Referring to fig. 1, a flow diagram of some embodiments of a camera invocation method in accordance with the present disclosure is shown. As shown in fig. 1, the camera calling method includes the following steps:
In this embodiment, if the camera needs to be called, the application may send a camera call request to the execution body of the camera call method.
The execution subject may be a camera call service (e.g., the camera call service 5013 shown in fig. 5). The camera call service may be a service that processes various transactions related to calling a camera.
It should be noted that the application calling the camera may be an application running in the foreground or the background.
In this embodiment, in response to receiving a camera call request sent by a first application, the execution main body may determine whether to establish a communication connection with the first application.
In some scenarios, it may be determined whether to establish a communication connection with the first application based on a number of connections with the application.
The number of connections is the number of communication connections established between the camera call service and the application. Typically, the camera call service establishes a communication connection with the same application. As can be seen, the number of connections is also the number of applications that establish communication connections with the camera call service.
In response to determining to establish a communication connection with the first application, a communication connection is established with the first application, step 102.
In this embodiment, in response to determining that the communication connection is established with the first application, the execution main body may establish the communication connection with the first application.
The execution body already establishes a communication connection with at least one application before establishing a communication connection with the first application. It is to be appreciated that the first application can be a foreground or background running application. Similarly, the at least one application includes an application running in a foreground or a background.
And 103, sending the image frames acquired by the camera in real time to the first application and at least one application which is established with communication connection in advance.
In this embodiment, the execution body may acquire image frames acquired by a camera (e.g., the camera 5014 shown in fig. 5) in real time. After establishing a communication connection with the first application, the execution main body may send the image frames acquired by the camera in real time to the first application and at least one application that has previously established a communication connection.
In some scenarios, the execution subject may transmit the first application and the at least one application with one or more image frames captured by the camera in real time.
It can be understood that, by sending the image frames acquired by the camera in real time to the first application and the at least one application, the first application and the at least one application can call the camera at the same time.
In the related art, when a preceding application calls a camera, if a succeeding application requests to call the camera, the preceding application needs to close the camera, and the succeeding application can open the camera, so that the succeeding application calls the camera. Generally, it takes a certain time for a preceding application to turn off a camera to turn on the camera by a succeeding application. On the one hand, it may take a long time for the post-application to acquire the image frames acquired by the camera in real time. On the other hand, turning off the camera on at a high frequency may cause loss of the camera.
In this embodiment, in response to receiving a camera call request sent by a first application, the camera call service may determine whether to establish a communication connection with the first application, and further, in response to determining to establish a communication connection with the first application, the camera call service may establish a communication connection with the first application and send image frames acquired by the camera in real time to the first application and at least one application that has previously established a communication connection. Therefore, the first application and the at least one application call the camera at the same time by means of the camera call service.
In addition, according to the scheme described in this embodiment, it is avoided that the camera is turned on by a subsequent application (e.g., the first application) after the camera is turned off by a previous application (e.g., the at least one application). Therefore, on one hand, the image frames acquired by the camera in real time in a short time can be acquired in a post application mode, and on the other hand, the camera loss caused by closing and opening the camera at a high frequency can be avoided.
In some embodiments, the execution body may determine whether to establish a communication connection with the first application according to a flow shown in fig. 2. The process includes at least one of the following steps.
The maximum number of connections is the maximum number of communication connections established between the camera call service and the application. It will be appreciated that a larger maximum number of connections means a larger number of applications that can call the camera at the same time. Meanwhile, the more applications calling the camera, the higher the performance requirement on the electronic equipment. Generally, the maximum connection number may be preset according to the performance of the electronic device, so as to ensure that when a plurality of applications call the camera at the same time, other tasks running on the electronic device are not greatly affected.
In some scenarios, the execution agent may monitor the number of connections to the application in real time. The execution principal may refuse to establish a communication connection with the first application if the number of connections with the application is greater than or equal to the maximum number of connections. The execution body may determine to establish a communication connection with the first application if the number of connections to the application is less than the maximum number of connections.
