Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a display device and an image mode setting method. Background Technology

[0002] Display devices refer to terminal devices that can output specific display images. With the rapid development of display devices, their functions will become richer and their performance will become more powerful. They can realize two-way human-computer interaction functions and integrate multiple functions such as audio-visual, entertainment, and data to meet the diverse and personalized needs of users.

[0003] Users can use display devices to view media resources, such as movies and TV series, browse the internet, and play games. Display devices can also connect to external devices, such as game consoles, to receive media signals and display them to the user. To enhance the user experience, different image modes can be set for different tasks, such as movie mode, game mode, and photo mode. Users can configure the display device to various image modes to obtain different visual experiences.

[0004] However, external devices may send signals with special formats that have specific requirements for image quality and other parameters. If the display device uses the user-selected image mode to display this content, the image mode may not be compatible with the signal's display requirements, resulting in poor image quality and severely impacting the user experience. Summary of the Invention

[0005] This application provides a display device and an image mode setting method to solve the problem in related technologies where the image mode cannot adapt to the display requirements of the signal, resulting in poor picture quality and seriously affecting the user experience.

[0015] The media asset signal is parsed into a media asset image, and the display is controlled to show the media asset image.

[0016] As can be seen from the above technical solutions, some embodiments of this application provide a display device and an image mode setting method. When an external device sends a media asset signal to the display device, the display device can obtain the signal type of the media asset signal. If the signal type is a preset type, the display device can obtain the signal format information of the media asset signal. When the signal format information includes a target signal format, the display device sets the image mode to the target image mode; when the signal format information does not include a target signal format, the display device obtains historical image modes based on a preset user image mode database and sets the image mode to the historical image mode. The display device parses the media asset signal into a media asset image and displays the media asset image. For special target signal formats in the media asset signal, the display device can automatically adjust the image mode to adapt to them, so that the signal data can be displayed normally, improving the user experience.

[0030] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0031] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0032] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0033] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0034] The display device provided in this application can have various implementation forms, such as a television, a smart television, a laser projection device, a monitor, an electronic bulletin board, an electronic table, etc. Figure 1 and Figure 2 This is one specific embodiment of the display device of this application.

[0035] Figure 1 This is a schematic diagram illustrating the operational scenario between the display device and the control unit according to the embodiment. Figure 1 As shown, the user can operate the display device 200 through the smart device 300 or the control device 100.

[0036] In some embodiments, the control device 100 may be a remote control. Communication between the remote control and the display device includes infrared protocol communication, Bluetooth protocol communication, and other short-range communication methods, controlling the display device 200 wirelessly or via wired means. Users can control the display device 200 by inputting user commands through buttons on the remote control, voice input, control panel input, etc.

[0037] In some embodiments, a smart device 300 (such as a mobile terminal, tablet computer, computer, laptop computer, etc.) may also be used to control the display device 200. For example, an application running on the smart device may be used to control the display device 200.

[0038] In some embodiments, the display device may receive instructions not through the aforementioned smart devices or control devices, but through touch or gestures.

[0039] In some embodiments, the display device 200 can also be controlled in ways other than the control device 100 and the smart device 300. For example, it can be controlled by directly receiving the user's voice commands through a module configured inside the display device 200 for acquiring voice commands, or it can be controlled by receiving the user's voice commands through a voice control device set outside the display device 200.

[0040] In some embodiments, the display device 200 also communicates with the server 400. The display device 200 may communicate via a local area network (LAN), wireless local area network (WLAN), and other networks. The server 400 may provide various content and interactive features to the display device 200. The server 400 may be a cluster or multiple clusters, and may include one or more types of servers.

[0041] Figure 2 An exemplary block diagram of the configuration of the control device 100 according to an exemplary embodiment is shown. Figure 2 As shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface 140, a memory, and a power supply. The control device 100 can receive user input operation commands and convert the operation commands into commands that the display device 200 can recognize and respond to, thus acting as an intermediary for interaction between the user and the display device 200.

[0042] like Figure 3 The display device 200 includes at least one of the following: a tuner 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface.

[0043] In some embodiments, the controller includes a processor, a video processor, an audio processor, a graphics processor, RAM, ROM, and a first interface to an nth interface for input / output.

