Alternatively, the user may input a user command through a specific sound or gesture, and the user input interface receives the user input command by recognizing the sound or gesture through a sensor.

In some embodiments, the "user interface" is a medium interface for interaction and information exchange between the camera application or operating system and the user, which realizes the conversion between the internal form of information and the form acceptable to the user.

In some embodiments, the system of the display device may include a kernel, a command parser (shell), a file system, and a camera application. The kernel, shell, and file system together constitute the basic operating system structure, which allows users to manage files, run programs, and use the system. After power-on, the kernel starts, activates the kernel space, abstracts the hardware, initializes hardware parameters, etc., runs and maintains virtual memory, schedulers, signals, and inter-process communication (IPC). After the kernel starts, the shell and the user camera application are loaded. After startup, the camera application is compiled into machine code to form a process.

Referring to Figure 4, in some embodiments, the system is divided into four layers, namely, from top to bottom, the camera application (Applications) layer (referred to as "application layer"), the camera application framework (Application Framework) layer (referred to as "framework layer"), the Android runtime (Android runtime) and system library layer (referred to as "system runtime library layer"), and the kernel layer.

In some embodiments, at least one camera application is running in the camera application layer, and these camera applications can be window programs, system settings programs, clock programs, etc. provided by the operating system, or camera applications developed by third-party developers. In specific implementations, the camera application packages in the camera application layer are not limited to the above examples.

The framework layer provides an application programming interface (API) and programming framework for the camera applications in the camera application layer. The camera application framework layer includes some predefined functions. The camera application framework layer is equivalent to a processing center, which determines the actions of the camera applications in the application layer. Through the API interface, the camera application can access system resources and obtain system services during execution.

As shown in Figure 4, the camera application framework layer in the embodiment of the present application includes managers, content providers, etc., wherein the manager includes at least one of the following modules: an activity manager (ActivityManager) is used to interact with all activities 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) is used to retrieve various information related to the camera application package currently installed on the device; a notification manager (NotificationManager) is used to control the display and clearing of notification messages; a window manager (Window Manager) is used to manage icons, windows, toolbars, wallpapers and desktop components on the user interface.

In some embodiments, the activity manager is used to manage the life cycle of each camera application and the usual navigation back function, such as controlling the exit, opening, and back of the camera 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.).

In some embodiments, the system runtime layer provides support for the upper layer, namely the framework layer. When the framework layer is used, the Android operating system will run the C/C++ library 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 FIG4 , the kernel layer includes 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.

The display device may have a touch interaction function, and the user can operate the host by simply touching the display with a finger, thus getting rid of the keyboard, mouse, and remote control operation, making human-computer interaction more straightforward. Based on the above-mentioned display device 200, the display device 200 can support the touch interaction function by adding a touch component 276. Generally, the touch component 276 can form a touch screen together with the display 260. On the touch screen, the user can input different control instructions through touch operations. For example, the user can input touch instructions such as click, slide, long press, double click, etc., and different touch instructions can represent different control functions.

In order to realize the above-mentioned different touch actions, the touch component 276 can generate different electrical signals when the user inputs different touch actions, and send the generated electrical signals to the controller 250. The controller 250 can extract features from the received electrical signals, thereby determining the control function to be executed by the user according to the extracted features.

For example, when a user inputs a click touch action at any program icon position in the application interface, the touch component 276 will sense the touch action and generate an electrical signal. After receiving the electrical signal, the controller 250 can first determine the duration of the level corresponding to the touch action in the electrical signal, and when the duration is less than the preset time threshold, it recognizes that the user input is a click touch instruction. The controller 250 then extracts the position feature generated by the electrical signal to determine the touch position. When the touch position is within the display range of the application icon, it is determined that the user has input a click touch instruction at the application icon position. Accordingly, the click touch instruction is used to execute the function of running the corresponding application in the current scenario, so the controller 250 can start running the corresponding application.

For another example, when the user inputs a sliding action in the media display page, the touch component 276 also sends the sensed electrical signal to the controller 250. The controller 250 first determines the duration of the signal corresponding to the touch action in the electrical signal. When it is determined that the duration is greater than the preset time threshold, the position change of the signal generation is judged. Obviously, for interactive touch actions, the position where the signal is generated will change, thereby determining that the user has input a sliding touch command. The controller 250 then determines the sliding direction of the sliding touch command based on the change in the signal generation position, and controls the page turning of the display screen in the media display page to display more media options. Furthermore, the controller 250 can also extract the sliding speed, sliding distance and other features of the sliding touch command, and control the page turning screen according to the extracted features to achieve a hand-following effect, etc.

