Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The display screen generally plays a role in a mobile terminal such as a mobile phone or a tablet computer to display contents such as text, pictures, icons or videos. With the development of touch technologies, more and more display screens arranged on mobile terminals are touch display screens, and when a user is detected to perform touch operations such as dragging, clicking, double clicking, sliding and the like on the touch display screen under the condition of arranging the touch display screens, the touch operation of the user can be responded.

With the increasing requirements of users on the definition and the fineness of displayed contents, more mobile terminals adopt touch display screens with larger sizes to achieve the display effect of a full screen. However, in the process of setting a touch display screen with a large size, it is found that functional devices such as a front camera, a proximity optical sensor, and a receiver, which are arranged at the front end of the mobile terminal, affect an area that the touch display screen can extend to.

Generally, a mobile terminal includes a front panel, a rear cover, and a bezel. The front panel includes a forehead area, a middle screen area and a lower key area. Generally, the forehead area is provided with a sound outlet of a receiver and functional devices such as a front camera, the middle screen area is provided with a touch display screen, and the lower key area is provided with one to three physical keys. With the development of the technology, the lower key area is gradually cancelled, and the physical keys originally arranged in the lower key area are replaced by the virtual keys in the touch display screen.

And functional devices such as a receiver sound outlet hole and a front camera arranged in the forehead area are important for the functional support of the mobile phone and are not easy to cancel, so that the display area of the touch display screen is expanded to cover the forehead area with great difficulty. After some research, the inventor found that functional devices such as a front camera, a proximity optical sensor, and an earpiece may be disposed inside a terminal body of a mobile terminal, and then the functional devices may be configured to rotate or slide so that the camera may be moved out and retracted with respect to the terminal body, so that the camera may be exposed inside the terminal body.

However, after finding the setting position of the mobile functional device, when the mobile terminal is used, the functional device is not usually matched with the running state of the application in the mobile terminal, and in some cases, the user needs to manually control the functional device, for example, a camera cannot be automatically controlled according to the state change of the application, which results in a lot of operations required by the user and affects the user experience. Accordingly, the inventors propose a camera control method, apparatus, mobile terminal, and storage medium for controlling movement of a camera according to an application state in the present application.

The hardware environment of the mobile terminal to which the present application relates will be described first.

As shown in fig. 1, as one mode, the mobile terminal 100 shown in fig. 1 includes a terminal body 110 and a functional device 120, where the functional device extends into the terminal body 110, is hidden in the terminal body, slidably extends out of the terminal body 110, and is exposed from a top of the terminal body 110, and the functional device 120 includes but is not limited to a camera, and one camera may be used, or two or more cameras may be used. Each camera may be directed toward the front of the mobile terminal, or may be directed toward the back of the mobile terminal or in other directions. The functional device 120 may further include a light supplement device. As an example, as shown in fig. 2, a camera 121 is disposed toward the front of the mobile terminal, and a camera 121 and a light supplement device 122 are disposed toward the back of the mobile terminal, where the camera 121 and the light supplement device 122 are sequentially arranged along the sliding-out direction of the functional device. Herein, the camera 121 facing the front of the mobile terminal may be understood as a portion of the camera that captures an image facing the front of the mobile terminal. The light supplement device facing the front of the mobile terminal may be understood as a light supplement device with a transmitting portion facing the front of the mobile terminal. The same is true for the understanding that the device is disposed towards the back of the mobile terminal. It is understood that the sliding of the functional device 120 relative to the terminal body 110 can enable the functional device 120 to move out of and extend into the terminal body 110, for example, the camera 121 slides out of the terminal body 110, i.e., the camera moves out of the terminal body 110, and the camera 121 slides into the terminal body 110, i.e., the camera extends into the terminal body 110.

Alternatively, referring to fig. 3 and 4, the mobile terminal 100 includes a terminal body 110 and a slider 130, and the functional device 120 is disposed on the slider 130. In which the slider 120 can slide with respect to the terminal body 110, so that the functional device 120 is moved out of the terminal body 110 and is exposed with respect to the terminal main body 110 (as shown in fig. 3, 4 and 5), or is inserted into the terminal body 110 and is hidden inside the terminal body 110 (as shown in fig. 6 and 7). Note that, when the functional device mentioned in the following description is removed from the terminal body 110, it may be referred to that the functional device 120 is in a state shown in fig. 2, fig. 3, fig. 4, or fig. 5. And the functional device protrudes into the terminal body 110, it is possible to refer to the state shown in fig. 1, fig. 6 or fig. 7.

