effect.

In this embodiment, after entering the camera application, the current picture quality parameter is automatically updated through the middleware, and the camera video picture to be played is displayed by using the updated camera mode picture quality parameter. Because the general picture quality parameters of the display terminal are not directly used for picture display, but the updated camera mode picture quality parameters optimized for the camera video are used, so the picture display effect of the camera video can be improved, and it is automatically performed. , without the need for manual operation by the user. Solved the problem that the screen display effect was not good when playing back the camera video in the camera application, and improved the screen display effect when playing the camera video in the camera application. In addition, because the image quality parameters are updated through the middleware, and the middleware can have multiple implementations conforming to the interface and protocol specifications for different operating systems and hardware, thus further achieving higher compatibility.

Further, in another embodiment of a display method of the present invention, the method further includes:

Step S30, when it is detected that the display terminal exits the camera application, restore the camera mode image quality parameter to the normal mode image quality parameter.

In this embodiment, when it is detected that the display terminal exits the camera application, it may be that the user exits or closes the camera application, or the user switches to another application (ie, a non-camera application), in order to prevent the display terminal from using other applications. Therefore, it is necessary to restore the camera mode image quality parameters to the normal mode image quality parameters.

The normal mode image quality parameter, which can also be called the standard image quality parameter, is the image quality parameter used by the display terminal when using other applications, for example, the image quality parameter used by the TV set when playing a TV program.

It should be noted that the common image quality parameters are preset in the system, which may be image quality parameters in the standard image mode preset by the system, or image quality parameters used by the user before entering the camera application.

Optionally, in step S30, when it is detected that the display terminal exits the camera application, the camera mode image quality parameter is restored to the normal mode image quality parameter, which specifically includes:

Step S31, when it is detected that the display terminal exits the camera application, the preset interface state is set to an exit state.

In this embodiment, when exiting the camera application, in order not to affect the screen display when the display terminal uses other applications, the camera image quality mode interface needs to be set to the exit state, that is, the preset interface is set to the exit state.

Step S32, according to the exit status, obtain the image quality parameter of the normal mode, and restore the image quality parameter of the camera mode to the image quality parameter of the normal mode.

In this embodiment, since the preset interface state is the exit state, it means that it is no longer necessary to use the camera mode image quality parameters for image display at this time. Therefore, the camera mode image quality parameters are restored to the normal mode image quality parameters.

Obtain the normal mode image quality parameters, that is, read the normal or standard mode image quality parameters used by the display terminal when using other applications, which can be to obtain the standard mode image quality parameters in the display terminal; or to obtain the image quality parameters before entering the camera application Display the image quality parameters used by the terminal to restore the image quality parameters when exiting the camera application.

When the display terminal exits the camera application, it will call the corresponding interface of the middleware to notify the middleware of the state of the preset interface at this time. When the corresponding interface of the middleware is called, the middleware will dynamically update the picture quality parameters by judging the status of the camera picture quality mode. When the state of the preset interface, that is, the state of the camera image quality mode, is the exit state, the middleware will call the corresponding driver interface to restore the current image quality parameters of the display terminal to the normal mode image quality parameters.

Specifically, for example, by calling the corresponding interface of the preset middleware to notify the middleware of the exit status, based on the middleware, the normal mode image quality parameters are acquired, and the camera mode image quality parameters are Return to the normal mode image quality parameters.

In this embodiment, when it is detected to exit the camera application, the state of the preset interface, that is, the state of the camera image quality mode, is set to the exit state, the image quality parameters of the normal or standard mode are obtained, and the image quality parameters are compared according to the normal or standard image quality parameters. The quality parameters are dynamically updated. It is realized that the image quality parameters are automatically restored to the image quality parameters used by other applications when leaving the camera application, or the image quality parameters when using other applications are guaranteed to be the normal mode image quality parameters, that is, it can be automatically compatible with camera application scenarios and Differences in image quality in other application scenarios. While achieving better compatibility, there is no need for the user to manually switch the image quality mode back and forth in the menu, which further achieves the technical effect of simplifying the operation.

