The kernel, shell, and file system together make up the basic operating system structure that allows users to manage files, run programs, and use the system. After power-on, the kernel is started, kernel space is activated, hardware is abstracted, hardware parameters are initialized, and virtual memory, a scheduler, signals and interprocess communication (IPC) are operated and maintained. And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.

Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs can be Window (Window) programs carried by an operating system, system setting programs, clock programs, camera applications and the like; or may be an application developed by a third party developer such as a hi program, a karaoke program, a magic mirror program, or the like. In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which is not limited in this embodiment of the present application.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), 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 for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining a display size, determining whether a status bar is available, locking a screen, intercepting a screen, controlling a display change (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included 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 core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

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

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

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains 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 uses the input operation as a confirmation operation, 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 to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the 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) that a user acts on a display screen, 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 (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

In some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: the system comprises 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 input from cable television, radio broadcasts, 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, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

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

At present, the display device 200 generally uses an ACR (Auto Content Recognition) function to collect displayed Content for Content Recognition, and finally uses the Content Recognition result for enhancing AQ (Audio Quality) and PQ (Picture Quality) of the display device 200, Content recommendation, and the like, so as to improve the experience of the user using the display device 200.

However, the ACR function has some disadvantages such as that its content recognition depends on a third party service provider, and for example, that the ACR function is supported only in a specific country, its use has a limitation, etc. In order to avoid the problems caused by the aforementioned disadvantages of the ACR function, some display apparatuses 200 currently use an AIPQ (intelligent image mode switching) function. The AIPQ function is to identify a scene of content currently played by the display device 200 using a machine learning model and automatically apply PQ parameters with scene specificity according to the identified scene, thereby providing a better viewing experience to a user. The function is not limited by a third party service provider and can be used in any region, and the application range is wider.

However, if there is an unrecognizable scene during the use of the AIPQ function, the display device 200 displays an image using the pre-stored default PQ parameter, but the displayed image according to the default PQ parameter often fails to satisfy the user's experience of viewing the display device 200. Therefore, the current display apparatus 200 also has a problem of affecting the user experience using the AIPQ function.

Based on the above problems, embodiments of the present application provide 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 present application does not need to use default image parameters, and can also achieve display of high-quality images, so as to ensure that a target image can meet the experience requirement of a user for watching the display device 200, and simultaneously avoid a conflict in the adjustment process of image quality parameters when the AIPQ function and the ACR function are used simultaneously.

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

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

After receiving the instruction of the user, the display device 200 may select a 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 requirements of the user, 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. In general, the AIPQ function and the ACR function can each match or calculate a series of image quality parameters for the recognized contents, which enable the target image to be displayed more clearly and the RGB brightness, etc. of the image to be optimized and to be more realistic than the default image quality parameters in the display device 200.

The AIPQ function may identify a scene of a target image using a machine learning model, and match image quality parameters with scene specificity according to the scene. In practical application, some image quality parameters are preset for different scenes that can be identified by the AIPQ function. For example, scenes that can be recognized by the AIPQ function include grasslands, sky, faces, buildings and the like, some better image quality parameters are configured in advance for the grasslands, the sky, the faces and the buildings respectively, and if the scene of the target image is recognized as the grasslands, the AIPQ function can be matched with the image quality parameters corresponding to the grasslands, so that the definition, the contrast, the RGB brightness, the chromaticity and the like of the grasslands are adjusted, and grasslands and other objects in the target image are more vivid.

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 then some image quality parameters are calculated and set 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 the color characteristics of the face and the grassland can be considered by the ACR function, and then the image quality parameters conforming to the characteristics of the face and the grassland are calculated, so that the definition, the contrast, the RGB brightness, the chroma and the like of the face and the grassland in the target image are adjusted, 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 a target signal source where the target image is located exists in a signal source white list, and further determines whether the display apparatus 200 can currently set the target image parameters by using the AIPQ function. The use of the AIPQ function requires intercepting an image currently displayed by the display apparatus 200, but some third-party applications such as Netflix, Amazon, Youtube, etc. may not allow video to be intercepted based on the Content of CSP (Content-Security-Policy), so that the display apparatus 200 cannot perform AIPQ operation on copyrighted Content, and if forced AIPQ operation may cause complaints from partners, causing legal problems. Based on this situation, the signal source that is not requested by the CSP can be added to the white list of signal sources, and whether the AIPQ operation is allowed by the signal source can be determined by determining whether the signal source exists in the white list. In the case where the target signal source exists in the signal source white list, the target image quality parameter may be set using the AIPQ function and/or 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 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 determines whether a scene of the target image can be recognized using the AIPQ function. Although the machine learning model for AIPQ function training is based on massive sample image scenes, all scenes cannot be guaranteed to be covered, and the scenes which can be identified by the AIPQ function are limited. For example, if only four scenes, i.e., grass, sky, face, and building, are trained in the machine learning model, AIPQ is not recognized for scenes other than these four scenes. If a scene of the target image can be recognized using the AIPQ function, the controller 250 can 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 the scene of the object image is not recognized using the AIPQ function, it is necessary that the controller 250 sets the object image quality parameter using the ACR function and then controls the display 275 to display the object image according to the object 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. In general, the display device 200 supporting the ACR function displays options of the ACR function on a setting interface thereof, and the ACR function is turned off in a default state, and if the ACR function needs to be turned on, the user needs to input an instruction to control the turning on of the ACR function.