By setting the maximum connection number, the maximum number of applications that call the camera to establish communication connection with the application can be limited (that is, the maximum number of applications that call the camera at the same time is limited). Therefore, the camera can be called by a plurality of applications simultaneously on the premise of combining the performance of the electronic equipment.
In some embodiments, the execution body may further perform the following steps.
Specifically, in response to receiving a camera disconnection request sent by the second application, the communication connection with the second application is disconnected.
The camera disconnect request may be a request to disconnect a camera call. If the call of the camera needs to be disconnected, the application can send a camera disconnection request to the execution main body.
It is understood that disconnecting the communication connection with the second application means disconnecting the call of the second application to the camera. Therefore, the calling of the second application to the camera can be disconnected by disconnecting the communication connection between the camera calling service and the second application. Therefore, after the second application disconnects the communication connection with the camera calling service, if other applications in communication connection with the camera calling service still exist, the second application does not influence the calling of the other applications to the camera.
In some embodiments, the executing agent may execute the camera call method according to the flow shown in fig. 3. The process includes steps 301 to 305, wherein the execution manners of steps 301, 302 and 303 are similar to the execution manners of steps 101, 102 and 103 in the embodiment shown in fig. 1, and are not described herein again.
And step 304, responding to the condition that the connection number of the camera calling service and the application is 0, and closing the camera.
The number of connections of the camera call service and the application is 0, meaning that no application calls the camera. Thus, if no application calls the camera, the camera is turned off.
And 305, responding to the condition that the number of the connection between the camera calling service and the application is greater than or equal to 1, and keeping the camera on.
The number of connections of the camera call service to the application is greater than or equal to 1, meaning that there are one or more application call cameras. Therefore, if the application calling camera exists, the camera is kept started, and therefore it is guaranteed that the application calling the camera can acquire the image frames acquired by the camera in real time.
In some embodiments, the camera invocation service is a service that handles at least one of: turning on and/or turning off the camera; establishing communication connection with an application requesting to call the camera, and/or disconnecting communication connection with an application requesting to disconnect the call of the camera; acquiring image frames acquired by a camera in real time; and sending the image frames acquired by the camera in real time to the application in communication connection.
Therefore, the calling of the application to the camera is realized by means of at least one of the camera calling service processing.
With further reference to fig. 4, as an implementation of the methods shown in the above figures, the present disclosure provides some embodiments of a camera invocation device, which correspond to the method embodiment shown in fig. 1, and which can be specifically applied to various electronic devices.

In some embodiments, the determination unit 401 is for at least one of: refusing to establish communication connection with the first application in response to the fact that the connection number of the camera calling service and the application is larger than or equal to the maximum connection number; and determining to establish communication connection with the first application in response to the fact that the connection number of the camera calling service and the application is smaller than the maximum connection number.
In some embodiments, the camera call device may further include a disconnection unit (not shown in the figure). The disconnection unit is used for: and in response to receiving a camera disconnection request sent by the second application, disconnecting the communication connection with the second application.
In some embodiments, the camera call device may further include at least one of a closing unit (not shown in the drawings) and a holding unit (not shown in the drawings). The closing unit is used for: and responding to the situation that the number of the connection between the camera calling service and the application is 0, and closing the camera. The holding unit is used for: and responding to the situation that the number of the connection between the camera calling service and the application is more than or equal to 1, and keeping the camera on.

The terminal device 501 may be installed with applications having various functions, such as a shopping application, a search application, a news application, and the like. If the camera 5014 needs to be called, the application installed in the terminal apparatus 501 may send a camera call request to the camera call service 5013.
In some scenarios, in response to receiving a camera call request sent by the first application 5011, the camera call service 5013 may determine whether to establish a communication connection with the first application, and further, in response to determining to establish a communication connection with the first application 5011, the camera call service 5013 may establish a communication connection with the first application 5011 and send image frames captured in real-time by the camera 5014 to the first application 5011 and the application 5012 that previously established the communication connection.