[0044] The display 260 includes a display screen assembly for presenting images, a driving assembly for driving image display, a component for receiving image signals from the controller output, and a user control UI interface for displaying video content, image content, menu control interface, and user control UI interface.

[0045] The display 260 can be an LCD display, an OLED display, or a projection display, and can also be a projection device and a projection screen.

[0046] The communicator 220 is a component used to communicate with external devices or servers according to various communication protocol types. For example, the communicator may include at least one of the following: a Wi-Fi module, a Bluetooth module, a wired Ethernet module, other network communication protocol chips or near-field communication protocol chips, and an infrared receiver. The display device 200 can establish the transmission and reception of control signals and data signals with the external control device 100 or the server 400 through the communicator 220.

[0047] The user interface can be used to receive control signals from the control device 100 (such as an infrared remote control).

[0048] Detector 230 is used to collect signals from the external environment or to interact with the external environment. For example, detector 230 includes a light receiver, a sensor for collecting ambient light intensity; or, detector 230 includes an image acquisition device, such as a camera, which can be used to collect external environmental scenes, user attributes, or user interaction gestures; or, detector 230 includes a sound acquisition device, such as a microphone, for receiving external sounds.

[0049] The external device interface 240 may include, but is not limited to, one or more of the following: High Definition Multimedia Interface (HDMI), analog or high-definition component input interface (component), composite video input interface (CVBS), USB input interface (USB), RGB port, etc. It may also be a composite input / output interface formed by multiple interfaces mentioned above.

[0050] The tuner / demodulator 210 receives broadcast television signals via wired or wireless means, and demodulates audio and video signals, such as EPG data signals, from multiple wireless or wired broadcast television signals.

[0051] In some embodiments, the controller 250 and the tuner 210 may be located in different separate devices, that is, the tuner 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0052] The controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200. For example, in response to receiving a user command to select a UI object to display on the monitor 260, the controller 250 can execute operations related to the object selected by the user command.

[0053] In some embodiments, the controller includes at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), RAM (random access memory), ROM (read-only memory), a first to an nth interface for input / output, a communication bus, etc.

[0054] Users can input commands through a graphical user interface (GUI) displayed on the monitor 260, and the user input interface receives the user input commands through the GUI. Alternatively, users can input commands by entering specific sounds or gestures, and the user input interface receives the user input commands by recognizing the sounds or gestures through sensors.

[0055] A "user interface" is the medium through which an application or operating system interacts and exchanges information with the user. It converts information from its internal form to a form that the user can accept. A common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed graphically. It can be an icon, window, control, or other interface element displayed on the screen of an electronic device. Controls can include visual interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets.

[0056] like Figure 4 As shown, the display device system is divided into three layers, from top to bottom: the application layer, the middleware layer, and the hardware layer.

[0057] The application layer mainly includes commonly used applications on TVs, as well as the application framework. The commonly used applications are mainly browser-based applications, such as HTML5 apps, and native apps.

[0058] An application framework is a complete program model that has all the basic functions required by standard application software, such as file access, data exchange, etc., as well as the user interface for these functions (toolbar, status bar, menu, dialog box).

[0059] Native apps can support online or offline access, push notifications, or access to local resources.

[0060] The middleware layer includes various television protocols, multimedia protocols, and system components. Middleware can use the basic services (functions) provided by system software to connect different parts of application systems or different applications on the network, achieving resource sharing and function sharing.

[0061] The hardware layer mainly includes the HAL interface, hardware, and drivers. The HAL interface is a unified interface for all TV chips, with the specific logic implemented by each chip. The drivers mainly include: audio drivers, display drivers, Bluetooth drivers, camera drivers, Wi-Fi drivers, USB drivers, HDMI drivers, sensor drivers (such as fingerprint sensors, temperature sensors, pressure sensors, etc.), and power drivers.

[0062] In some embodiments of this application, the display 260 may display a user interface. The user interface may contain a specific target image, such as various media resources obtained from a network signal source, including videos, images, and other content. The user interface may also be some UI interface of the display device, such as a system recommendation page.

[0063] Display devices can have various functions, such as browsing web pages, playing media, playing games, and video chatting, thus providing users with a wide variety of services. Users can control the display device to launch a specific application, thereby enabling the corresponding function.