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 does not exist 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, and the problem that the target image cannot meet the user requirement due to the fact that the target 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. However, in some cases, it is possible that the ACR function of the display apparatus 200 is available, and if the ACR function is available, the controller 250 can collectively set the target image quality parameter using the AIPQ function and the ACR function, thus enabling the image quality parameter to be optimized to the maximum extent.

Therefore, in some embodiments, as shown in fig. 10, if a scene of a target image can be recognized 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. Then, the controller 250 may also continue to determine whether the ACR function of the display apparatus 200 is available. If the ACR function is unavailable, the controller 250 directly uses the first image quality parameter set by the AIPQ function as the target image quality parameter, and the image to be processed is the target image; if the ACR function is available, the controller 250 continues to set the 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.

In view of the above situation that a scene of a target image can be identified by using the AIPQ function and the ACR function is available, the embodiment of the present application may reuse the ACR function on the basis of the AIPQ function, so as to optimize image quality parameters to the maximum extent, and further enable the target image displayed according to the image quality parameters to better meet the requirements of users.

In addition, the target image quality parameter is further set by using the ACR function on the basis of setting the image quality parameter by using the AIPQ function in advance, so that the problem of image quality parameter setting conflict caused by overlapping of the identification contents of the two functions when the controller 250 sets the image quality parameter of the same target image by using 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. However, in some cases, the ACR function of the display apparatus 200 may not be available, such as the function is off in a default state, and the ACR function is not available if there has been no user to control on. Accordingly, in some embodiments, as shown in fig. 11, if a scene in the target image is not recognized using the AIPQ function, it is also possible to continuously 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.

In view of the above situation that the scene of the target image cannot be identified by using the AIPQ function and the ACR function is available, the embodiment of the present application may set the target image quality parameter by using the ACR function, thereby avoiding a problem that the target image cannot meet the user requirement due to using the default image parameter when the scene cannot be identified by using the AIPQ function.

Also, the AIPQ function of the display device 200 may be controlled to be turned on or off at present. 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 is detected that the current target signal source is in the signal source white list; 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 requirements of the user. Moreover, 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 present application may also use the target image quality parameter set by the ACR function, thereby avoiding using the default image parameter, further realizing the display of the high-quality image, ensuring 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 simultaneously avoiding the conflict of the adjustment process of the image quality parameter when the AIPQ function and the ACR function are used simultaneously.

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

step S101, acquiring a target image which needs to be watched by a user; step S102, an intelligent image mode switching AIPQ function and/or an automatic content recognition ACR function are/is utilized to set target image quality parameters corresponding to the target images; 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 in which the target image is located exists in the signal source whitelist, whether a scene of the target image can be recognized using the AIPQ function, and whether the ACR function of the display apparatus 200 is available. And, according to different judging results, different image quality parameter setting operations are performed.

In some embodiments, in the case where the target signal source does not exist in the signal source white list, it is determined whether the ACR function of the display apparatus 200 is available. If the ACR function is available, the target image quality parameter may be set using the ACR function, 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, it is necessary 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 a target image according to the target image quality parameter.

In some embodiments, in the case where the target signal source is present in the signal source white list, it is also determined whether the scene of the target image can be identified using the AIPQ function. If the 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 object image is not recognized using the AIPQ function, it is necessary to set an object image quality parameter using the ACR function and then control the display 275 to display the object image according to the object image quality parameter.

In some embodiments, in the case that the target signal source exists in the signal source white list and the scene of the target image can be identified by using the AIPQ function, the first image quality parameter corresponding to the target image should be set by using the AIPQ function, and the display 275 is controlled to display according to the first image quality parameter, and the displayed image is taken as the image to be processed. Then, it is also possible to continuously determine whether the ACR function of the display apparatus 200 is available. If the ACR function is unavailable, directly using the first image quality parameter set by the AIPQ function as a target image quality parameter, wherein the image to be processed is the target image; 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 case where the target signal source exists in the signal source white list and the scene of the target image is not recognized using the AIPQ function, it is also determined whether the ACR function of the display device is available. If the ACR function is available, the target image quality parameter may be set using the ACR function, 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, it is necessary 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 a target image according to the target image quality parameter.

In the embodiment of the present application, an image display method as shown in fig. 13 may also be formed in combination with 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 recognized using the AIPQ function, and whether the ACR function of the display apparatus 200 is available.

As shown in fig. 13, for the case that the target signal source is not in the signal source white list and the ACR function is available, the embodiment of the application may 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 the use of default image parameters when the AIPQ function is unavailable.

As shown in fig. 13, for the situation that the scene of the target image can be identified by using the AIPQ function and the ACR function is available, the embodiment of the present application may reuse the ACR function on the basis of the AIPQ function, so as to optimize the image quality parameters to the maximum extent, and further enable the target image displayed according to the image quality parameters to better meet the requirements of the user, and simultaneously avoid the conflict of the adjustment processes of the image quality parameters when the AIPQ function and the ACR function are used simultaneously.

As shown in fig. 13, for the case that the target image cannot be identified by the AIPQ function and the ACR function is available, the embodiment of the present application may set the target image quality parameter by the ACR function, thereby avoiding 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.
