After power-up, the kernel is started, the kernel space is activated, hardware is abstracted, hardware parameters are initialized, virtual memory, a scheduler, signal and inter-process communication (IPC) are operated and maintained. After the kernel is started, shell and user application programs are loaded again. The application program is compiled into machine code after being started to form a process.

Referring to FIG. 4, in some embodiments, the system is divided into four layers, from top to bottom, an application layer (referred to as an "application layer"), an application framework layer (Application Framework layer) (referred to as a "framework layer"), a An Zhuoyun row (Android run) and a system library layer (referred to as a "system runtime layer"), and a kernel layer, respectively.

In some embodiments, at least one application program is running in the application program layer, and these application programs may be a Window (Window) program of an operating system, a system setting program, a clock program, a camera application, and the like; and may be an application program developed by a third party developer, such as a hi-see program, a K-song program, a magic mirror program, etc. In particular implementations, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which the embodiments of the present application do not limit.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. Through the API interface, the application program can access the resources in the system and acquire the services of the system in the execution.

As shown in fig. 4, the application framework layer in the embodiment of the present application includes a manager (manager), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used to interact with all activities that are running in the system; a Location Manager (Location Manager) is used to provide system services or applications with access to system Location services; a Package Manager (Package Manager) for retrieving various information about an application Package currently installed on the device; a notification manager (Notification Manager) for controlling the display and clearing of notification messages; a Window Manager (Window Manager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.

In some embodiments, the activity manager is to: the lifecycle of each application program is managed, as well as the usual navigation rollback functions, such as controlling the exit of the application program (including switching the currently displayed user interface in the display window to the system desktop), opening, backing (including switching the currently displayed user interface in the display window to the previous user interface of the currently displayed user interface), etc.

In some embodiments, the window manager is configured to manage all window procedures, such as obtaining a display screen size, determining whether there is a status bar, locking the screen, intercepting the screen, controlling display window changes (e.g., scaling the display window down, dithering, distorting, etc.), and so on.

In some embodiments, the system runtime layer provides support for the upper layer, the framework layer, and when the framework layer is in use, the android operating system runs the C/C++ libraries contained in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the kernel layer contains at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (e.g., fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and the like.

In some embodiments, the kernel layer further includes a power driver module for power management.

In some embodiments, the software programs and/or modules corresponding to the software architecture in fig. 4 are stored in the first memory or the second memory shown in fig. 2 or fig. 3.

In some embodiments, taking a magic mirror application (photographing application) as an example, when the remote control receiving device receives an input operation of the remote control, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into the original input event (including the value of the input operation, the timestamp of the input operation, etc.). The original input event is stored at the kernel layer. The application program framework layer acquires an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and takes the input operation as a confirmation operation, wherein the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer, the magic mirror application is started, and further, a camera driver is started by calling the kernel layer, so that a still image or video is captured through a camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) acted on a display screen by a user, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (e.g., multi-window mode) and window position and size corresponding to the input operation are set by the activity manager of the application framework layer. And window management of the application framework layer draws a window according to the setting of the activity manager, then the drawn window data is sent to a display driver of the kernel layer, and the display driver displays application interfaces corresponding to the window data in different display areas of the display screen.

In some embodiments, as shown in fig. 5, the application layer contains at least one icon control that the application can display in the display, such as: a live television application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control, and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using inputs from cable television, radio broadcast, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, the video on demand application may provide video from different storage sources. Unlike live television applications, video-on-demand provides video displays from some storage sources. For example, video-on-demand may come from the server side of cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various multimedia content playing applications. For example, a media center may be a different service than live television or video on demand, and a user may access various images or audio through a media center application.

In some embodiments, an application center may be provided to store various applications. The application may be a game, an application, or some other application associated with a computer system or other device but which may be run in a smart television. The application center may obtain these applications from different sources, store them in local storage, and then be run on the display device 200.