Step S40: Display the display screen of the display terminal according to the normal mode image quality parameter.

In this embodiment, after the display terminal exits the camera application, since the camera application is no longer used at this time, the normal mode image quality parameter is used to display the display screen of the display terminal.

In this embodiment, when it is detected that the camera application exits, the image quality parameters are restored, and the normal mode image quality parameters are used to display the display screen of the display terminal, so that the display effect when using other applications is not affected. In addition, it can also ensure that when the camera application crashes due to unknown reasons, the image quality parameters can be automatically restored to the normal or standard mode image quality parameters, so as to avoid the failure to update the image quality parameters in time in this case, thereby affecting the The screen display effect when using other applications.

Further, in another embodiment of a display method of the present invention, in step S10, when it is detected that the display terminal enters the camera application, before updating the current image quality parameter of the display terminal to the image quality parameter of the camera mode, further include:

Step S60, acquiring the normal mode image quality parameter.

In this embodiment, acquiring the image quality parameters in the normal mode, that is, acquiring detailed parameters of the image quality in the normal mode, such as sharpness, contrast, saturation, and the like.

Step S70, modifying the parameter for improving the definition in the normal mode image quality parameters to a preset value.

In this embodiment, the parameter for improving the definition refers to a parameter in the picture parameters for improving the definition of the picture display for better display effect, for example, the definition parameter, the noise reduction parameter, the super-resolution function parameter Wait.

Due to the limitation of the resolution of the camera itself, the video of the camera is not suitable to be displayed directly using the image quality parameters with higher definition enhancement in the display terminal. Therefore, it is necessary to modify the parameters for improving the definition in the normal mode image quality parameters to the default values. The preset value can be customized according to the parameters of the camera of the display terminal.

For better understanding, an example is given below. For example, in a TV with a super-resolution function, in the normal mode image quality parameters, the super-resolution function parameter will be turned on, so that the SOC input is lower than 4K resolution. When the signal is received, the resolution is improved to 4K or close to 4K display effect through the algorithm. At this time, modify the parameter for improving the definition in the normal mode image quality parameters to the default value, that is, modify the parameter of the super-resolution function to off.

Specifically, for example, the definition parameter and/or the noise reduction parameter and/or the super-resolution function parameter in the normal mode image quality parameters are modified to preset values.

Step S80, determining the modified normal mode image quality parameter as the camera mode image quality parameter.

In this embodiment, the modified normal mode image quality parameter is determined as the camera mode image quality parameter, so that the camera mode image quality parameter can be stored in the display terminal.

In this embodiment, the image quality parameters in the camera mode are obtained by copying the image quality parameters in the normal image quality mode, and then modifying the image quality parameters used for improving the definition to preset values. So that it can be stored in the display terminal in advance, that is, the obtained camera mode image quality parameter is added to the middleware of the display terminal. In order to realize that when the state of the preset interface, that is, the state of the camera image quality mode is the entering state, the pre-stored camera mode image quality parameters can be directly obtained.

Further, in another embodiment of a display method of the present invention, step S10, after updating the current image quality parameter of the display terminal to the camera mode image quality parameter, further includes:

Step A10: Display a control page for camera image parameters according to the updated camera mode image quality parameters.

In this embodiment, the camera mode image quality parameter refers to a parameter for displaying a video image of the camera, that is, an image quality parameter that needs to be set separately for the resolution and definition of the camera. In specific implementation, this parameter is usually preset, and this parameter can be directly called when using.

Image parameters refer to the parameters used to adjust the image quality, including parameters such as color temperature, color, brightness, contrast, and sharpness, while the control page of the camera image quality parameters refers to allowing users to adjust or control the camera mode image quality according to their preferences. parameter page. This page is independent of the control page of the normal or standard image mode image quality parameters that the user can directly adjust or control in the menu. It is generated after the current image quality parameters are updated to the camera mode image quality parameters, that is, when the user enters the camera application. show.