Similarly, for touch commands such as double-click and long press, the controller 250 can extract different features, determine the type of touch command through feature judgment, and then execute the corresponding control function according to the preset interaction rules. In some embodiments, the touch component 276 also supports multi-touch, so that the user can input touch actions on the touch screen through multiple fingers, such as multi-finger click, multi-finger long press, multi-finger slide, etc.

For some display devices with larger screen sizes, it is difficult for users to touch all areas of the screen, resulting in the inability to control the entire screen. For example, in some application scenarios, the display device needs to be mounted on a wall or a bracket. At this time, the user may not be able to touch the upper area of the screen, resulting in the inability to control the area, which seriously affects the user experience. For another example, if the display device is placed directly on the ground, if the user wants to touch the lower area of the screen, he needs to lower his body to touch, resulting in a poor user experience.

The present application provides a display device, including a display and a controller. FIG5 shows an interaction flow chart of various components of the display device in some embodiments.

The display is used to display the target image. The target image can be a media resource obtained from a network signal source, such as a video, a picture, or some UI interface of a display device, such as a user interface. The user can use the display device to play the target image. FIG6 shows a schematic diagram of displaying a target image in a display in some embodiments.

In some embodiments, considering that the user may not be able to manipulate the entire display area of the display, the display may display the target image only in a portion of the display area, that is, the display device may have a partial display function.

The display device may be provided with a partial display mode. When the display device is in the partial display mode, the controller may control a partial display area in the display to display the target image, and other display areas may be in a black screen state.

When the target image is displayed in the display, for example, when the display displays the target image in full screen mode, the user can send a partial display instruction to the display device, and the partial display instruction is an instruction to instruct to change the display area in the display. When the display device receives the partial display instruction, it can enter the partial display mode and display the target image in the partial display area of the display.

In some embodiments, the user can send a partial display mode instruction to the display device by operating a designated button of the remote control. In the actual application process, the correspondence between the partial display mode instruction and the remote control button is pre-bound. For example, a partial display mode button is set on the remote control. When the user touches the button, the remote control sends the partial display mode instruction to the controller, and the controller controls the display device to enter the partial display mode. When the user touches the button again, the controller can control the display device to exit the partial display mode.

In some embodiments, the correspondence between some display mode instructions and multiple remote control buttons can also be pre-bound. When the user touches multiple buttons bound to the partial display mode instructions, the remote control issues the partial display mode instructions. In a feasible embodiment, the buttons bound to the partial display mode instructions are the direction keys (left, down, left, down) in sequence, that is, when the user touches the buttons (left, down, left, down) continuously within a preset time, the remote control sends the partial display mode instructions to the controller. The above binding method can avoid the issuance of partial display mode instructions due to user misoperation. The embodiments of the present application only provide several exemplary binding relationships between partial display mode instructions and buttons. In the actual application process, the binding relationship between the partial display mode instructions and buttons can be set according to the user's habits, and no excessive restrictions are made here.

In some embodiments, the user can use a sound collector of the display device, such as a microphone, to send a partial display mode instruction to the display device by voice input to control the display device to enter a partial display mode. An intelligent voice system may be provided in the display device, and the intelligent voice system may recognize the user's voice to extract the content of the instruction input by the user. The user can input a preset wake-up word through the microphone to start the intelligent voice system, so that the controller can respond to the instruction input by the user. And input a partial display mode instruction within a certain period of time so that the display device enters a partial display mode. For example, the user can enter "classmate XX" to start the intelligent voice system. Then enter "enter partial display mode" to send a partial display mode instruction to the display device.

In some embodiments, the user can also send part of the display mode instructions to the display device through a preset gesture. The display device can detect the user's behavior through an image collector, such as a camera. When the user makes a preset gesture, it can be considered that the user has sent part of the display mode instructions to the display device. For example, it can be set as follows: when it is detected that the user draws a V, it is determined that the user has input part of the display mode instructions to the display device. The user can also send part of the display mode instructions to the display device through a preset action. For example, it can be set as follows: when it is detected that the user lifts up his left foot and right hand at the same time, it is determined that the user has input part of the display mode instructions to the display device.

