Description

Display equipment, camera priority use control method and device

The present application claims priority of chinese patent application with application number 201910761456.2, entitled "control method and apparatus for priority use of camera, and display device" filed in 2019 on 18/8.2019, which is incorporated herein by reference in its entirety.

Technical Field

The application relates to the technical field of camera control, in particular to a display device, and a control method and device for priority use of a camera.

Background

With the rapid development of smart televisions, the functions of the televisions are more and more abundant, and the performance of the televisions is more and more powerful. For example, the smart tv may implement functions of web search, IP tv, BBTV web-tv, Video On Demand (VOD), digital music, web news, web video telephony, etc. When the network video call function is realized, a camera needs to be installed on the intelligent television, so that the image of a user is acquired.

At present, applications requiring a camera on the smart social television include "hi sight", "look at mirror", "excellent cat", and the like, and functions of "chatting while watching" and "chatting while learning" can be realized. "hi" is a video chat application that enables one-touch chat between a mobile phone and a television, and between a television and a television. The mirror viewing application is an application for providing a mirror service for a user, and the user can use the smart television as a mirror by turning on the camera through the mirror viewing application. The "best learning cat" is an application that provides learning functions. When the function of 'chatting while learning' is realized, the user starts the 'cat excel' application to learn in a scene of starting the 'hi' application to perform a video call. When the function of "chatting while learning" is realized, the user simultaneously views the video program in a scene where the "hi" application is activated to perform a video call.

However, since the camera can only be used by one application after being activated, for example, when the application in which the camera is used at the same time is a video call, a mirror application or other applications, the camera can only be used for the video call, or can only be used for the mirror, or can be used for other applications. It can be seen that, when using intelligent TV, there is the condition that a plurality of applications called the camera simultaneously, this moment because can't use the camera simultaneously between a plurality of applications, easily causes the use of camera to appear the confusion.

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.

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.

Since the a-chip and the N-chip may have independent operating systems installed therein, there are two independent but interrelated subsystems in the display device 200. The chip A is in communication connection with the chip N, the chip N is in communication connection with a display screen of the smart television, the remote controller sends an operation instruction to the chip A through the Bluetooth module, and the chip A sends the operation instruction to the chip N so as to control a display interface of the display screen of the smart television. The chip A is connected with a camera, and the lifting of the camera is controlled by a motor. The picture that the camera was gathered is transmitted to N chip by A chip, and then is shown the picture on the display screen by N chip. Because the application that can use the camera all exists in dual system (A chip and N chip) for when using intelligent TV, there is the condition that a plurality of applications call the camera simultaneously, because can't use the camera simultaneously between a plurality of applications this moment, easily cause the use of camera to appear the confusion.

Therefore, in order to make the use of the camera more smooth, the present embodiment provides a display apparatus for performing a control method of priority use of the camera, which makes a priority determination on an application that can use the camera, and an application with a high priority can use the camera with priority.

Fig. 8 is a flowchart illustrating a control method according to priority use of a camera in an embodiment.

Referring to fig. 8, in the display device according to the embodiment of the present application, when the control method for priority use of the camera shown in fig. 8 is executed, the execution subject is a camera service (a-card camera service) in the first hardware system, and the camera service is configured in the controller. The A card camera service is used for realizing the connection between the camera and the camera application, the camera application comprises the camera application in the first hardware system and the camera application in the second hardware system, and the camera application refers to the application in the dual system (the first hardware system and the second hardware system) which needs to use the camera to realize corresponding functions. In particular, the controller, when executing the method, comprises the steps of:

and S1, receiving a first calling request for calling the camera.

The condition that the priority of the camera needs to be considered is that a plurality of camera applications conflict when calling the camera, that is, the camera has the problem of priority use only in the using process. If the camera is not used, the camera application directly calls the camera and establishes communication connection without considering the use condition of the priority of the camera.

