Description

Display device and color gamut space dynamic adjustment method

The present application claims priority of chinese patent application entitled "a dynamic color gamut space adjustment method and display device" filed by chinese patent office on 18/8/2019 under application number 201910761462.8, which is incorporated herein by reference in its entirety.

Technical Field

The application relates to the technical field of smart televisions, in particular to a display device and a color gamut space dynamic adjusting method.

Background

The color gamut space, also called color space, refers to the range of colors that can be represented by display media such as screens, digital output devices, and print reproduction devices, and includes a plurality of color gamut standards, such as bt.709, bt.2020, etc. established by the ITU international telecommunication union for high definition television, depending on the application scenario. Due to the development of high-definition television display technology, the color gamut space of the television tends to be larger and larger.

Meanwhile, the smart television which is not limited to the display function is also developed, and the smart television can obtain additional functions through a built-in or external sensor, a control device and the like on the basis of the television. For example, a camera is built in a television to collect image data, and the collected image data is displayed on a screen of the television in real time in cooperation with software application in the television, so that functions of 'looking into a mirror', 'chatting while looking', and the like are realized.

However, limited to the hardware of the internal or external device, the color gamut space corresponding to the internal or external device may be different from the color gamut space displayed by the television. For example, the color gamut space of the built-in camera adopts the bt.709 standard, and the color gamut space of the television display is larger than the bt.709 standard. Such color gamut differences can cause some color distortions when the television displays images provided by the internal or external devices. For example, when an image of the bt.709 standard is displayed on a television set larger than the bt.709 standard, the color distortion of the red portion is serious.

Therefore, when the color gamut space of the image content corresponding to the built-in or external device is different from the color gamut space displayed by the television, color distortion may occur in the display effect, and the viewing experience of the user is affected.

Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

It should be noted that, in the embodiment of the present application, a dual-system display device is taken as an example for description, and it is obvious that the color gamut space dynamic adjustment method of the present application may also operate in a single-system environment. Therefore, based on the color gamut space dynamic adjustment method of the present application, those skilled in the art can think that the technical solution applied in any system environment falls within the scope of the present application without creative efforts.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

Fig. 6b schematically shows a configuration of an application in a display device according to an embodiment; as shown in fig. 6b, the application layer of the display device contains various applications that can be executed at the display device 200.

The application layer 3912 of the a-chip may include, but is not limited to, one or more applications such as: live television applications, media center applications, and the like. It should be noted that what applications are respectively contained in the a chip and the N chip is determined according to an operating system and other designs, and the application does not need to specifically limit and divide the applications contained in the a chip and the N chip.

The live television application program can provide live television through 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.

Optionally, the different view display areas are presented with different priorities, and the display priorities of the view display areas are different among the view display areas with different priorities. If the priority of the system layer is higher than that of the application layer, when the user uses the acquisition selector and picture switching in the application layer, the picture display of the view display area of the system layer is not blocked; and when the size and the position of the view display area of the application layer are changed according to the selection of the user, the size and the position of the view display area of the system layer are not influenced.

For convenience of maintenance, the installed application programs may be different in the subsystems corresponding to the a chip and the N chip, for example, the subsystem corresponding to the a chip may focus on improving the extended functions of the display device, such as live tv broadcast, video website client, instant messaging, etc., through the application programs; and the subsystems corresponding to the N chips may focus on the adjustment of the display device itself, such as intelligent brightness adjustment, intelligent color adjustment, picture enhancement, and the like.

Correspondingly, the a chip can be connected with hardware equipment corresponding to the extended application program, for example, an application program named "mirror" installed in a subsystem corresponding to the a chip, and the purpose is to acquire image signals through a camera built in the a chip and display the image signals on a screen in real time so as to achieve the mirror-looking effect. According to the industry specification of the camera, the supportable color gamut space is a fixed standard value, for example, the commonly used camera supports the color gamut space as bt.709, but with the display requirement of high definition video, the display technology is continuously developed, and the supportable color gamut space is generally higher than that of the camera, for example, the color gamut space of the 4k television is bt.2020 standard. Thus, the color gamut space to which the image provided by the "mirror" application belongs is bt.709, while the display color gamut space of the television is bt.2020, i.e. there is a color gamut space difference, which is likely to cause color distortion when the "mirror" application is used.