[0064] In some embodiments, when the user controls the display device to power on, the controller 250 can control the display 260 to display the user interface. Figure 5 Schematic diagrams of user interfaces from some embodiments are shown. For example... Figure 5 As shown, the user interface includes a first navigation bar 500, a second navigation bar 510, a function bar 520, and a content display area 530. The function bar 520 includes multiple function controls such as "Viewing History," "My Favorites," and "My Applications." The content displayed in the content display area 530 changes according to the selected control in the first and second navigation bars 500 and 510. On the application panel page, users can click the "My Applications" control to input display commands for the application panel page, triggering entry into the corresponding application panel. It should be noted that users can also use other methods to select function controls to trigger entry into the application panel. For example, they can use voice control or search functions to control entry into the application panel page.

[0065] Users can view the applications installed on the display device through the application panel, which represents the functions supported by the display device. Users can select and open one of the applications to perform its functions. It should be noted that the applications installed on the display device can be system applications or third-party applications. By opening an application, users control the display device to perform the corresponding functions of that application. Figure 6 Schematic diagrams of the application panel in some embodiments are shown. For example... Figure 6 As shown, the application panel includes three controls: "Player," "Cable TV," and "Games." Users can click the "Player" control to open the player application on the display device. Users can perform various operations within the player, such as searching for media resources. Users can click the "Cable TV" control to watch various media channels on the display device, including programs provided by cable TV providers. Users can click the "Games" control to play games on the display device.

[0066] As users' demands for resource quality continue to rise, the current display device 200 provides users with professional parameter setting functions for resources such as Picture and Sound. Taking screen display as an example, the display device can be set with different image modes for different services. Image modes can include movie mode, game mode, photo mode, etc., and the picture parameters for each image mode can be different, including parameters such as brightness, color temperature, contrast, and backlight. Users can control the display device to be in different image modes to adjust the image quality of the displayed picture and thus obtain different visual effects.

[0067] In some embodiments, a user can actively select a specific image mode and set it as the currently operating image mode of the display device. The user can also input commands to the display device to query the image mode status, for example, by selecting relevant image mode options through the display device's system settings UI.

[0068] In response to the user's command, the controller can first count all image modes supported by the display device and generate an image mode setting interface. The controller can then control the monitor to display the image mode setting interface. Figure 7 Schematic diagrams of the image mode settings interface in some embodiments are shown. For example... Figure 7As shown, the image mode settings interface includes several image mode controls, each corresponding to an image mode supported by the display device. Image modes on the display device can include Standard Mode, Night Mode, Movie Mode, Game Mode, and Photo Mode. Standard Mode offers a more balanced set of screen parameters; for example, with a parameter range of 0-100, the screen parameter for Standard Mode can be set to 50. Night Mode protects the user's eyes by allowing for lower screen parameters such as brightness, for example, 20. Movie Mode, Game Mode, and Photo Mode are image modes set according to the display device's intended use, suitable for scenarios such as playing media, playing games, and browsing images, respectively.

[0069] In some embodiments, each image mode can have its own default image parameters; for example, all image parameters in the standard mode can be set to 50. Considering user experience, it can also be configured so that users can adjust the image parameters for each image mode themselves. For example, when a user selects the standard mode, they can also set the specific values ​​for each parameter in the standard mode. Figure 8 Schematic diagrams of image mode parameter adjustment interfaces in some embodiments are shown. For example... Figure 8 As shown, the display device's current image mode is set to standard mode. Users can adjust various parameters of standard mode, including brightness, color temperature, contrast, and backlight. For example, a user can adjust the brightness to 45. Users can also click the "Restore Default Settings" control to adjust all parameters of this image mode to their default settings.

[0070] In some embodiments, when a user uses the display device, they may switch the device's operating mode. For example, if the display device is playing media, the user can adjust the display device's image mode to movie mode. The user may also control the display device to enable game functionality and disable media playback. At this time, the display device can launch game-related applications. Since the display device is in movie mode, which is not suitable for game scenarios and may result in poor image quality, the user can switch the display device's image mode to game mode. Considering that manually switching image modes is too cumbersome, the display device can also be equipped with an automatic image mode switching function.

