[0026] In some embodiments, the display 260 includes a display function component for presenting a picture, and a driving component for driving an image display. The display 260 is used to receive an image signal output from the controller 250 for display. For example, the display 260 can be used to display video content, image content, and components of a menu control interface and a user control UI interface.

[0027] In some embodiments, the communication device 220 is a component for communicating with an external device or server 400 according to various communication protocol types. The display device 200 may be provided with a plurality of communication devices 220 according to different supported communication modes. For example, when the display device 200 supports wireless network communication, the display device 200 may be provided with a communication device 220 including a WiFi function. When the display device 200 supports Bluetooth connection communication, the display device 200 needs to be provided with a communication device 220 including a Bluetooth function.

[0028] The communication device 220 can enable the display device 200 to communicate with the external device or server 400 by wireless or wired connection. Among them, the wired connection can connect the display device 200 with the external device through components such as data cables and interfaces. The wireless connection can connect the display device 200 with the external device through wireless signals or wireless networks. The display device 200 can establish a connection relationship with the external device directly, or indirectly establish a connection relationship through a gateway, a router, a connection device, etc.

[0029] In some embodiments, the controller 250 may include at least one of a central processing unit, a video processor, an audio processor, a graphics processor, and a power processor, and a first interface to an nth interface for input / output. The controller 250 controls the operation of the display device and responds to the user's operation through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200.

[0030] In some embodiments, the controller 250 and the tuner-demodulator 210 may be located in different separate devices, that is, the tuner-demodulator 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0031] In some embodiments, the user may input a user command through a graphical user interface (GUI) displayed on the display 260 , and the user input interface receives the user input command through the graphical user interface (GUI).

[0032] In some embodiments, the audio output device 270 may be a local speaker of the display device 200, or may be an external audio output device of the display device 200. In particular, for the external audio output device of the display device 200, the display device 200 may also be provided with an external audio output terminal, and the audio output device may be connected to the display device 200 through the external audio output terminal to output the sound of the display device 200.

[0033] In some embodiments, the user input interface 280 may be used to receive instructions from a user.

[0034] In order to perform user interaction, in some embodiments, the display device 200 may run an operating system. The operating system is a computer program for managing and controlling hardware resources and software resources in the display device 200. The operating system can control the display device to provide a user interface, for example, the operating system can directly control the display device to provide a user interface, or can provide a user interface by running an application program. The operating system also allows the user to interact with the display device 200.

[0035] It should be noted that the operating system may be a native operating system based on a specific operating platform, or a third-party operating system deeply customized based on a specific operating platform, or an independent operating system specially developed for the display device.

[0036] The operating system can be divided into different modules or layers according to the functions implemented, such as Figure 3 As shown, in some embodiments, the system is divided into four layers, from top to bottom, namely, the application layer (Applications layer) (referred to as "application layer"), the application framework layer (Application Framework layer) (referred to as "framework layer"), the system library layer and the kernel layer.

[0037] In some embodiments, the application layer is used to provide services and interfaces for applications so that the display device 200 can run applications and interact with users based on applications. At least one application can be run in the application layer, and these applications can be window programs, system settings programs, clock programs, etc. that come with the operating system; they can also be applications developed by third-party developers. In specific implementations, the application packages in the application layer are not limited to the above examples.

[0038] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications. The application framework layer includes some predefined functions. The application framework layer is equivalent to a processing center that determines the actions of applications in the application layer. Applications can access system resources and obtain system services during execution through the API interface.

[0039] like Figure 3 As shown, in the embodiment of the present application, the application framework layer includes a view system, managers, content providers, etc., wherein the view system can design and implement the interface and interaction of the application, and the view system includes lists, grids, text boxes, buttons, etc. The manager includes at least one of the following modules: an activity manager is used to interact with all activities running in the system; a location manager is used to provide system services or applications with access to system location services; a package manager is used to retrieve various information related to the application package currently installed on the device; a notification manager is used to control the display and clearing of notification messages; and a window manager is used to manage icons, windows, toolbars, wallpapers, and desktop components on the user interface.