In order to alleviate the problem of color distortion, the application provides a display device and a color gamut space dynamic adjustment method. Fig. 8 is a schematic flow chart of a color gamut space dynamic adjustment method according to the present application. Referring to fig. 14, which is a schematic structural diagram of a display device according to the present application, as can be seen from fig. 8 and 14, the display device provided in the present application includes: the system comprises a camera, a display and a controller, wherein the camera is configured to collect environment image data, the display is configured to display a user interface, a communication connection is established between the controller and the display, the controller is configured to execute presentation of the user interface, and whether a currently started application is a camera-related application or not is judged. The default display color gamut space of the display is a first color gamut space, and the color gamut space to which the image provided by the camera-related application belongs is a second color gamut space different from the first color gamut space. If yes, converting the display color gamut space of the display into a second color gamut space.

Correspondingly, the color gamut space dynamic adjustment method provided by the application comprises the following steps:

s11: and acquiring the current starting application information.

According to the technical scheme, the starting condition of the application program can be monitored in real time through a predefined process so as to obtain the current starting application information. In the application, the current application starting information can be represented by the package name information.

For example, when any application program is started, the currently started application program is determined by acquiring the corresponding package name information. The package name information is a program description file preset according to the model state of the display device, and may be a segment of character string, and when the corresponding application program is started, the character string may be acquired in the system memory. For example, the package name information corresponding to the "mirror" program may be "com.

For a dual system display device, package name information corresponding to its application program may be stored in a package name set file created or stored by the second hardware system. The package name set file may be stored by a partition in the second hardware system. For example, in a subsystem corresponding to the N chip, a partition named tvconfig is divided in advance, and an XML file is stored in the tvconfig partition as a package name set file according to the model of the display device. The XML file stores package name information corresponding to each application program. The package name set file may be used for dynamic configuration to inform the a-chip that an application such as "mirror" needs to adjust the color gamut space after it is started.

In some embodiments of the present application, as shown in fig. 9, the step of obtaining name information of a currently-started application package further includes the following steps:

s101: the first hardware system acquires a package name set file from the second hardware system; the package name set file comprises package name information of all application programs and a color gamut space to which the provided image belongs;

s102: the first hardware system loads the package name set file to monitor the starting state of each application program according to the package name set file;

s103: and the first hardware system extracts the currently started application program package name information from the package name set file.

In this embodiment, the first hardware system corresponding to the a chip may extract the package name set file, that is, extract the XML file, from the second hardware system partition corresponding to the N chip. In order to facilitate the subsequent determination of the color gamut space to which the image provided by the application program belongs, in this embodiment, the package name information and the color gamut space to which the provided image belongs may be further preset in the package name set file. For example, for a "mirror" application, which corresponds to the information in the package name set file, "com.

Optionally, an Activity Monitor Service module may be configured in the first hardware system corresponding to the a-card chip. The module starts to operate after the system is started, and reads a package name set file in a second hardware system through an RPC communication interface so as to determine the application package name information needing to set a color gamut space. After the package name set file is obtained, the starting state of each application program can be monitored according to the package name set file. When any application program is started, the Activity Monitor Service module can extract the packet name information corresponding to the application program from the packet name set file according to the started application program. Further, information corresponding to the color gamut space to which the image provided by the application program belongs can be extracted from the package name set file.

In order to realize the above functions, a Message Trans Service module may be built in the second hardware system corresponding to the N chip, and after the start-up, packet name information of the "look-to-mirror" application is read from the data separation and stored in the memory for the first hardware system corresponding to the a card to perform subsequent judgment.