Of course, the form in which the functional device 120 is moved out of the terminal body 110 and is inserted into the terminal body 110 is not limited to the form shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, and fig. 7.

The camera control method and device, the mobile terminal and the storage medium provided by the embodiment of the application monitor the running application needing to call the camera in real time, and control the camera to move out of the terminal body according to the monitored change of the state of the application, so that the camera is automatically controlled, and the user experience is improved. Embodiments in the present application will be described in detail below with reference to the accompanying drawings.

In an embodiment, please refer to fig. 8, and fig. 8 is a flowchart illustrating a camera control method according to an embodiment of the present application. According to the camera control method, the running application needing to call the camera is monitored in real time, the camera is controlled to move out and retract according to the change of the monitored state of the application, the automatic control of the camera is achieved, and the user experience is improved.

In a specific embodiment, the camera control method is applied to the camera control device 200 shown in fig. 11 and a mobile terminal equipped with the camera control device 200. The following will describe a specific process of this embodiment by taking a mobile terminal as an example, and it is understood that the mobile terminal applied in this embodiment may be a smart phone, a tablet computer, a wearable electronic device, and the like, and is not limited specifically herein.

As will be described in detail with respect to the flow shown in fig. 8, the camera control method may specifically include the following steps:

step S110: and monitoring the application needing to call the camera in real time in operation.

After the camera of the mobile terminal is arranged in the terminal body, when the mobile terminal is used, the camera is moved out from the interior of the terminal body when being used every time, and after the camera is used, the camera is retracted into the terminal body.

The camera is usually used in connection with the application calling camera of the mobile terminal, so that the running applications needing to call the camera can be monitored in real time, and the movement of the camera is controlled according to the change of the running state of the applications. The application needing to call the camera can be determined according to whether the application has the call authority of the camera, namely the application with the call authority of the camera is the application needing to call the camera, and the application without the call authority of the camera is the application not needing to call the camera.

In this embodiment of the application, the application that needs to call the camera may be a system application, such as a system camera, a setting list, a system browser, system unlocking, and the like, or may also be a third-party application, such as an application camera, a live application, a social application, a third-party browser, an AR application, a payment application, other applications related to code scanning, and the like. Of course, the system application and the third-party application are only examples, and do not limit the system application and the third-party application in the embodiment of the present application.

In the embodiment of the application, the state of the application can be monitored in real time by using the process management of the system of the mobile terminal. Therefore, the monitoring result of the application state, such as whether the application is running, whether the application has the camera authority, the interface displayed by the application, the running state of the application and the like, can be acquired in real time. Of course, the monitoring results of the states applied above are merely examples, and do not constitute a limitation on the states applied in the embodiments of the present application.

Step S120: and when the situation that the state of the application is monitored to change in a first type is monitored, controlling the camera to move out of the terminal main body.

It can be understood that, when the application enters a state that the camera needs to be called, the camera needs to enter a usable state, so that the camera can be controlled to move out of the terminal main body, so that the application can complete a task to be performed by using the camera moved out of the terminal main body.

In the embodiment of the application, when the first type of change of the application state can be monitored, the situation that the application state enters the state where the camera needs to be called is determined, and therefore the camera is controlled to move out of the terminal main body. The first type of change may be that the state of the application enters a state in which a camera needs to be called.

In the embodiment of the application, the moving-out and retracting control of the camera can be realized by controlling the motor which drives the camera to move out and retract. The motor can be controlled to rotate in a first direction to drive the camera to move out of the terminal main body; the motor can be controlled to rotate in a second direction opposite to the first direction so as to drive the camera to extend into the terminal main body.

Furthermore, the motor can drive the camera to move out or extend into a designated position by controlling the rotating speed and the rotating time of the motor. It will be appreciated that the rate of rotation of the control motor determines the rate of movement of the camera in and out, and the time of rotation of the control motor determines the time of movement of the camera in and out.