[0040] In some embodiments, the activity manager is used to manage the life cycle of each application and the usual navigation back function, such as controlling the exit, opening, and back of the application. The window manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, capturing the screen, and controlling the display window changes, for example, reducing the display window, shaking the display, distorting the display, etc.

[0041] In some embodiments, the system runtime layer can provide support for the framework layer. When the framework layer is used, the operating system will run the instruction library contained in the system runtime layer, such as the C / C++ instruction library, to implement the functions to be implemented by the framework layer.

[0042] In some embodiments, the kernel layer is a functional layer between the hardware and software of the display device 200. The kernel layer can implement functions such as hardware abstraction, multitasking, and memory management. Figure 3As shown, the kernel layer may be configured with hardware drivers, and the drivers included in the kernel layer may be at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0043] It should be noted that the above example is only a simple division of the operating system functions and does not constitute a limitation on the specific operating system form of the display device 200 in the embodiment of the present application. Depending on factors such as the function of the display device and the type of operating system, the number of levels and specific level types contained in the operating system may be expressed in other forms.

[0044] Based on the above display device 200, a specific screen can be presented. For example, a playback screen, a control interface, and other application program interfaces. Figure 4 As shown, the display device 200 can render and display the picture in real time through an image generation (Image Producer) module, an image rendering (surface flinger) module, a synthesis (Composer) module, a video process (Video Processing Unit hardware, VPU hardware) module and a display (screen).

[0045] In the process of displaying the picture, the graphics interface (openGLES) of the image generation module can be connected to the application on the display device 200 to generate image content and pass the image content to the image rendering module. The image rendering module is used to control the display 260 to display content, that is, to render the image content through the user interaction layer (UI layer) or the video layer (video layer) according to the image content. In order to obtain a better display effect, the image content of the UI layer can be rendered by the GPU component, so as to form a picture frame for display in the synthesis module. Among them, the synthesis module can form the picture content by software or hardware. For example, the synthesis module can be a hardware synthesis (Hardware Composer, HWC) module.

[0046] In the synthesis module, the picture frames can be stored through the frame buffer and the video buffer, and the picture content can be formed in the corresponding layers through the video process module. That is, the image frames generated by the video playback process form the picture content through the video plane, and the image frames of other graphic pictures (such as touch tracks, graphics, etc.) form the picture content through the graphic layer (Overlay Screen Display, OSD layer). Finally, the display device 200 forms the final picture through the blending unit (blend) of the video process module and displays it on the display 260.

[0047] In the above embodiment, when displaying the user interface, the display device 200 may perform overlay display through multiple layers, and different layers have different screen display modes.

[0048] In some embodiments, the display device 200 can display images through the Video layer and the OSD layer. Among them, the Video layer can establish a connection relationship with the media player of the image generation module to display the image content generated by the media player by playing the media data. For example, when the display device 200 plays video media, the media player can parse the media data to form multiple frames of media images, and send the multiple frames of media images to the Video layer respectively to form a video playback image. The Video layer can display images based on the content, format, type, decoding specifications, image quality parameters, etc. of the media data, so as to obtain a better image display effect.

[0049] It should be noted that the Video layer is not only used to display video-type media content, but also can be used to display other types of media content. For example, the Video layer can also display a picture detail interface, that is, picture-type media data can be displayed in the Video layer.

[0050] In some embodiments, the display device 200 can also perform image quality processing on the image content through the Video layer when the video layer displays the image content, such as contrast adjustment, brightness adjustment, color correction, etc., so as to improve the image quality displayed by the video layer. For example, a plurality of image quality mode options can be preset in the operating system of the display device 200, including standard, soft, vivid, eye protection, etc. The user can select one of the image quality modes according to viewing needs, and the display device 200 can perform image quality processing on the displayed image content according to the selected image quality mode. For example, when the user selects the vivid mode, the display device 200 will enhance the color saturation and brightness in the image content through the video layer, making the image content more vivid and bright, and then display the image frame with adjusted image quality through the video layer.