Since the N chip is a chip that focuses on the system control function itself, the second hardware system corresponding to the N chip may be a basic system. Further, the cloud server can communicate with a second hardware system corresponding to the N chip to realize the cloud service of the display device. Correspondingly, the first hardware system can realize the separation function of the N-card data through a mode of acquiring the package name set file through the second hardware system, so that the color gamut space needs to be adjusted by dynamically configuring which application programs, and when the application programs are updated, the cloud service is configured through the N-card system, so that the package name set file is updated in real time, and the subsequent application expansion is facilitated. In addition, the management mode of the package name set file can be realized, the package names acquired from the second hardware system corresponding to the N chips are adapted, the application programs are uniformly set, and each application program does not need to be set, so that management and control are facilitated.

Thus, as shown in fig. 10, in some embodiments of the present application, the method further comprises the steps of:

s104: the second hardware system creates a package name set file according to the currently installed application program, or acquires the package name set file from the cloud server;

s105: storing the package name set file;

s106: and sending the package name set file to the first hardware system through a communication interface.

In this embodiment, the package name set file may be automatically created by the second hardware system according to the currently installed application program, or may be uniformly configured by the cloud server. The cloud server can be used for uniformly managing the package name set file by a manufacturer so as to uniformly issue the updating service. After the package name set file is created or acquired, the second hardware system may store the package name set file, so that the file is sent to the first hardware system through the communication interface after each startup, and is used for the first hardware system corresponding to the a chip to perform judgment.

As can be seen, in this embodiment, the package name set file is completed by the second hardware system corresponding to the N card, and the update data can be directly obtained from the cloud server through the second hardware system, so as to continuously improve the package name set file. Meanwhile, the occupation of the memory space of the first hardware system can be reduced, so that the first hardware system can run the application program more smoothly.

In some embodiments of the present application, as shown in fig. 11, the second hardware system may update the package name set file to implement application expansion by the following steps:

s1041: the second hardware system acquires package name updating data from the cloud server;

s1042: modifying the stored package name set file according to the updating data;

s1043: and sending the modified package name set file to the first hardware system through a communication interface.

In this embodiment, the second hardware system corresponding to the N chips may obtain the update data of the package name set file in a manner of downloading from the cloud server, and the specific update manner may be periodically queried and downloaded by the second hardware system or may be uniformly issued in real time by the cloud server. After the update data is acquired, the second hardware system may modify the stored package name set file according to the acquired update data, and replace the package name information and the color gamut space data to which the image provided by the application program belongs in the package name set file. And after the data is replaced, after the system is started, the modified package name set file can be sent to the first hardware system through the communication interface, so that the first hardware system can perform subsequent judgment according to the modified package name set file, and the color gamut space to which the image provided by the application program belongs is determined.

S12: and judging whether the current started application is related to the camera or not, wherein the color gamut space to which the image provided by the related camera application belongs is a second color gamut space different from the default display color gamut space.

In the technical solution provided by the present application, the color gamut space to which the image provided by the currently-started application belongs is a first color gamut space that is the same as the default display color gamut space, or a second color gamut space that is different from the default display color gamut space. The first color gamut space is a default display color gamut space, and the application belonging to the first color gamut space is an application without the need of converting the color gamut space. For example, a "movie" application, a "live tv" application, etc., needs to be displayed through a wide color gamut in order to highlight the layering sense of picture colors, and therefore, the color gamut space to which an image provided by the movie application belongs should be the same as the display color gamut space, i.e., the maximum color gamut space supported by the display device. Therefore, according to the package name information "com.hisense.tv.movie" of the "movie" application, the color gamut space to which the image provided by the "movie" application belongs may be determined to be the first color gamut space.

The second color gamut space refers to a color gamut space different from the default display color gamut space, and needs to be subjected to color gamut conversion to obtain a better display effect, and the application of the second color gamut space can be various. For example, a "mirror" application is limited by the maximum color gamut space that can be provided by the camera hardware, and the maximum color gamut space supported by the "mirror" application may not reach the range of the display color gamut space, that is, the color gamut space to which the image belongs, which is provided by the "mirror" application, is different from the display color gamut space and is the maximum color gamut space that can be reached by the built-in or external device. Therefore, according to the packet name information "com.hisense.tv.mirror" of the "mirror" application, the color gamut space to which the image attribution provided by the "mirror" application is attributed can be determined as the second color gamut space.

