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 service module may send a camera call request to an execution main body (for example, the terminal device 501 shown in fig. 5) of the camera call method.
A business module may be a module included in an application to implement a certain function. In general, a plurality of service modules may be included in one application.
In this embodiment, the execution main body may receive a camera call request sent by the first service module. The camera call request comprises a priority field for representing the target call priority of the first service module.
The calling priority is the priority of the service module calling the camera.
And 102, determining whether to switch and call the service module of the camera or not by comparing the target call priorities of the first service module and the second service module which calls the camera currently.
In this embodiment, the execution main body may determine whether to switch and call the service module of the camera by comparing target call priorities of a first service module and a second service module that calls the camera currently.
It is easy to find that the second service module is a service module which calls the camera at present.
And 103, responding to the service module which determines to switch and call the camera, and switching the camera to be called by the first service module.
In this embodiment, in response to determining to switch to call the service module of the camera, the execution main body may switch the camera to be called by the first service module.
The fact that the first service module calls the camera can be easily found by switching and calling the service modules of the camera. After the switching, the second service module cannot call the camera.
In the related art, after one service module calls the camera, another service module can call the camera. Therefore, the time for calling the camera by the same service module is too long, so that other service modules cannot call the camera for a long time. Further, the flexibility of calling the camera by different service modules may be low.
In this embodiment, in the process of calling the camera by the second service module, if a camera calling request sent by the first service module is received, whether to switch and call the service module of the camera is determined by comparing the target calling priorities of the first service module and the second service module. Further, in response to determining to switch and call the service module of the camera, the camera is switched to be called by the first service module. Therefore, the camera can be prevented from being called by other service modules (for example, the first service module) after the camera is called by one service module (for example, the second service module). Therefore, the problem that the camera cannot be called by other service modules for a long time due to the fact that the same service module calls the camera for too long time can be avoided, and flexibility of calling the camera by different service modules is improved.
In some embodiments, the execution subject may also execute step 104 in the flow shown in fig. 1.
And 104, responding to the refusal of switching and calling the service module of the camera, and sending a calling failure notice to the first service module.
Therefore, when the first service module fails to apply for calling the camera, the first service module can be notified that the camera is not called by sending a calling failure notification.
It can be understood that after the first service module fails to call the camera, the second service module continues to call the camera.
In some embodiments, the execution subject may switch the camera to be called by the first service module in the following manner.
Specifically, a camera release notification is sent to the second service module, so that the second service module releases the camera, and the first service module calls the camera.
Therefore, the second service module releases the camera by sending a camera release notification to the second service module.
In some embodiments, the first service module and the second service module are from different applications.
It can be understood that the second service module calls the camera, that is, the application including the second service module calls the camera. The first service module applies for calling the camera, namely the application comprising the first service module calls the camera.
Therefore, after one application (for example, the application comprising the second service module) calls the camera, other applications (for example, the application comprising the first service module) can be prevented from calling the camera. Therefore, the problem that the camera cannot be called by other applications for a long time due to the fact that the same application calls the camera for a long time can be avoided.
In some embodiments, the executing entity may determine whether to switch and call the service module of the camera according to the flow shown in fig. 2.
As can be seen, even if the service module (e.g., the second service module) currently calling the camera does not end the call of the camera, the service module (e.g., the first service module) having the same or higher call priority may successfully call the camera.
It can be seen that if the service module (e.g., the first service module) applying for calling the camera has a lower calling priority, the camera cannot be successfully called.
In some embodiments, the service module may send a camera call request to the execution main body in the following manner.
Firstly, determining the target calling priority of a service module.
And secondly, sending a camera calling request comprising a priority field for representing the target priority.
In some scenarios, the service module may apply for a call priority from the execution subject. Further, the service module may use the call priority approved by the execution subject as a target call priority. Thus, the service module may send a camera call request to the execution body, including a priority field characterizing a target call priority.
It can be seen that, if the service module needs to call the camera, a camera call request including the priority field may be sent, so as to determine the target call priority of the service module based on the priority field subsequently.
In some embodiments, the call priority customized by the developer for the business module includes any one of a first call priority, a second call priority, and a third call priority. And the priorities of the first calling priority, the second calling priority and the third calling priority are sequentially reduced.
If the service module has the calling priority with higher priority, the probability of successfully calling the camera in a short time is higher. Accordingly, if the service module has a lower priority for calling, the probability of successfully calling the camera in a shorter time is lower.
In some embodiments, the service module may determine its target call priority according to the flow illustrated in fig. 3A.
The developer can customize the corresponding calling priority for the business module. Generally, a developer can customize the calling priority of the service module according to the importance degree of the service module calling the function realized by the camera.
In some scenarios, a developer may customize a lower priority call priority (e.g., a second call priority or a third call priority) for a business module running in the foreground. Therefore, if the importance degree of the function realized by calling the camera by the service module operated in the foreground is lower, the condition that the camera is occupied by the service module operated in the foreground for a long time can be avoided by the calling priority with lower custom priority.
In some scenarios, the developer may also customize a higher priority call priority (e.g., the first call priority) for the background running business module. Therefore, if the function realized by calling the camera by the service module running in the background is more important, the camera can be successfully called by the service module running in the background in a shorter time by customizing the calling priority with higher priority.
It should be noted that, if the application includes a plurality of service modules, the developer may customize corresponding call priorities for each service module.
Therefore, if the developer customizes the calling priority of the service module, the calling priority customized by the developer is used as the calling priority of the service module. And if the developer does not self-define the calling priority of the service module, determining the calling priority of the service module based on the calling priority preset by the system.
In some embodiments, the service module may determine its target call priority based on the call priority preset by the system according to the flow shown in fig. 3B.
The system may preset a call priority for the traffic module.
Therefore, if the developer does not self-define the calling priority of the service module, the target calling priority of the service module can be determined based on the fact that the service module runs in the foreground or the background. Moreover, the service module running in the foreground has higher target calling priority, and the service module running in the background has lower target calling priority. Therefore, the service module operated in the foreground can be ensured to successfully call the camera in a short time as far as possible.
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 general, an application installed on the terminal device 501 may include a plurality of service modules, wherein different service modules may implement different functions. In some scenarios, the first and second service modules 5011 and 5013 may be service modules included by different applications.
In some scenarios, in the process of calling the camera 5012 by the second service module 5013, if a camera calling request sent by the first service module 5011 is received, the terminal device 501 may determine whether to switch the service module calling the camera 5012 by comparing the target calling priorities of the first service module 5011 and the second service module 5013. Further, in response to determining to switch to invoke the service module of the camera 5012, the terminal device 501 may switch the camera 5012 to be invoked by the first service module 5011.