In addition, the distance between the camera and the surface of the terminal main body can be detected by controlling the camera to move out of or extend into the terminal main body, for example, the distance between the camera and the top surface is detected, so that the position of the camera relative to the terminal main body is detected, whether the camera extends into or out of the terminal main body is judged, and whether the camera extends into or out of the specified position relative to the terminal main body is judged. Specifically, the distance between the camera and the surface of the terminal body may be determined according to the change of the resistance value by sliding the rheostat, or the distance between the camera and the surface of the terminal body may be detected by a distance sensor, and specifically, the manner of detecting the distance between the camera and the surface of the terminal body is not limited in the embodiment of the present application.

Step S130: and when the situation that the state of the application is monitored to be changed in a second type is monitored, controlling the camera to retract to the terminal main body.

In the embodiment of the application, when the second type of change of the application state can be monitored, the situation that the application state enters the state without calling the camera is determined, and therefore the camera is controlled to be retracted to the terminal main body. The second type of change may be that the state of the application enters a state in which the camera is not required to be called.

The camera control method provided by the embodiment of the application carries out real-time monitoring through the application which needs to call the camera in operation, when the state of the application is monitored to change in a first type, the camera is controlled to move out of the terminal main body, when the state of the application is monitored to change in a second type, the camera is controlled to retract to the terminal main body, so that the state change of the application of the camera is called as required, the camera is controlled to move out and retract, the use requirements of users are met, and the user experience is improved.

In an embodiment, please refer to fig. 9, and fig. 9 is a flowchart illustrating a camera control method according to an embodiment of the present application. As will be described in detail with respect to the flow shown in fig. 9, the camera control method may specifically include the following steps:

step S210: and monitoring the application needing to call the camera in real time in operation.

Step S220: and when the situation that the state of the application is changed in a first type is monitored, whether the camera is moved out of the terminal main body or not is detected.

In the embodiment of the application, when the first type of change of the application state is monitored, the position of the camera can be detected, and whether the camera moves out of the terminal body or not is specifically detected, so that whether the camera needs to be controlled to move out of the terminal body or not is determined.

It can be understood that when the application needs to call the camera, the camera needs to be moved out of the terminal main body, and if the camera is already outside the terminal main body before, the camera does not need to be controlled to be moved out of the terminal main body, and only the state that the camera is moved out of the terminal main body needs to be kept, so that the application can continue to use the camera to perform tasks. And if the camera is not outside the terminal main body before, the camera needs to be controlled to move out of the terminal main body so as to enable the camera to enter a usable state.

In the embodiment of the application, whether the camera moves out of the terminal body or not can be detected by detecting the position of the camera relative to the terminal body. Similarly, the position of the camera relative to the terminal body may also be determined by the sliding rheostat according to the change of the resistance value, and the specific way of detecting the position of the camera relative to the terminal body is not limited in the embodiment of the present application.

Step S230: and if the terminal main body is not moved out, controlling the camera to move out of the terminal main body.

In step S220, if it is detected that the camera is not moved out of the terminal body, the camera is not in a usable state, and the application cannot use the camera yet, so that it is necessary to control the camera to move out of the terminal body, so that the application performs a required task using the camera.

Step S240: and when the state of the application is monitored to be changed in a second type, detecting whether the camera is moved out of the terminal main body.

In the embodiment of the application, when the two types of changes of the application state are monitored, the position of the camera can be detected, and whether the camera withdraws the terminal main body or not is specifically detected, so that whether the camera is required to be controlled to withdraw the terminal main body or not is determined.

It can be understood that when the application does not need to call the camera, the camera needs to be retracted to the outside of the terminal main body so as to protect the camera and not influence the beauty of the mobile terminal, and if the camera is already positioned outside the terminal main body before, the camera needs to be controlled to be retracted to the terminal main body. And if the camera is not positioned outside the terminal main body before, the camera does not need to be controlled to be withdrawn to the terminal main body, and only the current state of the camera needs to be kept.

Step S250: and if the terminal main body is moved out, controlling the camera to be retracted to the terminal main body.