It should be noted that, in the technical solution provided in the present application, the display color gamut space may be a color gamut space supported by the current display device, and the first color gamut space and the second color gamut space may be unified classifications performed on each application in advance. If the color gamut space to which the image provided by the application program belongs is the same as the display color gamut space, the corresponding application belongs to the first color gamut space; if the color gamut space to which the image provided by the application program belongs is different from the display color gamut space, the corresponding application belongs to the second color gamut space. For example, if the maximum color gamut space standard of the display device is bt.2020, then the application of non-bt.2020 color gamut space such as "look at the mirror" is assigned to the classification of the second color gamut space; and bt.2020 standard color gamut space applications such as "movie" or other applications without limitation to color gamut space belong to the category of the first color gamut space.

In the technical solution provided in the present application, the first color gamut space and the second color gamut space may also be two relative state classifications generated by comparing the color gamut space supported by the image provided by the application with the current display color gamut space, that is, the same image provided by the application in different use stages may belong to different color gamut spaces. For example, the currently launched application is "mirror" and the maximum color gamut space supported by the provided image is bt.709, and if the current display color gamut space is also bt.709, the color gamut space to which the image provided by the "mirror" application belongs at this time is the first color gamut space. For another example, if the currently launched application is "mirror" and the maximum color gamut space supported by the provided image is bt.709, and the current display color gamut space is bt.2020, then the color gamut space to which the image provided by the "mirror" application belongs is the second color gamut space.

In the technical scheme provided by the application, if the display device comprises the dual system, the color gamut space to which the image provided by the application program belongs can be determined through the first system corresponding to the a chip. The specific determination method may be that the first hardware system acquires packet name information corresponding to the currently started application program after monitoring the currently started application program. And according to the package name information, matching the color gamut space supported by the current application in the package name set file, and then determining whether the color gamut space to which the image provided by the current application belongs is a first color gamut space or a second color gamut space by comparing the color gamut space supported by the application program with the current display color gamut space.

In some embodiments of the present application, as shown in fig. 12, the step of determining whether the currently-started application is a camera related application includes:

s201: acquiring package name information of a currently started application;

s202: matching preset camera related application package name information according to the package name information;

s203: and if the package name information is the same as the package name information of the related application of the preset camera, determining that the current application program is the related application of the camera.

In this embodiment, matching may be performed between the package name information of the currently started application and preset package name information of the camera related application, and it is determined whether the current application is the camera related application according to a matching result. For example, if the packet name information of the currently started application is "com.

S13: and if so, converting the display color gamut space of the display into the second color gamut space.

In the technical scheme provided by the application, in order to relieve color difference, the display color gamut space of the display can be converted into the second color gamut space in a software mode. For example, the currently launched application is "look at the mirror", the maximum color gamut space supported by the application is bt.709, the current display color gamut space is bt.2020, and the image attribution color gamut space provided by the current application is determined to be the second color gamut space. At this time, an image provided by a "mirror" application is displayed by a wide color gamut display device, and color distortion easily occurs. Therefore, the display color gamut space can be set to be the second color gamut space by adjusting the display color gamut space of the display device, that is, the current display color gamut space of the display device is adjusted to be bt.709, so as to alleviate the color gamut space difference between the application program and the display device and alleviate the color distortion problem.

In the technical scheme provided by the application, if the display device is the above dual-system device, since the second hardware system corresponding to the N chip is mainly used for controlling and adjusting the system basic function, the display color gamut space can be adjusted to the second color gamut space through the second hardware system corresponding to the N chip. Optionally, a process, for example, an hstvos process, may be defined in the second hardware system, and the process may keep running in a background after the system is booted, and when the first hardware system corresponding to the a chip determines that the currently started application program needs to adjust the color gamut space, a setting signal may be transmitted through the RPC communication interface to activate the hstvos process to run and set, so as to adjust the display color gamut space to the second color gamut space.