Currently, the display device 200 generally uses an ACR (Auto Content Recognition) function to collect and display content for content recognition, and finally uses the content recognition result for enhancement of AQ (Audio Quality) and PQ (Picture Quality) of the display device 200, content recommendation, and the like, so as to enhance the experience of the user using the display device 200.

However, ACR functions also have some drawbacks, such as their content identification being dependent on third party service providers, and further such as ACR functions being supported only in specific countries, their use having limitations, etc. In order to avoid the problems caused by the aforementioned drawbacks of the ACR function, there are also some display devices 200 currently using the AIPQ (Artificial Intelligence Picture Quality, intelligent image mode switching) function. The AIPQ function is to identify a scene of the content currently played by the display device 200 using a machine learning model, and automatically apply PQ parameters having scene pertinence according to the identified scene, thereby providing a better viewing experience for the user. The function is not limited by a third party service provider, can be used in any region, and has wider application range.

However, if there is an unrecognizable scene during the use of the AIPQ function, the display device 200 will use the pre-stored default PQ parameters for image display, however, the image displayed according to the default PQ parameters may not meet the experience requirement of the user for viewing the display device 200 in many cases. Therefore, the current display apparatus 200 also has a problem of affecting the user experience using the AIPQ function.

Based on the above problems, the embodiment of the application provides an image display method and a display device, which combine an intelligent image mode switching AIPQ function with an automatic content recognition ACR function, and when the intelligent image mode switching AIPQ function cannot recognize a scene, the scheme of the application can realize the display of a high-quality image without using default image parameters, ensure that a target image can meet the experience requirement of a user for watching the display device 200, and simultaneously avoid the conflict in the adjustment process of the image quality parameters when the AIPQ function and the ACR function are used simultaneously.

The display device 200 provided in the embodiment of the present application at least includes a display 275 and a controller 250, wherein the display 275 is used for displaying a target image that a user needs to watch, and the controller 250 is used for controlling the display device 200 to respond to a control instruction input by the user, setting an image quality parameter, displaying the target image according to the image quality parameter, and the like.

When the user wants to watch a certain image, an instruction is input to the display device 200 to adjust the content currently displayed by the display device 200, and the user can input an instruction to the display device 200 by pressing a key on the remote controller, or can input an instruction to the display device 200 by speaking the content to be selected to the display device 200.

After receiving the instruction from the user, the display device 200 selects the corresponding signal source channel to play the target image that the user wants to watch. In order to ensure that the quality of the target image can meet the user's requirements, as shown in fig. 6, the controller 250 needs to acquire the target image, then set the target image quality parameter corresponding to the target image by using the intelligent image mode switching AIPQ function and/or the automatic content recognition ACR function, and finally control the display 275 to display the target image according to the target image quality parameter. Generally, both the AIPQ function and the ACR function can match or calculate a series of image quality parameters for the identified content, which can make the target image displayed more clearly and the RGB brightness etc. of the image more optimized and the target image more realistic than the default image quality parameters in the display device 200.

The AIPQ function can identify the scene of the target image by using a machine learning model and match the scene to the image quality parameter with scene pertinence according to the scene. In practical application, some image quality parameters are set in advance corresponding to different scenes which can be identified by the AIPQ function. For example, the scene that can be identified by the AIPQ function includes a lawn, sky, face, building, etc., and then some better image quality parameters are respectively preconfigured for the lawn, sky, face and building, and if the scene of the target image is identified as the lawn, the AIPQ function can be matched with the image quality parameters corresponding to the lawn scene, so as to adjust the definition, contrast, RGB brightness, chromaticity, etc. of the lawn scene image, so that the lawn and other objects in the target image can be more vividly presented.

The ACR function can directly identify multimedia content using a computer algorithm, and then calculate a series of parameters corresponding to the content according to the identified content. The ACR function in the embodiment of the application is mainly used for identifying the content of the target image, and further calculates and sets some image quality parameters according to the identified content, for example, the ACR function is used for identifying the face, the grassland and the like in the target image, so that the ACR function can consider the color characteristics of the face and the grassland, further calculate the image quality parameters conforming to the characteristics of the face and the grassland, and adjust the display definition, contrast, RGB brightness, chromaticity and the like of the face and the grassland in the target image, and the things such as the face and the grassland are more vivid.