[0071] The display device can detect the current working environment and determine the appropriate image mode based on that environment, automatically switching to that mode to improve the user's viewing experience. The display device can be configured with an automatic image mode switching mode. When the display device enters this mode, it can activate the automatic image mode switching function to switch between image modes.

[0072] In some embodiments, a user can send an automatic image mode switching command to the display device by operating a designated button on the remote control. In practical applications, a pre-defined correspondence is established between the automatic image mode switching command and the remote control button. For example, an automatic image mode switching button is provided on the remote control. When the user touches this button, the remote control sends an automatic image mode switching command to the controller 250, at which point the controller 250 controls the display device to enter the automatic image mode switching mode. When the user touches the button again, the controller 250 can control the display device to exit the automatic image mode switching mode.

[0073] In some embodiments, a user can use the display device's sound acquisition device, such as a microphone, to send an automatic image mode switching command to the display device via voice input, thereby controlling the display device to enter the automatic image mode switching mode. The display device may be equipped with an intelligent voice system that can recognize the user's voice to extract the user's input commands.

[0074] In some embodiments, when a user controls a display device using a smart device, such as a mobile phone, they can also send an automatic image mode switching command to the display device. In practical applications, a control can be set up in the mobile phone, allowing the user to select whether to enter the automatic image mode switching mode, thereby sending the automatic image mode switching command to the controller 250. At this time, the controller 250 can control the display device to enter the automatic image mode switching mode.

[0075] You can also set an automatic image mode switching option in the UI of the display device. When the user clicks this option, they can control the display device to enter or exit the automatic image mode switching mode.

[0076] In some embodiments, to prevent users from accidentally triggering the automatic image mode switching mode, when the controller 250 receives the automatic image mode switching mode instruction, it can control the display 260 to display the automatic image mode switching mode confirmation information, thereby allowing the user to make a secondary confirmation as to whether to control the display device to enter the automatic image mode switching mode. Figure 9 A schematic diagram of automatic image mode switching confirmation information is shown in some embodiments.

[0077] In some embodiments, the controller can detect the operating scene of the display device in real time. When a change in the operating scene is detected, the controller can acquire the new operating scene and determine the corresponding image mode for that scene. For example, if the user instructs the display device to turn off media playback and start the game function while the display device is playing media, the controller can adjust the display device's image mode to game mode.

[0078] In some embodiments, users can use a display device to view media assets, including media assets stored locally on the display device and various media assets on the network. Due to the influence of the media asset source, each network media asset may have different requirements for picture parameters. For example, the source type may correspond to IMAX or Dolby, and their corresponding picture parameters are different. If the media assets are displayed using only the default movie mode, the user experience may be poor. Therefore, for different source types, the display device can also set corresponding image modes, such as Dolby mode and IMAX mode.

[0079] When a user instructs the display device to play media assets, the controller can detect whether the media asset is local or online. If it is local, the controller simply adjusts the display device's image mode to movie mode. If it is online, the controller can obtain the source information to determine the type of online media asset. For example, if the source provides Dolby-type media, the controller can adjust the display device's image mode to Dolby mode to adapt to the display requirements of online media assets and improve the user's viewing experience.

[0080] In some embodiments, the display device further includes an external device interface for connecting an external device, such as a gaming device. The display device and the external device establishing the communication connection act as the receiver (sink) and the transmitter (source), respectively. The external device can transmit data to the display device via the external device interface, sending media signals. For example, during gameplay, the user can output video and audio data in real time and send this data to the display device, which then outputs the video and audio data as images and sound. In this case, the gaming device acts as the transmitter, and the display device acts as the receiver.

[0081] Display devices and external devices have data interfaces with the same interface specification and function. For example Figure 10 As shown, both the display device and the external device are equipped with HDMI (High Definition Multimedia Interface). During use, users can plug both ends of the HDMI cable into the display device and the external device respectively, and after turning on both the external device and the display device, set the signal source of the display device to the HDMI interface, thereby enabling data transmission between the display device and the external device.

[0082] To achieve communication between the display device and external devices, other connection methods can be used, such as DVI (Digital Visual Interface), VGA (Video Graphics Array), and USB (Universal Serial Bus); wireless connections are also possible, such as Wi-Fi, Bluetooth, and infrared. Different communication connection methods can employ different data transmission protocols. For example, when using an HDMI interface, the HDMI transmission protocol can be used for data transmission.