It should be noted that the present application describes the dynamic adjustment method of the color gamut space by taking the "look-at-mirror" application startup procedure as an example. In practical applications, different adjustments to the display color gamut space may be performed according to specific application environments. For example, when the display device switches from a "mirror" application to a "movie" application, the display gamut space has been adjusted to bt.709 since to accommodate "mirror", whereas "movie" applications require a wide gamut to improve display quality and therefore also require the display gamut space to be restored back to the bt.2020 standard gamut space. That is, in some embodiments of the present application, the method further comprises: the second hardware system sets the display color gamut space as the second color gamut space through a setting interface; or the second hardware system sets the display color gamut space as the first color gamut space through the restoration interface.

In addition, for the display device provided by the application, the proportion of the number of the camera related applications to the number of all the applications is small, and the frequency of the corresponding applications is not high. In most cases, the display gamut space of the display device is not adjusted. Therefore, after the application program which needs to adjust the color gamut space is run, the display color gamut space can be automatically adjusted back to the first color gamut space, so that the display color gamut space is the maximum color gamut space supported by the display device.

That is, in some embodiments of the present application, as shown in fig. 13, the method further includes the steps of:

s401: receiving a stop instruction of the camera related application;

s402: and if the stop instruction is received, reducing the display color gamut space into the first color gamut space.

The stop instruction is an instruction automatically generated when the camera related application program is exited. For example, after running the "look mirror" application, the user exits the "look mirror" application. At this time, the first hardware system may determine the stop instruction generated when the "looking at mirror" application exits by detecting the running state of the application in the memory. The stop instruction can be generated by judging that the application package name information in the memory is no longer in an activated state; or by the operating state of the user controller, such as generating a stop instruction when detecting that an exit key of a television remote controller is pressed. In response to receiving the stop instruction, it may be determined whether the application program has exited, and if the application has exited, the display gamut space may be restored back to the default display gamut space.

Adjusting the display color gamut space for an application includes setting and restoring, which may occur when an application is opened, switched, and closed. The switching application program may have multiple situations, and corresponding control may be performed for different situations. For example, when the current display device is switched from the "mirror" application to the "movie" application, since the color gamut spaces of the images provided by the two applications are different, the second hardware system is required to adjust the display color gamut space to bt.2020 corresponding to the "movie" application; if the application switch on the current display device is from a "movie" application to a "mirror" application, then the second hardware system is required to adjust the display color gamut space from bt.2020 to bt.709; if the application switching on the current display device is from the movie application to the live television application, the display color gamut space does not need to be adjusted to improve the application switching speed because the color gamut spaces to which the images provided by the movie application and the live television application belong are the same.

In another embodiment of the present application, the environmental image data collected by the camera may be subjected to color gamut space conversion, so that the environmental image data conforms to the color gamut space of the display. Therefore, in the present application, the dynamic adjustment can also be performed according to the following steps:

s21: acquiring current starting application information and environment image data acquired by a camera;

s22: judging whether the current started application is related to the camera or not, wherein a color gamut space to which an image provided by the related camera application belongs is a second color gamut space different from a default display color gamut space;

s23: and if so, performing color gamut space conversion on the environment image data acquired by the camera.

Corresponding to the dynamic adjustment method of the color gamut space, an embodiment of the present application further provides a display device, configured to implement the adjustment method, where the display device includes: the system comprises a display, a camera and a controller, wherein the controller is in communication connection with the display, the display is configured to display a user interface and environment image data, and the display defaults to display a color gamut space as a first color gamut space; the camera is configured to collect environment image data, and a color gamut space to which an image provided by the camera belongs is a second color gamut space different from the first color gamut space; the controller is configured to execute presenting a user interface and determine whether a currently launched application is a camera related application; and if so, performing color gamut space conversion on the environment image data acquired by the camera.

The difference between this embodiment and the above embodiments is that this embodiment implements dynamic adjustment by performing color gamut space conversion on the environment image data collected by the camera. For example, colors in the image are transformed according to the default display color gamut space, thereby eliminating the difference between the ambient image data and the default display color gamut space and mitigating color differences.

Obviously, the application programs in the memory include the control program of the system itself, and an additional program and a third party application, etc. as an extension.

For example, a camera may be built in the display device to capture images. The camera is connected with the data processing device, sends the acquired image to the data processing device, and then carries out processing such as decoding through the data processing device so as to send the acquired image to the display screen for displaying.