In some embodiments, as shown in fig. 7, after the target image is acquired, the controller 250 further needs to determine whether the target signal source where the target image is located exists in the signal source white list, so as to determine whether the display device 200 can currently set the target image parameter by using the AIPQ function. The use of the AIPQ function requires capturing an image currently displayed by the display device 200, but some third party applications, such as Netflix, amazon, youtube, may not allow capturing a video based on the Content of CSP (Content-Security-Policy), so the display device 200 cannot perform the AIPQ operation on copyrighted Content, and if the AIPQ operation is forced, it may cause complaints of the partner, causing legal problems. Based on this, a signal source not required by the CSP may be added to the signal source white list, and whether or not the content provided by the signal source allows the AIPQ operation is determined by determining whether or not the signal source exists in the white list. In the case where the target signal source exists in the signal source white list, the AIPQ function and/or the ACR function may be used to set the target image quality parameter, and then the controller 250 controls the display 275 to display the target image according to the target image quality parameter; if the target signal source does not exist in the signal source white list, the target signal source cannot support the AIPQ operation, the controller 250 can set the target image quality parameter only using the ACR function, and then the controller 250 controls the display 275 to display the target image according to the target image quality parameter.

In some embodiments, as shown in fig. 8, if the target signal source exists in the signal source white list, the controller 250 further continues to determine whether a scene of the target image can be identified using the AIPQ function. Because, although the machine learning model trained for the AIPQ function is based on a huge number of sample image scenes, it cannot be guaranteed that all scenes are necessarily covered, and further, the scenes that the AIPQ function can recognize are limited. For example, if only four scenes of grasslands, sky, faces and buildings are trained in the machine learning model, the AIPQ is not recognized for scenes other than the four scenes. If a scene of the target image can be recognized using the AIPQ function, the controller 250 may set a target image quality parameter using the AIPQ function and then control the display 275 to display the target image according to the target image quality parameter; if a scene of the target image is not recognized using the AIPQ function, the controller 250 is required to set a target image quality parameter using the ACR function and then control the display 275 to display the target image according to the target image quality parameter.

As shown in fig. 7, if the target signal source does not exist in the signal source white list, indicating that the target signal source cannot currently support the AIPQ function, the controller 250 may set the target image quality parameter using the ACR function. However, before using the ACR function, the controller 250 also needs to determine whether the ACR function of the display apparatus 200 is available, i.e., whether the ACR function on the display apparatus 200 is turned on. Typically, the display device 200 supporting the ACR function will display options of the ACR function on its setting interface, and the ACR function is turned off in a default state, if it needs to be turned on, the user needs to control the turn-on thereof by inputting a command.

In some embodiments, as shown in fig. 9, in the case where the target signal source does not exist in the signal source white list, the controller 250 continues to determine whether the ACR function of the display apparatus 200 is available, and if the ACR function is available, the controller 250 may set the target image quality parameter using the ACR function, and then the controller 250 controls the display 275 to display the target image according to the target image quality parameter; if the ACR function is not available, the controller 250 needs to acquire a preset image quality parameter in the display apparatus 200 as a target image quality parameter, and then control the display 275 to display the target image according to the target image quality parameter.

Aiming at the situation that the target signal source is not in the signal source white list and the ACR function is available, the embodiment of the application can directly utilize the ACR function to set the target image quality parameter under the situation that the AIPQ function is unavailable, so that the problem that the target image cannot meet the user requirement due to the fact that the default image parameter is used when the AIPQ function is unavailable is avoided.