In some embodiments, when a user uses a smart device to control a display device, such as a mobile phone, a partial display mode instruction may also be sent to the display device. In actual application, a control may be set in the mobile phone, through which a user may select whether to enter a partial display mode, thereby sending a partial display mode instruction to the controller, and the controller may control the display device to enter a partial display mode.

In some embodiments, when a user uses a mobile phone to control a display device, a continuous click instruction can be issued to the mobile phone. A continuous click instruction means that within a preset period, the number of times the user clicks on the same area of the mobile phone touch screen exceeds a preset threshold. For example, when a user clicks on a certain area of the mobile phone touch screen three times in a row within 1 second, it is regarded as a continuous click instruction. After receiving the continuous click instruction, the mobile phone can send a partial display mode instruction to the display device so that the controller controls the display device to enter the partial display mode.

In some embodiments, when a user uses a mobile phone to control a display device, it can also be set as follows: when it is detected that the touch pressure value of a certain area of the mobile phone touch screen by the user exceeds a preset pressure threshold, the mobile phone can send a partial display mode instruction to the display device.

A partial display mode option may also be set in the UI interface of the display device. When the user clicks on the option, the display device may be controlled to enter or exit the partial display mode.

In some embodiments, to prevent the user from accidentally triggering the partial display mode, when the controller receives the partial display mode instruction, it can control the display to display partial display mode confirmation information, so that the user can make a second confirmation whether to control the display device to enter the partial display mode. Figure 7 shows a schematic diagram of displaying partial display mode confirmation information in some embodiments.

When the display device enters the partial display mode, the controller may control the display to switch from a state in which the target image is displayed in the full screen mode to a state in which the target image is displayed in the partial display area.

In some embodiments, when the display device enters a partial display mode, the controller can control the display to update the display target image in the first area, and at the same time, can also make the target image not be displayed in the second area of the display. The first area can be a part of the display area pre-set by the user, and the second area is all the display areas of the display except the first area. That is, the controller can make the display area set by the user in the display display display an image, and all the display areas other than the user setting not display an image.

When setting the first area, it can be set according to the needs of the user. For example, for a display device mounted on a wall or a bracket, due to the high height, the user may not be able to touch the upper display area of the display. In this case, the first area can be set as the lower display area of the display to ensure that the user can touch. When setting the first area, it can be based on the area that the user can touch.

The size of the first area can also be set by the user, for example, the lower half of the display can be set to be the first area. Fig. 8 shows a schematic diagram of some display modes in some embodiments.

In some embodiments, when the display device enters the partial display mode, the target image can be updated in the first area of the display. When updating the target image, the controller can control the first area to display the entire target image, or control the first area to display only a portion of the target image.

In some embodiments, when the controller controls the first area to display the entire image of the target image, the size information of the first area may be first acquired. For example, the width of the first area is w1, and the height is h1.

Since the first region needs to display the entire target image, but the size information of the first region and the target image may be different, for example, the resolutions of the two are different, in order to improve the user's viewing experience, the target image may be scaled so that the target image better matches the first region.

The controller may first obtain the size information of the target image, for example, the width of the target image is w2 and the height is h2. At this time, the ratio of the width and height between the first area and the target image may be calculated respectively. The width ratio is p1=w1/w2, and the height ratio is p2=h1/h2.

Considering that the first area may not be in a standard size format, in order to ensure the image effect, the size ratio of the target image can be kept unchanged, that is, the ratio of the width and height of the target image can be kept unchanged. At this time, the size relationship between the width ratio p1 and the height ratio p2 can be compared, and the smaller ratio can be used as the scaling ratio of the target image.

For example, the resolution of the target image is 540*270, and the resolution of the first area is 2160*540. By calculation, the width ratio p1=2160/540=4 and the height ratio p2=540/270=2 are obtained. Therefore, 2 is selected as the scaling ratio, that is, the controller can enlarge the target image by 2 times to obtain a 1080*540 target image, and the controller controls the first area to display the 1080*540 target image.

At this time, the user can manipulate the entire target image through the first area. Fig. 9 is a schematic diagram showing the entire image of the target image displayed in the first area in some embodiments.

In some embodiments, the controller may also control the first area to display only a partial image of the target image. In this case, the display ratio of the target image itself remains unchanged and no scaling process is required. For example, when the first area of the display device is the lower half of the display, the image in the second area in full screen mode may be displayed in the first area, that is, the upper half of the target image is displayed. In full screen mode, the user may only be able to touch the lower half of the display, that is, only the lower half of the target image can be touched, and the upper half of the target image cannot be touched. When the display device enters partial display mode, the image in the original second area, that is, the upper half of the target image, may be displayed in the first area. At this time, the user can touch the upper half of the target image, thereby realizing that all images of the target image are touched.