[0051] The OSD layer can refresh and display some image-related information in real time according to the interactive operation process of the display device 200. For example, graphics, text, icons, etc. Of course, the OSD layer is not only used to display media content of the picture type, but also can be used to display other types of media content. For example, the OSD layer can also display video-type media content, that is, the media screen obtained by parsing the video media can be displayed in the OSD layer.

[0052] It is understandable that the Video layer can adjust the image quality of the media data to achieve image quality processing of the display screen, while the OSD layer does not have the image quality processing function of the Video layer and cannot directly perform image quality adjustment on the media data.

[0053] In order to improve the smoothness and high-quality display, the screen display process of the display device 200 is completed through the cooperation of the Video layer and the OSD layer. The Video layer can be used to display video-type media content, and the OSD layer can be used to display various UI elements and information. For example, the Video layer displays video data, and the OSD layer displays various controls for controlling video data, such as a pause button, a playback progress bar, and a volume control. The display level of the OSD layer can be higher than that of the Video layer, so that the graphics and other content displayed on the OSD layer can appear on the video playback screen, so that users can perform interactive operations based on the content displayed on the OSD layer.

[0054] In some embodiments, in order to improve the user experience, the display device 200 can adjust parameters such as color saturation, contrast, and brightness so that the displayed image content can present different filter effects. For example, a color enhancement filter, a black and white filter, a retro filter, a soft filter, etc. can be set according to the user's preferences. For another example, for color-deficient users with color blindness or color weakness, red / green filters, green / red filters, blue / yellow filters, and grayscale modes can be set. For example, for users with red color blindness or red color weakness, such users have lost or weak red color discrimination and are less sensitive to the red end of the spectrum, thus viewing red as a dark color. Therefore, a red / green filter can be set; for users with green color blindness or green color weakness, such users have lost or weak green color discrimination and view green as dark black or gray. Therefore, a green / red filter can be set; for users with tritanopia or tritanopia, such users confuse blue and yellow but can distinguish red and green. Therefore, a blue / yellow filter can be set; for users with total color blindness, such users cannot distinguish colors at all and only have a distinction between black, gray, and white. They feel that red and green are dark, and yellow and blue are bright. Therefore, a grayscale mode can be set.

[0055] Based on the above display system structure, the screen content presented by the display device 200 is presented based on the Video layer and the OSD layer. In order to improve the screen display effect, the display device 200 can set the filter effect of the Video layer and the OSD layer at the same time, so that the Video layer and the OSD layer finally present a unified screen display effect.

[0056] In some embodiments, Figure 5 As shown, it is an architectural diagram of the filter mode setting provided in an embodiment of the present application. The application layer of the display device 200 includes a setting application, and a filter setting menu for controlling the filter effect setting is encapsulated in the setting application, which is used to interact with the user to adjust the display of different filter effects. The filter setting menu includes filter options of multiple filter modes. The display device 200 can control the display 260 to display the filter setting menu in response to a display instruction for displaying the filter setting menu. And when the display 260 displays the filter setting menu, it can generate a setting instruction for the target filter mode corresponding to the target filter option in response to the selection instruction of the target filter option. In response to the setting instruction, the video layer and the OSD layer can be set with corresponding display parameters according to the target filter mode, so that the video layer and the OSD layer present a unified filter effect.

[0057] For example, the user can open the setting menu for comfortable vision provided by the display device 200 through the control device 100, so that the display 260 presents the following Figure 6 The menu interface shown includes multiple visual setting items such as light sensitivity brightness, light sensitivity color temperature, eye protection mode, color vision optimization, etc.

[0058] When the display 260 displays the setting menu, the user clicks the "color optimization" option in the setting menu through the control device 100, so that the display device 200 controls the display 260 to present the color optimization menu. Figure 7 The menu interface is shown. The color vision optimization menu includes filter options such as no filter, red / green filter, green / red filter, blue / yellow filter, grayscale mode, etc. Users can choose the corresponding filter effect mode based on their own needs.