In the use process of the camera, if another camera application needs to establish communication connection with the camera, a first calling request needs to be sent to a camera service of the card A, namely the controller, and the first calling request is a new connection request received by the camera service of the card A and is used for requesting to call the camera.

For example, if the application currently using the camera is the "look at mirror" application, at which point the "hi" application is triggered, the display device needs to be able to eject the video call request, and a first recall request is sent by the "hi" application to the a-card camera service.

And S2, if the camera is called by the second calling request, judging whether the application corresponding to the first calling request and the application corresponding to the second calling request have the application in the high-priority application list.

The application corresponding to the second calling request is the application currently using the camera. Since the camera is being used, at this time, if there is an application corresponding to the first call request to use the camera, the priority order of the camera applications that can be connected to the camera is determined by the a-card camera service.

In this embodiment, the a-card camera service (controller) establishes a high-priority application list and a low-priority application list in advance. The high priority application list refers to a list including applications that can use a camera preferentially, and the low priority application list refers to a list including applications that use a camera secondarily. The applications in the low-priority application list should avoid the applications in the high-priority application list, that is, the requirements of using the camera by the applications in the high-priority application list are prioritized.

For example, the application in the high priority application list may be an application that implements video telephony, as "hi". The video call belongs to a service process, but when a video call request is sent to the display device, the display device is required to be capable of popping up the video call request, so that the application priority of the video call is required to be the highest, and other applications are low-priority applications. In this embodiment, the display device may be a smart television, a social television, or the like.

When the two call requests for connecting the cameras conflict, the camera service of the card A needs to judge the applications corresponding to the two call requests so as to determine the priority order in which the cameras can be used. When the priority order used by the camera is determined, the embodiment determines whether the corresponding application is located in the high-priority application list in a manner of according to the application package name carried in the request.

Fig. 9 is a flowchart illustrating a method for determining camera priority usage according to an embodiment.

Specifically, as shown in fig. 9, in the display device provided in this embodiment, the controller determines whether an application located in the high-priority application list exists in the application corresponding to the first invocation request and the application corresponding to the second invocation request according to the following steps:

and S21, obtaining the name of the new application package according to the first calling request.

And S22, acquiring the name of the current application package according to the connection relation between the application corresponding to the second calling request and the camera.

S23, judging whether the new application package name is in the high-priority application list or not, and judging whether the current application package name is in the high-priority application list or not.

When an application needing to use the camera sends a first call request, the request carries an application package name, namely a new application package name. The current application being connected with the camera, that is, the application corresponding to the second call request, also carries information of the application package name, that is, the current application package name, in the connection relationship between the current application and the camera, that is, the application corresponding to the second call request.

Therefore, when the a-card camera service determines the priority of the camera used by the application, it may determine whether the corresponding application is located in the high-priority list according to the application package name, that is, respectively determine whether the new application package name is located in the high-priority application list, and determine whether the current application package name is located in the high-priority application list.

As another optional determination method, since the a-card camera service establishes the high-priority application list and the low-priority application list at the same time, when determining the priority of the application using the camera, it may further determine, according to the application package name, whether the new application package name is located in the high-priority application list or the low-priority application list, and determine whether the current application package name is located in the high-priority application list or the low-priority application list.

S3, if one application exists in the high-priority application list, determining the application existing in the high-priority application list as the high-priority application.

And according to the judgment result of the A card camera service, if one of the current application and the new application is positioned in the high-priority application list, determining the high-priority application.

A logic diagram for use in determining camera priority in accordance with an embodiment is illustrated in fig. 10.

For example, as logic shown by a solid line (line 1) in fig. 10, if the application corresponding to the first call request is located in the high-priority application list and the application corresponding to the second call request is not located in the high-priority application list, the application corresponding to the first call request is determined as the high-priority application, and the camera is connected with the high-priority application by the a-card camera service. As logic shown by a dotted line (line 2) in fig. 10, if the application corresponding to the second call request is located in the high-priority application list and the application corresponding to the first call request is not located in the high-priority application list, the application corresponding to the second call request is determined to be the high-priority application, and at this time, a prompt notification is returned by the a-card camera service to the system that sent the first call request.