[0083] It's important to note that the media asset signals sent from external devices to the display device may contain various signal formats, including some special formats such as filmmaker, HDR (High Dynamic Range), HDR10+, DOLBY, ALLM (Auto Low-latency Mode), SPD (Specific Product Description), and IMAX. These special signal formats have specific requirements for image display, such as certain requirements for image quality, contrast, and brightness. If these signal contents are displayed using only the display device's standard movie mode, the image mode will be unable to adapt to the signal's display requirements, resulting in poor image quality and severely impacting the user experience. Therefore, when an external device is connected to the display device, the controller can detect these special signals to adjust the display device's image mode, thereby improving the user's viewing experience.

[0084] Figure 11 The diagram illustrates the interaction flowcharts of various components of the display device in some embodiments, including the following steps:

[0085] S101. In response to the media asset signal sent by the external device, obtain the signal type of the media asset signal.

[0086] S102. Based on the detection that the signal type is a preset type, obtain the signal format information of the media asset signal.

[0087] S103. Based on the detection that the target signal format is included in the signal format information, the image mode of the display device is set to the target image mode. If the target signal format is not detected in the signal format information, historical image modes are obtained based on a preset user image mode database, and the image mode of the display device is set to the historical image mode.

[0088] S104. The media asset signal is parsed into a media asset image, and the display is controlled to show the media asset image.

[0089] Users can select a specific signal type, referred to as the target signal format in this embodiment. This target signal format can be set to "filmmaker," enabling the display device to perform specific detection so that when an external device sends this type of signal, the display device can switch to the corresponding image mode, improving the user experience.

[0090] In some embodiments, after detecting that the display device and the external device are connected, the controller can detect whether the external device sends a media asset signal to the display device.

[0091] If an external device sends a media asset signal to the display device, the controller can obtain the signal type of the media asset signal, which can include HDMI, USB, etc. The controller can detect whether the signal type and the model type corresponding to the target signal format are the same to determine whether the media asset signal can contain the target signal format. Taking the target signal format as FilmMaker as an example, the external device can input a FilmMaker signal to the display device via HDMI. Therefore, the model type corresponding to the target signal format is HDMI, and HDMI can be determined as the preset type.

[0092] The controller can detect whether the media asset signal type is HDMI. When the signal type is HDMI, it means that the media asset signal may contain the target signal format, and the controller can continue to detect whether the target signal format exists in the media asset signal.

[0093] In some embodiments, before acquiring the signal type of the media asset signal, the controller may first detect whether the media asset signal contains a video signal in order to determine whether the current media asset signal has a need to switch image modes.

[0094] Media assets may contain only video signals, only audio signals, or both video and audio signals.

[0095] When the media asset signal does not contain a video signal, since no image needs to be displayed, the display device does not need to switch image modes; the controller only needs to process the audio signal. The controller can parse the audio signal to obtain audio data. The display device can also be equipped with an audio output interface, through which audio devices, such as speakers, can be connected. The display device can also have built-in audio devices, such as loudspeakers. The controller can control the audio devices to play the audio data.

[0096] If the media asset signal contains a video signal, it means that the display device may need to switch image modes. In this case, the controller can obtain the signal type of the video signal.

[0097] In some embodiments, the controller can acquire signal format information of the media asset signal, which is used to characterize the signal format contained in the media asset signal. The controller can control an external device interface to detect the signal format contained in the media asset signal.

[0098] It should be noted that the media asset signals transmitted by external devices may or may not contain the target signal format, or they may contain other special signal formats, such as ALLM, SPD, IMAX, HDR, HDR10+, and Dolby. Each special signal format has different requirements for image display and presents different visual effects to the user. Compared to Filmmaker, ALLM, SPD, IMAX, HDR10+, and Dolby signal formats have more complex requirements for image parameters and have a greater impact on the user's viewing experience. Therefore, the priority of these special signal formats can be set higher than that of the target signal format. That is, when these special formats and the target signal format coexist, the display device's image mode can be preferentially set to the image mode corresponding to these special signal formats.