[0059] When the user clicks on the "Red / Green Filter" option in the color optimization menu through the control device 100, the display device 200 can detect the confirmation key value input by the control device 100, and generate a setting instruction for the red / green filter mode according to the filter option position where the current focus is located. In response to the setting instruction, the Video layer and the OSD layer can be set at the same time so that the Video layer and the OSD layer present the filter effect of the red / green filter mode.

[0060] In some embodiments, different display device 200 models support different functions, so the display device 200 can detect whether the display device 200 supports the filter adjustment function. If the display device 200 supports the filter adjustment function, the filter setting operation for the Video layer and the OSD layer can be performed. If the display device 200 does not support the filter adjustment function, the filter setting operation for the Video layer and the OSD layer is not performed.

[0061] In some embodiments, whether the display device 200 supports the filter adjustment function can be determined based on the whole device attribute list of the display device 200. The whole device attribute list includes a series of inherent characteristics and functions of the display device 200, including but not limited to attribute information such as hardware configuration, software version, and technical specifications. Figure 8 As shown, the display device 200 can obtain the whole device attribute list (S801), read the filter attribute value in the whole device attribute list (S802), and the filter attribute value is used to indicate whether the display device 200 supports the filter adjustment function. If the filter attribute value is the first attribute value, it means that the display device 200 supports the filter adjustment function, and the display 260 can be controlled to display the filter setting menu (S803). If the filter attribute value is the second attribute value, it means that the display device 200 does not support the filter adjustment function, and the display 260 is controlled not to display the filter setting menu (S804).

[0062] For example, the first attribute value may be 1, indicating that the display device 200 supports the filter adjustment function, and the second attribute value may be 0, indicating that the display device 200 does not support the filter adjustment function.

[0063] In some embodiments, the display device 200 supports a power-on / off memory function for the filter mode. When the display device 200 is turned off, the display device 200 will record the current filter mode settings. When the display device 200 is turned on again, the display device 200 will automatically load and apply the corresponding filter mode according to the previously recorded filter mode settings. That is, in response to a shutdown command, the display device 200 can record the current filter mode. In response to a power-on command, the display device 200 can obtain the filter mode recorded at the last shutdown, and automatically set the corresponding filter parameters for the Video layer and the OSD layer according to the recorded filter mode, so that the screen display effect presented before and after the power on and off is consistent.

[0064] In some embodiments, the display device 200 may also change the current display mode of the display device 200 from the filter mode to the non-filter mode in response to the setting instruction indicating the factory settings are restored. That is, when the display device 200 is restored to the factory settings, the display mode is adjusted to the factory default mode, that is, the non-filter mode, and the display device 200 presents the original image color without filter processing.

[0065] In some embodiments, for the filter effect settings of the Video layer and the OSD layer, the display device 200 may pre-configure the image quality parameters and color matrices corresponding to different filter modes. When setting the filter mode, the image quality parameters and color matrix associated with the filter mode may be directly obtained, and the image quality parameters may be configured to the Video layer, and the color matrix may be configured to the OSD layer. By configuring the image quality parameters and color matrix associated with the filter mode for both the Video layer and the OSD layer at the same time, the Video layer and the OSD layer may finally present a unified filter effect.

[0066] The image quality parameters are display gain parameters in the Video layer that determine the image display effect, including parameters related to the image display such as color space, color depth, contrast, brightness, and saturation. The color matrix is ​​a transformation matrix that performs pixel value transformation on the image. The pixels of the image can be linearly transformed by matrix operations. For example, the color matrix can be ColorMatrix, which is a 4x5 floating-point value matrix. By performing matrix multiplication operations on ColorMatrix and the color value matrix of the image pixels, a new color value matrix is ​​obtained, thereby changing the image display effect.

[0067] In some embodiments, Fig. 9 As shown, the display device 200 can define the filter type parameters of the filter mode (S901), and set the image quality parameters and color matrix of the filter mode (S902). Among them, the filter type parameters are used to characterize the type of the filter mode. Then establish the association relationship between the image quality parameters and the filter type parameters (S903), and establish the association relationship between the color matrix and the filter type parameters (S904). Then store the image quality parameters and the color matrix (S905). When setting the target filter mode, the target filter type parameters of the target filter mode can be obtained, and the target image quality parameters and target color matrix associated with the target filter mode can be queried according to the target filter type parameters.