Therefore, whether the application corresponding to the first calling request and the application corresponding to the second calling request have the application located in the high-priority application list or not is judged according to the high-priority application list pre-established by the A-card camera service, so that the application which can use the camera preferentially is accurately determined, confusion when a plurality of applications want to use the camera at the same time is avoided, and the sharing use function of the camera is optimized.

And S4, generating a connection permission instruction, and sending the connection permission instruction to the camera, wherein the connection permission instruction is used for establishing a communication connection relationship between the high-priority application and the camera.

After determining the high-priority application which preferentially establishes communication connection with the camera, the A-card camera service generates a connection allowing instruction, so that the camera establishes a communication connection relation with the high-priority application according to the connection allowing instruction. Since the high-priority application may be an application corresponding to the first invocation request, and may also be an application corresponding to the second invocation request, there are two possible embodiments for this purpose.

In one possible specific implementation manner, in the display device provided in this embodiment, the controller generates the connection permission instruction according to the following steps, and sends the connection permission instruction to the camera:

s411, when the application corresponding to the first calling request is determined to be a high-priority application, generating a connection allowing instruction and a connection disconnecting instruction;

and S412, respectively sending the connection allowing instruction and the connection cutting instruction to the camera, so that the camera cuts off the communication connection relation of the application corresponding to the second calling request according to the connection cutting instruction, and establishes the communication connection relation with the application corresponding to the first calling request according to the connection allowing instruction.

In this embodiment, the logic shown by the solid line (line 1) in fig. 10 is executed, and if the high-priority application is the application corresponding to the first invocation request, the camera is required to disconnect the connection state with the application in the connection relationship, that is, the connection state with the application corresponding to the second invocation request, and reestablish the communication connection relationship with the new application. For this reason, the a-card camera service needs to generate two control commands, namely a connection permission command and a connection disconnection command. The connection allowing instruction is an instruction which can establish communication connection between the camera and the high-priority application, and the connection disconnecting instruction is an instruction which can disconnect the communication connection between the camera and the low-priority application.

The A card camera service (controller) respectively sends the connection allowing instruction and the connection cutting instruction to the camera, the camera can cut off the communication connection relation of the application corresponding to the second calling request according to the connection cutting instruction, and then the communication connection relation is established with the application corresponding to the first calling request according to the connection allowing instruction.

For example, if the application corresponding to the second call request is located in the low-priority application list and the application corresponding to the first call request (hi, for example) is located in the high-priority application list, the a-card camera service obtains permission for new application connection of the currently connected camera, and executes a cut-off instruction to kick off the application corresponding to the second call request, that is, kick off the application currently using the camera, and permit "hi" connection of the camera.

In another possible specific implementation manner, in the display device provided in this embodiment, the controller generates the connection permission instruction according to the following steps, and sends the connection permission instruction to the camera:

s421, when the application corresponding to the second calling request is determined to be the high-priority application, generating a connection allowing instruction;

and S422, sending the connection permission instruction to the camera so that the camera keeps the connection of the application corresponding to the second calling request according to the connection permission instruction.

In this embodiment, the logic shown by the dotted line (line 2) in fig. 10 is executed, and if the high-priority application is an application corresponding to the second call request, the application corresponding to the first call request is not allowed to preempt the camera, and at this time, the camera does not need to disconnect the connection state with the application in the connection relationship, and continues to maintain the connection state.

For this purpose, the a card camera service sends a connection permission instruction to the camera, so that the camera continues to maintain communication connection with the current application. At this time, the application corresponding to the first call request cannot be in communication connection with the camera, and therefore, the a-card camera service needs to return prompt information to the system sending the first call request to notify the user that the new application cannot be in communication connection with the camera.