[0099] These special signal formats also differ in their impact on the user's viewing experience. Therefore, these special signal formats can be assigned priorities. In this embodiment, the special signal formats are assigned two priorities, referred to as a first type of signal format and a second type of signal format, respectively, with the first type of signal format having a higher priority than the second type of signal format. The first type of signal format and the second type of signal format can be set by technicians designing display devices.

[0100] In some embodiments, the first type of signal format and the second type of signal format can be determined based on the degree of difference between the special signal format and the target signal format. First, the image parameters of the image modes corresponding to each special signal format and the target signal format can be statistically analyzed. Then, the difference between the image parameters of the image modes corresponding to each special signal format and the image parameters of the image modes corresponding to the target signal format can be obtained. The special signal formats with the largest differences are determined as the first type of signal format, and the remaining special signal formats are determined as the second type of signal format.

[0101] In this embodiment of the application, ALLM, SPD, and IMAX are used as the first type of signal format, and HDR10+ and Dolby are used as the second type of signal format for analysis.

[0102] It should be noted that for the special signal format HDR, HDR and filmmaker can be set to have the same priority, meaning HDR does not need to be detected when detecting the first and second type signal formats. If neither the first nor the second type signal format exists in the media asset signal, the controller can detect the presence of an HDR signal. For the HDR format, the display device can be configured with an HDR image mode. The HDR image mode can include the HDR.filmmaker image mode, which is compatible with both HDR and filmmaker image modes, satisfying the requirements of both signal formats. Therefore, if both HDR and filmmaker are detected simultaneously, the controller can set the display device's image mode to the HDR.filmmaker image mode.

[0103] In some embodiments, the controller may obtain first type signal format status information based on the media asset signal. The first type signal format status information is used to characterize whether the media asset signal contains the first type signal format.

[0104] The controller can obtain the status value of the first flag bit corresponding to the first type of signal format in the media asset signal based on the external device interface. The external device interface itself can detect the signal format in the media asset signal, so the controller can control the external device interface to detect whether the media asset signal contains the first type of signal format. If it contains the first type of signal format, the external device interface can set the status value of the first flag bit corresponding to the first type of signal format to 1; if it does not contain the first type of signal format, the external device interface can set the status value of the first flag bit corresponding to the first type of signal format to 0.

[0105] In some embodiments, the external device can first determine whether the media asset signal contains a first type of signal format. If it contains the first type of signal format, it generates a first flag status value of 1; if it does not contain the first type of signal format, it generates a first flag status value of 0. The external device can then send the first flag status value and the media asset signal together to the display device.

[0106] The controller can determine whether the media asset signal contains the first type of signal format based on the status value of the first flag bit.

[0107] If the first flag value is 0, it is determined that the media asset information does not contain the first type of signal format; if the first flag value is 1, it is determined that the media asset signal contains the first type of signal format.

[0108] In some embodiments, if the media asset signal contains a first type of signal format, the controller can set the image mode of the display device to the image mode corresponding to the first type of signal format. For example, if the media asset signal contains an IMAX signal format, the controller can directly set the image mode of the display device to the IMAX image mode.

[0109] If the media asset information does not contain the first type of signal format, the controller can continue to detect whether the media asset signal contains the target signal format. The controller can obtain the target signal format status information based on the media asset signal. The target signal format status information is used to characterize whether the media asset signal contains the target signal format.

[0110] In some embodiments, when acquiring target signal format status information, the controller can obtain the second flag status value corresponding to the target signal format in the media asset signal based on an external device interface. If the second flag status value is 0, it can be determined that the media asset information does not contain the target signal format. If the second flag status value is 1, it can be determined that the media asset signal contains the target signal format.

[0111] The external device interface can automatically detect whether the media signal contains the target signal format, thereby generating a second flag status value. Alternatively, the external device can pre-determine whether the target signal format is included, thereby generating a second flag status value and sending it to the display device.

[0112] In some embodiments, based on the detection that the signal format information includes a target signal format, for example, if the second flag value is 1, the controller can set the image mode of the display device to the image mode corresponding to the target signal format, referred to as the target image mode in this embodiment. At this time, the screen parameters in the display device can meet the display requirements of the target signal format, thereby improving the user's viewing experience.