[0068] For example, Figure 7 Taking the filter setting menu shown in the figure as an example, the filter setting menu includes five filter modes: no filter, red / green filter, green / red filter, blue / yellow filter and grayscale mode. A value of 0-4 can be used as the filter type parameter, which represents five filter modes: no filter, red / green filter, green / red filter, blue / yellow filter and grayscale mode. And based on the above filter type parameters, the corresponding image quality parameters and color matrix are associated with each filter mode.

[0069] In some embodiments, when the display device 200 sets the image quality parameters and color matrix of the filter mode, it can obtain a basic sample image and a target sample image, and set the image quality parameters and color matrix of the filter mode according to the basic sample image and the target sample image, wherein the basic sample image is an image without a filter effect, and the target sample image is an image with a target filter effect.

[0070] For the color matrix, the display device 200 can obtain the color value matrix of the pixels in the target sample image and the color value matrix of the pixels in the basic sample image, calculate the ratio between the color value matrix of the pixels in the target sample image and the color value matrix of the pixels in the basic sample image, and use the ratio as the color matrix.

[0071] For the image quality parameters, the display device 200 can obtain the display parameters of the target sample image and the display parameters of the basic sample image, calculate the difference between the display parameters of the target sample image and the display parameters of the basic sample image, and use the difference as the image quality parameter. That is, the image quality parameter includes an offset parameter value, and the offset parameter value is the parameter value of the display parameter increased or decreased to achieve the target filter effect. For the image quality parameter, when the Video layer is subsequently configured, the current image quality parameter of the Video layer can be modified based on the offset in the image quality parameter.

[0072] The display device 200 can also obtain the display parameters of the target sample image and use the display parameters of the target sample image as the image quality parameters. That is, the image quality parameters include specific display parameters, that is, display parameters corresponding to the target filter effect. For the image quality parameters, when the Video layer is subsequently configured, the current image quality parameters of the Video layer can be directly changed to the image quality parameters.

[0073] It can be understood that by setting the image quality parameters and color matrix based on sample images with and without filter effects, and configuring them to the Video layer and the OSD layer respectively, the uniformity of the filter effects finally presented by the Video layer and the OSD layer can be improved.

[0074] In some embodiments, Fig.10 As shown, for the filter effect setting of the Video layer and the OSD layer, the display device 200 can receive a setting instruction of a target filter mode (S1001), wherein the target filter mode is associated with a preset target image quality parameter, and the target filter mode is associated with a preset target color matrix.

[0075] In response to the setting instruction, the first filter setting interface (S1002) is called, and the target image quality parameters are configured to the Video layer (S1003) through the first filter setting interface, so that the Video layer displays the picture based on the target image quality parameters. At the same time, the second filter setting interface (S1004) is called, and the target color matrix is ​​configured to the OSD layer (S1005) through the second filter setting interface, so that the OSD layer displays the picture according to the target color matrix. By configuring the image quality parameters and color matrix associated with the filter mode for the Video layer and the OSD layer at the same time, the Video layer and the OSD layer finally present a unified filter effect.

[0076] The first filter setting interface is an interface preset in the Video layer for configuring image quality parameters. The second filter setting interface is a system-level interface in the display device 200 for configuring the filter effect function of the OSD layer.

[0077] In some embodiments, Fig.11 As shown, for the Video layer filter effect setting, the display device 200 can obtain the target filter type parameters of the target filter mode (S1101), and query the target image quality parameters associated with the target filter type parameters (S1102), transmit the image quality parameters to the Video layer through the first filter setting interface, and enable the Video layer to adjust its internal processing mechanism based on the image quality parameters, so that the Video layer displays the picture based on the target image quality parameters during the subsequent playback process and presents the target filter effect.