In some embodiments, when the controller controls the first area to display only a partial image of the target image, the target image may be intercepted to obtain a partial image and displayed in the first area.

Specifically, the controller may first obtain the size ratio of the first area relative to the display, which is set as the first size ratio in the embodiment of the present application. Assume that the size information of the display is: width panel.width, height panel.heigh. The controller may determine the size information of the first area. For example, when the first area is the lower half of the display, its width is panel.width, and its height is panel.heigh/2. Therefore, the size ratio of the first area relative to the display is: width ratio 1, height ratio 0.5. That is, the first area is half the size of the display.

When the size ratio is obtained, a partial image with the same size ratio can be intercepted from the target image as the first image. It should be noted that the size ratio of the first image relative to the target image and the size ratio of the first area relative to the display are the same.

After the first image is acquired, the first image may be displayed in the first area.

In some embodiments, the position of the first image in the target image may also be determined according to the first area, that is, how to intercept the target image may be determined.

Specifically, the controller may first obtain the position information of the first area relative to the display. For example, when the first area is the lower half of the display, its position information is set to the bottom. When the first area is the left half of the display, its position information is set to the left.

After the position information of the first area is determined, the associated area in the target image can be determined according to the position information. The associated area is the area that needs to be selected when the target image is intercepted. There is a corresponding relationship between the first area and the associated area, and the corresponding relationship can be a relationship preset by the user.

The first area and the associated area may be areas opposite in orientation, for example, when the first area is the lower area of the display, the associated area is set to the upper area of the target image, and when the first area is the left area of the display, the associated area is set to the right area of the target image.

After the associated region is determined, a region corresponding to the first size ratio may be intercepted in the associated region to obtain a first image.

In some embodiments, when the first area is the lower half of the display, the position information of the first area can be determined to be the bottom of the display, the first size ratio is 1 for width, and 0.5 for height. According to the preset corresponding relationship, the associated area can be determined to be the upper area of the target image. At this time, the upper part of the target image can be obtained by intercepting the upper part of the target image according to the first size ratio. The controller can further display the upper part of the target image in the first area, that is, the lower half of the display. Figure 10 shows a schematic diagram of a first image of a target image displayed in the first area in some embodiments.

In some embodiments, after the target image is updated in the first region, the controller can control the display to display a first region adjustment control, which can adjust the region range of the first region and can be located at the edge of the first region. FIG11 shows a schematic diagram of the first region adjustment control in some embodiments.

The user can adjust the area range of the first area by touching the first area adjustment control. For example, the user can click the first area adjustment control and drag the control. When the user drags the control to a certain position, the user can stop clicking. At this time, the adjusted first area can be determined according to the position of the control after dragging.

Specifically, when a user touch operation on the first region adjustment control is detected, the controller can determine a movement track of the first region adjustment control, determine the current first region based on the movement track and the first region before adjustment, and set the current first region as the third region.

In some embodiments, the controller can detect the location information of the moving track. The user can control the first area adjustment control to drag in the first area, and the area range of the first area can be reduced. The user can also control the first area adjustment control to drag in the second area, thereby increasing the area range of the first area.

When the movement track is detected in the first area, it means that the user wants to reduce the area range of the first area. At this time, the controller can determine that the third area is the display area of the first area except the movement track, that is, the third area = the first area - the movement track. Figure 12 shows a schematic diagram of the third area in some embodiments.

When the movement track is detected in the second area, it means that the user wants to increase the area range of the first area. At this time, the controller can determine that the third area is the display area composed of the first area and the movement track, that is, the third area = the first area + the movement track. Figure 13 shows a schematic diagram of the third area in some embodiments.

After the third area is determined, the target image may continue to be updated and displayed in the third area.

In some embodiments, if in the previous setting, the first area displays a partial image of the target image, that is, the first image, after detecting the user's touch operation on the first area adjustment control, the third area can be acquired. At the same time, the image in the third area needs to be updated.

Specifically, the second size ratio of the third area to the display may be obtained, and the target image may be intercepted according to the second size ratio to obtain a new first image, which is set as the second image, wherein the size ratio of the second image to the target image is the same as the second size ratio.

After the second image is determined, the second image may be displayed in the third area.

It should be noted that the method of intercepting the target image according to the second size ratio and the method of updating and displaying the target image in the third area can refer to the aforementioned process and will not be described in detail here.