That is to say, if the application corresponding to the second call request is located in the high-priority application list and the application corresponding to the first call request is located in the low-priority application list, the camera service of the card a does not allow the application corresponding to the first call request to preempt the camera, so that confusion in use of the camera can be avoided.

In the method provided in the above embodiment, when determining the priority of the application using the camera, the a-card camera service (controller) determines that one of the applications located in the high-priority application list is a high-priority application by determining which of the application corresponding to the first invocation request and the application corresponding to the second invocation request is located in the high-priority application list. In actual application, there may be two situations that the application corresponding to the first invocation request and the application corresponding to the second invocation request are both located in the high-priority application list, or that the application corresponding to the first invocation request and the application corresponding to the second invocation request are not both located in the high-priority application list.

Another logic diagram for use in determining camera priority in accordance with an embodiment is illustrated in fig. 11.

In the first case, the a-card camera service determines that the application corresponding to the first call request and the application corresponding to the second call request are both in the high-priority application list, which indicates that both the applications are high-priority applications, and at this time, the controller needs to execute a new control method to avoid confusion in use of the camera.

Specifically, as logic shown in a route (1) in fig. 11, the present embodiment provides the display device, wherein the controller is further configured to perform the steps of: s601, if the application corresponding to the first calling request and the application corresponding to the second calling request are both located in the high-priority application list, generating a new connection instruction, and sending the new connection instruction to the camera, so that the camera establishes a communication connection relation with the application corresponding to the first calling request according to the new connection instruction.

In this embodiment, when the application corresponding to the second invocation request is in the high-priority application list, and the application corresponding to the first invocation request is also in the high-priority application list, then this embodiment may control the application corresponding to the subsequent request to use the camera according to the request sequence, that is, the a card camera service directly executes the cut-off program for the application corresponding to the second invocation request, and allows the application corresponding to the subsequent request, that is, the application corresponding to the first invocation request, to connect with the camera to perform the connection.

In this case, as an alternative embodiment, as shown in the logic of the route (2) in fig. 11, the present embodiment provides the display device, wherein the controller is further configured to perform the following steps:

and S701, if the application corresponding to the first calling request and the application corresponding to the second calling request are both located in the high-priority application list, generating a connection selection prompt, wherein the connection selection prompt is used for prompting a user to select one of the application corresponding to the first calling request and the application corresponding to the second calling request as a target connection application.

S702, receiving a selection confirming instruction generated when the target connection application is selected, generating a connection instruction according to the selection confirming instruction, and sending the connection instruction to the camera so that the camera establishes a communication connection relation with the target connection application according to the connection instruction.

In this embodiment, when the application corresponding to the second invocation request is in the high-priority application list, and the application corresponding to the first invocation request is also in the high-priority application list, then, this embodiment may also prompt the user to make a selection in a manner of displaying a prompt message, and the user may select a target connection application according to the own requirements to establish a communication connection with the camera.

For example, if the target connection application selected by the user is an application corresponding to the second invocation request, the switching procedure may not be executed at this time; and if the target connection application selected by the user is the application corresponding to the first calling request, executing the switching program. And after the user selects the target connection application, sending a confirmation selection instruction to the A-card camera service, generating a connection instruction by the A-card camera service according to the confirmation selection instruction, and sending the connection instruction to the camera.

And if the target connection application is the application corresponding to the first calling request, the A-card camera service directly executes a cut-off program on the application corresponding to the second calling request according to the connection instruction, and allows the application corresponding to the first calling request to be in communication connection with the camera. And if the target connection application is the application corresponding to the second calling request, continuing to maintain the communication connection between the application corresponding to the second calling request and the camera according to the connection instruction.

In this case, the application corresponding to the first invocation request and the application corresponding to the second invocation request are both located in the high-priority application list, and according to the two implementation manners provided above, the use priority of the camera can be controlled, so that the use of the camera is prevented from being confused.