[0078] In some embodiments, the image quality parameter is a specific display parameter value associated with the filter mode, that is, the display device 200 can call the first filter setting interface to change the current image quality parameter of the Video layer to the target image quality parameter (S1103) through the first filter setting interface, so that the Video layer displays the picture according to the target image quality parameter.

[0079] That is to say, for the filter effect setting of the Video layer, the current image quality parameters of the Video layer can be directly replaced with specific display parameter values ​​in the image quality parameters associated with the filter mode, so that the Video layer displays the picture according to the image quality parameter values ​​associated with the filter mode.

[0080] In some embodiments, the image quality parameter is an offset parameter value associated with the filter mode, that is, the display device 200 can call the first filter setting interface, read the current image quality parameter of the Video layer through the first filter setting interface, and modify the current image quality parameter of the Video layer based on the offset in the target image quality parameter (S1104), so that the Video layer displays the picture according to the modified image quality parameter.

[0081] That is to say, for the filter effect setting of the Video layer, you can adjust it based on the current image quality parameters of the Video layer based on the offset parameter value associated with the filter mode, that is, perform addition and subtraction operations on the current image quality parameters, thereby modifying the current image quality parameters so that the Video layer displays the picture according to the modified image quality parameters.

[0082] It can be understood that, for the above two configuration methods, the method of directly adjusting the current image quality parameters of the Video layer to specific parameter values ​​will directly replace the current image quality parameters of the Video layer with new, specific parameter values. That is, all previous image quality parameter settings of the Video layer will be overwritten by the new parameter values, so that the display device 200 only presents one filter effect. And the method of adjusting the parameter value based on the current image quality parameters of the Video layer will retain the current image quality parameter settings of the Video layer, and superimpose the new image quality parameter adjustment on the current image quality parameters, so that the display device 200 can present the superposition effect of multiple filters.

[0083] For example, if the current Video layer has configured the image quality parameters of the eye protection mode, on this basis, when setting the red / green filter mode, the image quality parameter adjustment of the red / green filter mode will be superimposed on the image quality parameters of the eye protection mode, so that the effect of the red / green filter is superimposed on the effect of the eye protection mode.

[0084] Below Figure 7 Taking the five filter modes shown in the figure as an example, the filter effect settings of the Video layer are explained.

[0085] To achieve Figure 7 For the five filter modes shown, the display device 200 can set a first filter setting interface in the Video layer, and define a process named hsTVSetColorVisionOptimization in the first filter setting interface to set the filter effect. The process includes an identifier (key): s32OptMode, and the s32OptMode parameter is used to specify the type of filter effect. It also includes parameter values ​​(value) associated with the key that characterize different types of filter effects. The value is a value of 0-4, and the values ​​of 0-4 represent five filter modes: no filter, red / green filter, green / red filter, blue / yellow filter, and grayscale mode, corresponding to Figure 7 The interface shown has filter options for None, Red / Green Filter, Green / Red Filter, Blue / Yellow Filter, and Grayscale Mode.

[0086] This process can receive s32OptMode as an input parameter, and load and apply the image quality parameters required by the corresponding filter effect according to the value of the parameter. In the Video layer, when the hsTVSetColorVisionOptimization process is called, the s32OptMode parameter can be read, and the image quality parameters corresponding to the s32OptMode parameter can be loaded, so that the picture can be displayed according to the image quality parameters.

[0087] In order to realize the above five filter modes, the display device 200 can pre-associate a set of fixed image quality parameter settings for each filter mode. The optimization principle of the filter mode based on the red / green filter is to reduce the green, the optimization principle of the filter mode based on the green / red filter is to increase the red, the optimization principle of the filter mode based on the blue / yellow filter is to increase the blue, and the optimization principle of the grayscale mode is to set the saturation to 0. The preset image quality parameters may include the offset corresponding to the white balance parameter and the color correction parameter, and the current image quality parameters of the Video layer are adjusted by the offset.

[0088] The following table shows detailed information about the image quality parameters.