For a better understanding, refer to FIG. 4 , which is a schematic diagram of a control page for the image quality parameters of the camera mode in an embodiment. In this embodiment, the display terminal is a TV with a super-resolution function. After entering the camera application, the TV will update the current image quality parameters through the middleware, and generate the camera image parameter setting page as shown in Figure 4. The "Super Resolution Function, Sharpness, Saturation, Contrast, Backlight Adjustment" on the left in Figure 4 are the types of picture quality detail parameters that users can adjust by themselves. There can be more other picture quality parameters, such as color temperature, in the specific implementation. , denoising, etc.; the right side is the control for adjusting the detailed parameters of the picture quality, the user can click the black circle control in the picture to turn on or off the super-resolution function parameters; you can also adjust the picture by sliding the black small arrow control left and right. The size of the parameter value of the quality details, the control can also have other forms during the specific implementation, which will not be described here.

It can be seen that the automatically updated image quality parameters at this time, that is, the preset camera mode image quality parameters of the TV are shown in the figure, the super-resolution function parameters are turned off, the definition is 0, the saturation is 70, and the contrast is 65. , the backlight is adjusted to 90. It should be noted that the values here are only examples. In specific implementation, the best camera mode image quality parameters can be set according to the actual situation of the display terminal. At this point, the user can further adjust the updated camera mode image quality parameters on this control page.

Step A20: Based on the user-defined operation collected on the control page, adjust the camera mode image quality parameters to form new camera mode image quality parameters.

In this embodiment, when the camera application is entered, the current image quality parameters will be updated to the preset camera mode image quality parameters, which may not meet the needs and preferences of all users. Therefore, the user can adjust the updated image quality parameters according to their own preferences through this independent control page. At this time, the image quality parameters can be adjusted according to the user's specific operation behavior, so as to obtain new camera mode image quality parameters, so that Users can customize the camera mode image quality parameters.

In this embodiment, after updating the image quality parameters of the camera mode, a control page for the image parameters of the camera is generated, so that when the user enters the camera application, after the image quality parameters are automatically updated, they can also be adjusted according to personal preferences. Image quality parameters, rather than forcing users to use the preset camera mode image quality parameters after entering the camera application, achieving a higher degree of freedom and flexibility. Moreover, since the image quality parameters are generated after updating the image quality parameters to the camera mode image quality parameters, that is, it is only displayed when the user enters the camera application, thereby avoiding affecting the parameter settings in the normal image mode.

Further, in another embodiment of a display method of the present invention, the method further includes:

If the display terminal has a camera application, the configured xml file can be downloaded uniformly . When executing the judgment, first load the xml file, read the application list in it, that is, the aforementioned application whitelist, and then dynamically compare and judge whether the opened or activated system application is the camera application in the application whitelist.

Step S02, if yes, execute the step of updating the current image quality parameter of the display terminal to the image quality parameter of the camera mode when it is detected that the display terminal enters the camera application.

In this embodiment, if it is, it means that the camera application in the preset application whitelist is entered by the display terminal. At this time, it means that the image quality parameter needs to be updated. Therefore, when it is detected that the display terminal enters the camera application, the The step of updating the current image quality parameter of the display terminal to the image quality parameter of the camera mode.

In this embodiment, by presetting the application whitelist, it is possible to update the picture quality parameters only when the user enters the corresponding camera application, thereby avoiding the impact on the picture display when using other applications. In addition, because the application whitelist can be preset in the form of an xml file, instead of having to be written in the code, and this xml file can be put together with the application or other functional configuration files, so that there is no need for one configuration file for one platform or one configuration file for one platform. Also need to modify the code separately. The technical effect of simplifying the development process and having high compatibility is achieved.