In some embodiments, if the first area displays the entire target image in the previous setting, after detecting the user's touch operation on the first area adjustment control, the third area can be acquired, and the image in the third area needs to be updated.

Specifically, the size information of the third area may be obtained, and the target image may be scaled according to the size information of the third area. Furthermore, the controller may display the scaled target image in the third area.

It should be noted that the method of scaling the target image according to the size information of the third area and the method of updating and displaying the target image in the third area can refer to the aforementioned process and will not be described in detail here.

In some embodiments, when setting the first area to display a partial image of the target image, when intercepting the target image, the first image may also be determined using the coordinate information of the first area.

Assume that the size information of the display is: width panel.width, height panel.heigh. At this time, a two-dimensional coordinate system can be established based on the display. For example, the left bottom point of the display is set as the origin, the rightward direction along the width direction is the X axis, and the upward direction along the height direction is the Y axis. At the same time, the coordinates of the right vertex of the display are set to (x, y). Therefore, the position information of the display is (0, 0), (0, y), (x, 0), (x, y). The area of the display is the area between the four coordinates.

Assume that the size information of the target image is: width video.width, height video.heigh. At this time, a two-dimensional coordinate system can be established according to the target image. In order to facilitate the determination of the position information of the first image directly according to the position information of the first area, the left bottom point of the target image can be set as the origin, the right along the width direction is the X axis, and the upward along the height direction is the Y axis. At the same time, the coordinates of the right vertex of the target image are set to (x, y). Therefore, the position information of the target image is (0, 0), (0, y), (x, 0), (x, y). The area of the target image is the area between the four coordinates. Setting the coordinate system of the display and the coordinate system of the target image to be the same can facilitate the determination of the position information of the first image.

The controller can further determine the position information of the first area. For example, the width of the first area is panel.width, the height is a*panel.heigh, 0<a<1, and the first area is located in the lower area of the display. Therefore, the position information of the first area can be determined as (0, 0), (0, a*y), (x, 0), (x, a*y). The first area is the area between these four coordinates. Figure 14 shows a schematic diagram of the coordinate information of the first area in some embodiments.

After determining the position information of the first area, it can be preliminarily determined that the first image is located at the position of the target image, that is, the associated area is determined. When the first area is located in the lower area of the display, it can be determined that the first image is located in the upper area of the target image. At the same time, the size ratio of the first image relative to the target image is the same as the size ratio of the first area relative to the display, so the position information of the first image can be determined above the target image, which is (0, y-a*y), (0, y), (x, y-a*y), (x, y). The first image can be obtained by intercepting the area between these four coordinates. Figure 15 shows a schematic diagram of the coordinate information of the first image in some embodiments.

After the first image is captured, the first image may be displayed in the first area.

In some embodiments, the display device is in partial display mode, and when a partial image of the target image is displayed in the first area, the user can touch the image that was previously untouchable in the first area. For example, when the first area is the lower half of the display, the upper half of the target image can be displayed, and the user can touch the upper half of the target image. If the user needs to touch the lower half of the target image, the display device can be controlled to exit the partial display mode and enter the full-screen display mode. At this time, the lower half of the target image is displayed in the first area, and the user can touch it.

Alternatively, when the entire target image is displayed in the first area, the user may feel that the size of the currently displayed target image is small and the image viewing experience is poor. At this time, the display device can also exit the partial display mode and enter the full-screen display mode.

In some embodiments, when the display device enters the partial display mode, the controller can control the display to display a recovery control, where the recovery control is used to control the display device to exit the partial display mode and restore the full screen mode.

When a user triggering operation on the restore control is detected, such as when the user clicks the restore control, the display device may exit the partial display mode, and the controller may control the display to display the target image in full screen mode.

In some embodiments, when the display device enters the partial display mode, the user can exit the partial display mode by touching the second area.

Specifically, when a user touch operation on the second area is detected, such as the user clicking the second area or sliding a finger in the second area, the display device can exit the partial display mode, and the controller can control the display to display the target image in full screen mode.

The present application also provides an image display method, which is applied to a display device. As shown in FIG16 , the method includes:

Step 1601: When it is detected that a target image is displayed in the display, in response to an instruction input by a user to change the display area in the display, the target image is updated in the first area of the display, and the target image is controlled not to be displayed in the second area of the display; the first area is a preset display area, and the second area is other display areas in the display except the first area.