As shown in fig. 8, if a scene of a target image can be recognized using the AIPQ function, the controller 250 can set a target image quality parameter using the AIPQ function. In some cases, however, the ACR function of the display apparatus 200 may be available, and if the ACR function is available, the controller 250 may set the target image quality parameter together using the AIPQ function and the ACR function, so that the image quality parameter can be optimized to the maximum.

Thus, in some embodiments, as shown in fig. 10, if a scene of a target image can be identified using the AIPQ function, a first image quality parameter corresponding to the target image should be set using the AIPQ function first, and the controller 250 controls the display 275 to display an image displayed at this time as an image to be processed according to the first image quality parameter. The controller 250 may then further continue to determine whether the ACR functionality of the display device 200 is available. If the ACR function is not available, the controller 250 directly uses the first image quality parameter set by the AIPQ function as a target image quality parameter, and the image to be processed at this time is the target image; if the ACR function is available, the controller 250 continues to set a target image quality parameter of the image to be processed using the ACR function, and then controls the display 275 to display the target image according to the target image quality parameter.

Aiming at the situation that the scene of the target image can be identified by utilizing the AIPQ function and the ACR function is available, the embodiment of the application can reuse the ACR function on the basis of the AIPQ function, and can optimize the image quality parameter to the greatest extent, so that the target image displayed according to the image quality parameter can meet the requirements of users.

In addition, the target image quality parameter is further set by the ACR function based on the previous setting of the image quality parameter by the AIPQ function, so that the problem of conflicting image quality parameter setting caused by overlapping of identification contents of the two functions when the controller 250 sets the image quality parameter of the same target image by the AIPQ function and the ACR function, respectively, can be effectively avoided.

As shown in fig. 8, if a scene in the target image is not recognized using the AIPQ function, the controller 250 can set the target image quality parameter only using the ACR function. In some cases, however, the ACR functionality of the display device 200 may not be available, such as if the functionality is off in a default state, and if no user has been controlling to turn on, the ACR functionality is not available at all times. Thus, in some embodiments, as shown in fig. 11, if a scene in the target image is not recognized using the AIPQ function, it may also continue to determine whether the ACR function of the display apparatus 200 is available before the controller 250 uses the ACR function. If the ACR function is available, the controller 250 may set a target image quality parameter using the ACR function, and then the controller 250 controls the display 275 to display the target image according to the target image quality parameter; if the ACR function is not available, the controller 250 needs to acquire a preset image quality parameter in the display apparatus 200 as a target image quality parameter, and then control the display 275 to display the target image according to the target image quality parameter.

Aiming at the situation that the AIPQ function can not identify the scene of the target image and the ACR function is available, the embodiment of the application can set the quality parameter of the target image by using the ACR function, thereby avoiding the problem that the target image can not meet the requirement of a user due to the default image parameter when the AIPQ function can not identify the scene.

Also, the AIPQ function on the display apparatus 200 may be controlled to be turned on or off. For example, if the user does not previously turn off the AIPQ function, the controller 250 adjusts the AIPQ function on the setup interface to an on state if it detects that the current target signal source is in the signal source whitelist; if the target signal source is not in the signal source white list, the AIPQ function on the setup interface is hidden, i.e., becomes unavailable.

As can be seen from the above, the display device 200 provided in the embodiment of the present application may set the target image quality parameter of the target image in combination with the AIPQ function and the ACR function, so that the target image finally displayed according to the target image quality parameter can meet the viewing requirement of the user. In addition, when the AIPQ function cannot identify the scene of the target image but the ACR function is available, the scheme of the embodiment of the application can also use the target image quality parameter set by the ACR function, avoid using the default image parameter, further realize the display of the high-quality image, ensure that the target image displayed according to the target image quality parameter can meet the experience requirement of the user for watching the display device 200, and avoid the conflict in the adjustment process of the image quality parameter when the AIPQ function and the ACR function are used simultaneously.