[0089]

[0090] Take setting the red / green filter as an example: User in Figure 7 In the interface shown, select the filter option corresponding to the red / green filter. The setting application will call the first filter setting interface and set the value of the s32OptMode parameter to 1. In the Video layer, the interface will load the image quality parameters corresponding to the red / green filter effect according to the received s32OptMode parameter, and adjust the current image quality parameters of the Video layer based on the image quality parameters corresponding to the red / green filter effect. By adjusting the current image quality parameters of the Video layer through the offset, the relative intensity of red and green in the image can be changed, thereby presenting the effect of the red / green filter.

[0091] As shown in the following table, the white balance parameters and color correction parameters corresponding to different filter effects correspond to the offset. Among them, " / " means no adjustment is required, "+" means increase, and "-" means decrease. For example, for the red / green filter, you can increase R in the current white balance parameter by A1, reduce G by B1, and increase B by C1. In the current color correction parameter, increase the saturation of red by E1, reduce the hue of yellow by G1, increase the saturation of purple by H1, and increase the hue of skin color by I1.

[0092]

[0093] In some embodiments, for the OSD layer filter effect setting, the display of the OSD layer is realized by calling the native interface of the operating system of the display device 200. Therefore, the display device 200 can enable and configure the filter effect function based on the native interface (settings.secure) in the operating system, that is, the filter setting item identifier (accessibility_display_daltonizer_enabled) and the filter type item identifier (accessibility_display_daltonizer) in the operating system can be set through the settings.secure interface. The two identifiers (Key) of accessibility_display_daltonizer_enabled and accessibility_display_daltonizer are used to control the enabling and type of the filter effect function of the display device 200.

[0094] The filter setting item identifier is used to control the running state of the filter effect function, indicating whether the filter effect function of the OSD layer is turned on. When the filter setting item identifier is set to the first parameter, it indicates that the filter effect function of the OSD layer is turned on, and when the filter setting item identifier is set to the second parameter, it indicates that the filter effect function of the OSD layer is turned off.

[0095] Therefore, the display device 200 detects the current display mode, and the display mode is a filter mode or a non-filter mode. If the current display mode is not a non-filter mode, the second filter setting interface, i.e., the settings.secure interface, is called, and the filter setting item identifier is set to the first parameter through the second filter setting interface to enable the filter effect function of the OSD layer. If the current display mode is a non-filter mode, the filter setting item identifier is set to the second parameter through the second filter setting interface to disable the filter effect function of the OSD layer.

[0096] For example, Figure 7 The five filter modes shown in the figure are as follows: no filter, red / green filter, green / red filter, blue / yellow filter and grayscale mode. When setting the no filter mode, the filter setting item flag can be set to 0, indicating that the filter effect function of the OSD layer is turned off. When setting the other four filter modes, the filter setting item flag can be set to 1, indicating that the filter effect function of the OSD layer is turned on.

[0097] The filter type item identifier is used to set the type of filter mode, which characterizes the type of filter mode of the OSD layer. The filter type item identifier can use different parameter values ​​to represent different filter modes. In some embodiments, the filter type item identifier can be synchronized with the filter type parameters that characterize the filter mode defined by the display device 200. That is, the display device 200 can obtain the target filter type parameters of the target filter mode, and set the filter type item identifier as the target filter type parameters through the second filter setting interface.

[0098] For example, Figure 7 The five filter modes shown in the figure are no filter, red / green filter, green / red filter, blue / yellow filter and grayscale mode as examples. Use values ​​0-4 as filter type parameters, which represent five filter modes: no filter, red / green filter, green / red filter, blue / yellow filter and grayscale mode. Correspondingly, the filter type item identifier can be set to values ​​1-4 to represent different filter modes, which respectively represent that when the filter effect function of the OSD layer is turned on, the filter mode of the OSD layer is red / green filter, green / red filter, blue / yellow filter.

[0099] Based on the above second filter setting interface, when setting the target filter mode, such as Fig.11 As shown, the display device 200 can obtain the filter type item identification as the target filter type parameter (S1101), can query the target color matrix associated with the target filter type parameter (S1105), and correspond to the Framework layer of the display device 200, and change the current color matrix set in the Framework layer to the target color matrix (S1106) to configure the target color matrix to the OSD layer. When it is necessary to display the picture, the original color value matrix of the pixels in the picture to be displayed can be obtained, the target color value matrix is ​​calculated based on the target color matrix set in the Framework layer, and the picture to be displayed is displayed in the OSD layer according to the target color value matrix. Among them, the target color value matrix is ​​obtained by performing a matrix multiplication operation on the target color matrix and the original color value matrix.