In the second case, the a-card camera service (controller) determines that the application corresponding to the first call request and the application corresponding to the second call request are not both located in the high-priority application list, which indicates that both applications are low-priority applications, and at this time, the controller needs to execute a new control method to avoid confusion in use of the camera. Specifically, the present embodiment provides a display device, wherein the controller is further configured to perform the following steps:

s801, if the applications corresponding to the first calling request and the applications corresponding to the second calling request do not exist in the applications in the high-priority application list, determining a priority connection application capable of being in communication connection with the camera according to the application process level.

And S802, generating a connection instruction, and sending the connection instruction to the camera so that the camera establishes a communication connection relation with the priority connection application according to the connection instruction.

In this embodiment, logic shown by a two-dot chain line (line 3) in fig. 10 is executed, and when the application corresponding to the second call request is not in the high-priority application list, and the application corresponding to the first call request is also not in the high-priority application list, then, in this embodiment, an Android native priority policy is used to establish a communication connection between the application and the camera.

The Android native priority strategy is to decide who uses the camera according to the application process level when the use of the camera conflicts. Currently, Android divides processes into a foreground process, a visible process, a service process, a background process and a null process. When the memory resources are in shortage, the system determines which applications are killed to recycle the memory according to the process level, so that the applications using the camera are killed. That is, applications that are less vulnerable to killing have a higher priority for using the camera.

Foreground processes are the most important and are the last to be destroyed. Foreground processes are processes currently being displayed on the screen and some system processes, i.e. processes interacting with the user. For example, if a user is watching a video with a focused look, using this process on a television would be the foreground process.

Visible processes refer to processes in which portions of a program interface are visible to a user, but not interacting with the user in the foreground. For example, if a dialog box pops up on an interface (the dialog box is a new Activity), the original interface behind the dialog box is visible, but there is no interaction with the user, and the original interface is the visible process.

The service process is a process started by the startService () method, but does not belong to the foreground process and the visible process. For example, playing music in the background or downloading in the background is a service process.

Background processes refer to processes that are not currently visible to the user. For example, a user is watching a video using a closed look, but clicking on the home page key causes the closed look interface to disappear, at which time it transitions to a background process. Background processes may be reclaimed when memory is not sufficient.

Empty processes mean that nothing is running inside these processes. The sole purpose of retaining such a process is to act as a cache to shorten the startup time required for the application to run the component in it next time.

The recovery sequence of the above five application processes is from first to last: a null process, a background process, a service process, a visible process, a foreground process. That is, the application process level is from high to low, namely foreground process, visible process, service process, background process and null process.

According to the application process level, the priority connection application which can be preferentially in communication connection with the camera in the low-priority application can be determined. The A card camera service immediately generates a connection instruction, and if the preferential connection application is the application corresponding to the first calling request, the camera and the application corresponding to the first calling request establish communication connection; and if the priority connection application is the application corresponding to the second calling request, establishing communication connection between the camera and the application corresponding to the second calling request.

In this case, the application corresponding to the first invocation request and the application corresponding to the second invocation request are both located in the low-priority application list, and in order to ensure that the camera is successfully invoked, the method provided in this embodiment determines the application that can preferentially perform communication connection with the camera according to the mode of the application process level, thereby avoiding confusion in use of the camera.

As can be seen from the foregoing technical solutions, in the display device provided in the embodiments of the present application, a configured controller receives a first call request for calling a camera; when the camera is called by the second calling request, judging whether applications located in a high-priority application list exist in the applications corresponding to the first calling request and the applications corresponding to the second calling request, and determining the applications existing in the high-priority application list as high-priority applications; and generating a connection permission instruction, and enabling the camera to establish a communication connection relation with the high-priority application according to the connection permission instruction. Therefore, according to the display equipment provided by the application, when the camera is used and conflicts, the application which can be preferentially connected with the camera in a communication mode is selected through the camera using priority, and the connection relation between the camera and the application is established.