[0113] If the target signal format is not detected in the signal format information (e.g., the second flag value is 0), the controller can maintain the display device's image mode as the image mode previously set by the user. The controller can retrieve historical image modes based on a preset user image mode database and set the display device's image mode to the historical image mode.

[0114] It should be noted that the display device has a pre-set user image mode database. When a user manually selects a certain image mode for the display device, the controller can store that image mode in the user image mode database as a historical image mode. If the user changes the display device's image mode, the controller can update the historical image mode in the user image mode database to reflect the newly selected image mode.

[0115] In some embodiments, the display device may be equipped with a target signal format detection switch, which can control whether the display device can automatically enter the target image mode. When the target signal format detection switch is in the on state, the controller allows the display device to enter the target image mode; if the target signal format detection switch is in the off state, the controller does not allow the display device to enter the target image mode.

[0116] Once the controller detects that the target signal format is included in the signal format information, for example, if the second flag value is 1, it can obtain the status information of the target signal format detection switch in the display device.

[0117] If the target signal format detection switch is turned on, the controller can set the display device's image mode to the target image mode.

[0118] If the target signal format detection switch is off, the controller can maintain the display device's image mode as the last image mode set by the user, since the display device is not allowed to enter the target image mode. That is, when the target signal format detection switch is off, the controller can retrieve historical image modes based on a preset user image mode database and set the display device's image mode to the historical image mode.

[0119] In some embodiments, considering that the second type of signal format has a higher priority than the target signal format, the controller may first detect whether the media asset signal contains the second type of signal format before adjusting the image mode of the display device to the target image mode.

[0120] After detecting that the target signal format detection switch is in the on state, the controller can obtain the status information of the second type of signal format in the media asset signal based on the external device interface, which is used to characterize whether the media asset signal contains the second type of signal format.

[0121] If the media asset signal contains a Type II signal format, the controller can set the display device's image mode to the image mode corresponding to the Type II signal format. For example, if the media asset signal contains Dolby format, the controller will set the display device's image mode to Dolby mode.

[0122] If the media asset signal does not contain a second type of signal format, the controller can set the display device's image mode to the target image mode.

[0123] In some embodiments, considering that users may not know the state of the target signal format detection switch, the display device will not enter the target image mode when the target signal format detection switch is off. If the media asset signal contains the target signal format, it will affect the user's viewing experience. Therefore, when the target signal format detection switch is detected to be off, the controller can control the display to show the target signal format prompt interface. Figure 12 Schematic diagrams of target signal format prompt interfaces in some embodiments are shown. For example... Figure 12 As shown, the target signal format prompt interface includes a prompt message, a confirmation control, and a cancellation control. The prompt message indicates whether the target signal format detection switch is enabled, and may read, "The target signal format detection switch is currently disabled, and the display device cannot enter the target image mode. Please confirm whether to enable the target signal format detection switch."

[0124] In response to the user's selection of the deselection control, the controller can retrieve historical image modes based on a preset user image mode database and set the display device's image mode to the historical image mode.

[0125] In response to the user's selection of the confirmation control, the controller can turn on the target signal format detection switch and set the display device's image mode to the target image mode.

[0126] In some embodiments, after the control display device enters a certain image mode, the controller can parse the media asset signal to obtain the media asset image and control the display to display the media asset image.

[0127] After detecting that the external device has stopped sending media data signals, the controller can turn off the target signal format detection switch. Simultaneously, the controller can set the display device's image mode to the user-preset historical image mode, for example, by retrieving historical image modes stored in the user's image mode database and switching the image mode from the target image mode to the historical image mode.

[0128] In some embodiments, when the display device is in the target image mode, the user can also switch to other image modes. The user can enter a command to query the image mode to bring up the image mode settings interface where image modes can be switched.

[0129] In response to the user's selection of the target image mode control, the controller can set the image mode of the display device to the image mode corresponding to the target image mode control, which is referred to as the first image mode in this embodiment. At the same time, the controller can store the first image mode in the user image mode database, so that the historical image modes in the user image mode database are updated to the first image mode.

[0130] This application embodiment also provides an image mode setting method, the method comprising:

[0131] Step 1301: In response to the media asset signal sent by the external device, obtain the signal type of the media asset signal.