The embodiment of the present application also provides an image display method, which mainly includes the steps executed by the controller 250 in the foregoing embodiment, as shown in fig. 12, and the method mainly includes:

step S101, obtaining a target image to be watched by a user; step S102, an AIPQ function and/or an ACR function are switched by using an intelligent image mode to set a target image quality parameter corresponding to the target image; in step S103, the display 275 is controlled to display the target image according to the target image quality parameter.

In addition, in step S102, it may also be determined whether a target signal source where the target image is located exists in the signal source white list, whether a scene of the target image can be recognized by the AIPQ function, and whether the ACR function of the display apparatus 200 is available. And, different image quality parameter setting operations are performed according to different judgment results.

In some embodiments, in the event that the target signal source is not present in the signal source whitelist, a determination is made as to whether ACR functionality of the display device 200 is available. If the ACR function is available, the ACR function may be used to set a target image quality parameter, and then the display 275 is controlled to display the target image according to the target image quality parameter; if the ACR function is not available, a preset image quality parameter in the display apparatus 200 needs to be acquired as a target image quality parameter, and then the display 275 is controlled to display the target image according to the target image quality parameter.

In some embodiments, in the event that the target signal source is present in the signal source white list, a determination is also made as to whether a scene of the target image can be identified using the AIPQ function. If a scene of the target image can be recognized using the AIPQ function, the target image quality parameter can be set using the AIPQ function, and then the display 275 is controlled to display the target image according to the target image quality parameter; if the scene of the target image is not recognized by the AIPQ function, it is necessary to set a target image quality parameter by the ACR function and then control the display 275 to display the target image according to the target image quality parameter.

In some embodiments, in the case where the target signal source exists in the signal source white list and a scene of the target image can be identified using the AIPQ function, the AIPQ function should be used to set a first image quality parameter corresponding to the target image first, and the control display 275 displays the image displayed at this time as the image to be processed according to the first image quality parameter. Then, it may also be continued to determine whether the ACR function of the display apparatus 200 is available. If the ACR function is unavailable, the first image quality parameter set by the AIPQ function is directly used as a target image quality parameter, and the image to be processed is the target image at the moment; if the ACR function is available, the ACR function is continuously used to set the target image quality parameter of the image to be processed, and then the display 275 is controlled to display the target image according to the target image quality parameter.

In some embodiments, in the event that the target signal source is present in the signal source white list and the scene of the target image is not recognized using the AIPQ function, a determination is also made as to whether ACR functionality of the display device is available. If the ACR function is available, the ACR function may be used to set a target image quality parameter, and then the display 275 is controlled to display the target image according to the target image quality parameter; if the ACR function is not available, a preset image quality parameter in the display apparatus 200 needs to be acquired as a target image quality parameter, and then the display 275 is controlled to display the target image according to the target image quality parameter.

In the embodiment of the present application, the image display method shown in fig. 13 may also be formed by combining various results of whether the target signal source where the target image is located exists in the signal source white list, whether the scene of the target image can be identified by using the AIPQ function, and whether the ACR function of the display device 200 is available.

As shown in fig. 13, in the case where the target signal source does not exist in the signal source white list and the ACR function is available, the embodiment of the present application can directly set the target image quality parameter by using the ACR function when the AIPQ function is unavailable, so as to avoid the problem that the target image cannot meet the user requirement due to using the default image parameter when the AIPQ function is unavailable.

As shown in fig. 13, for the case that the AIPQ function is utilized to identify the scene of the target image and the ACR function is available, the embodiment of the present application can reuse the ACR function based on the AIPQ function, and can optimize the image quality parameter to the greatest extent, so that the target image displayed according to the image quality parameter meets the requirements of the user, and at the same time, the conflict occurring in the adjustment process of the image quality parameter when the AIPQ function and the ACR function are used simultaneously can be avoided.

As shown in fig. 13, for the case that the AIPQ function can not identify the scene of the target image and the ACR function is available, the embodiment of the present application can set the target image quality parameter by using the ACR function, so as to avoid the problem that the target image cannot meet the user requirement due to using the default image parameter when the AIPQ function cannot identify the scene.