[0100] That is to say, by calling the settings.secure interface to modify the system settings of the Framework layer in the operating system, the color matrix configured in the Framework layer is changed, so that the Framework layer can apply the target color matrix associated with the target filter mode to the graphics rendering process, so as to process the image to be displayed through the target color matrix, and display the processed image data through the OSD layer, thereby presenting the target filter effect.

[0101] Below Figure 7 Taking the five filter modes shown in the figure as an example, the filter effect settings of the OSD layer are explained.

[0102] To achieve Figure 7 For the five filter modes shown, the display device 200 can enable and configure the filter effect function through the settings.secure interface. In the Android system, the two identifiers (keys) accessibility_display_daltonizer_enabled and accessibility_display_daltonizer are used to control the enabling and type of the filter effect function.

[0103] Among them, when accessibility_display_daltonizer_enabled is 0, it means turning off the filter effect. When accessibility_display_daltonizer_enabled is 1, it means turning on the filter effect. accessibility_display_daltonizer includes values ​​1-4, which represent four filter modes: red / green filter, green / red filter, blue / yellow filter and grayscale mode. Different filter effects can be achieved by adjusting the above two parameters.

[0104] Take setting the red / green filter as an example: User in Figure 7 In the interface shown, select the filter option corresponding to the red / green filter. The settings application will call the settings.secure interface, set accessibility_display_daltonizer_enabled to 1, and set accessibility_display_daltonizer to 1. In the Framework layer, when the setting item in Settings.Secure is detected to change, the color matrix ColorMatrix corresponding to the red / green filter effect can be loaded according to the value of accessibility_display_daltonizer, and the current ColorMatrix can be modified based on ColorMatrix. The modified ColorMatrix will be applied to the image rendering process of the Framework layer, and all image data processed by the Framework layer will adjust the color value according to the ColorMatrix. Finally, the processed image data will be displayed through the OSD layer.

[0105] Images or videos are composed of dot matrix and color values. Dot matrix is ​​a matrix containing pixels. Color values ​​include RGBA values, where A is transparency, R is the red channel component, G is the green channel component, and B is the blue channel component. For ColorMatrix, ColorMatrix can change the color value of the pixel of the image based on matrix multiplication operation.

[0106] For example, the color matrix ColorMatrix is ​​a 4X5 matrix A, and the pixel value matrix of the pixel points in the image to be displayed is C. The color value of the pixel point can be changed according to the following formula:

[0107] Among them, matrix A is ColorMatrix, the first row of matrix A determines the red channel component of the new color, the second row of matrix A determines the green channel component of the new color, the third row of matrix A determines the blue channel component of the new color, the fourth row of matrix A determines the transparency of the new color, the fifth column value in matrix A is used to determine the offset in each component, matrix C is the original pixel value matrix of the image to be displayed, and matrix R is the pixel value matrix of the pixel points when the image to be displayed is finally displayed. The filter effect is adjusted by changing the color offset or the coefficient of the corresponding RGBA value.

[0108] In this embodiment, for the setting of the filter effect, the Video layer and the OSD layer are set at the same time, so that the Video layer and the OSD layer present a unified filter effect. The Video layer is to set an interface for configuring the image quality parameters in the Video layer, and to adjust the image quality parameters to achieve the corresponding filter effect. The OSD layer is to call the native interface of the operating system, modify the system settings of the Framework layer in the operating system, change the color matrix configured in the Framework layer, and achieve the corresponding filter effect based on the color matrix.

[0109] In addition, it should be understood that Fig. 9 , Fig.10 , Fig.11 The specific order in which the operations are described is only exemplary and is not intended to indicate that the order is the only order in which the operations can be performed.