In step S220, if it is detected that the camera moves out of the terminal body, the camera is not retracted into the terminal body, and therefore the camera needs to be controlled to be retracted into the terminal body, so that the camera is located at a position in the terminal body, and the camera is protected, which does not affect the visual experience of the user on the mobile terminal.

In this embodiment of the application, as a manner, if the terminal body is moved out, controlling the camera to be retracted to the terminal body may include:

if the terminal body is moved out, whether the first type of change occurs in the applied state is monitored within the preset time length, if yes, the camera is controlled to keep the extending state, and if not, the camera is controlled to be retracted to the terminal body.

It can be understood that the second type of change occurs in the above application, and when the camera moves out of the terminal main body, the camera can be controlled to be retracted to the terminal main body after a certain time, so that when the camera needs to be called in a short time, the camera moving out of the terminal main body can be directly utilized for use. Specifically, whether the camera needs to be called in a short time is judged by monitoring whether the state of the application changes in the first type within a preset time length. If the first type change occurs, the camera is controlled to be in an extending state so that the application can use the camera to perform required tasks, and if the first type change does not occur, the camera is controlled not to be called within a short time so that the camera is controlled to be retracted to the terminal body.

Therefore, when the camera needs to be called in a short time, the camera moved out of the terminal body can be directly used, the moving times of the camera moving out and retracting can be reduced, user experience is improved, and the influence on the service life of the camera is reduced.

According to the camera control method provided by the embodiment of the application, when the situation that the application needing to call the camera in operation changes in a first type is monitored, whether the camera moves out of the terminal main body or not is detected, when the camera does not move out of the terminal main body, the camera is controlled to move out of the terminal main body so as to use the camera, when the application changes in a second type, whether the camera moves out of the terminal main body or not is also detected, and when the camera moves out of the terminal main body, the camera is controlled to retract the terminal main body so as to protect the camera. Therefore, the state of the camera relative to the terminal main body is automatically controlled according to the change of the state of the camera required to be called, the user is not required to operate the camera, the user experience is improved, and the camera is protected.

In an embodiment, referring to fig. 10, fig. 10 is a schematic flowchart illustrating a camera control method according to an embodiment of the present disclosure. As will be described in detail with respect to the flow shown in fig. 10, the camera control method may specifically include the following steps:

step S310: and calling the application of the camera to perform real-time monitoring during running.

Step S320: and when the situation that the state of the application is monitored to change in a first type is monitored, controlling the camera to move out of the terminal main body.

In an embodiment of the present application, the first preset type of variation may include: the application enters an interface needing to call the camera; or the application is changed from background operation to foreground operation, and the current interface is the interface needing to call the camera.

It can be understood that when the application enters the interface where the camera needs to be called, it indicates that the application needs to call the camera, that is, the camera needs to be moved out of the terminal body, so that the camera is controlled to move out of the terminal body. When the application is changed from background operation to foreground operation and the current interface is the interface needing to call the camera, the application needing to call the camera also needs to call the camera, and therefore the camera is controlled to move out of the terminal main body, and the application can use the camera to perform needed tasks conveniently.

In the embodiment of the application, the interface to be called the camera may be a face authentication interface, a face unlocking interface, a scanning interface, a photographing interface, a video recording interface, a video call interface, a live broadcast interface, an AR interface, a face identity input interface or a picture-text conversion interface.

Further, when the application enters a face identity authentication interface during payment, the camera is controlled to move out of the terminal body so as to collect a face image for identity authentication, and therefore payment is completed. Fig. 11 is an interface diagram of an application entering a face authentication interface where a face is to be obtained, when the application enters the interface, the camera is controlled to move out of the terminal body, and the face authentication interface diagram after the camera moves out of the terminal body is shown in fig. 12. Of course, the above interface diagram is only an example, and does not represent a limitation on the face authentication interface in the present application.

When a face unlocking interface of the system or a third-party application is entered, the camera is also controlled to move out of the terminal body so as to collect a face image for identity authentication, so that a screen or an application program and the like can be unlocked.

When an application enters a scanning interface, for example, a bicycle application, a browser, a payment application, a chat application and the like, which can be scanned, enter an interface for scanning a bar code, the camera needs to be controlled to move out of the terminal body so as to collect the bar code and identify information of the bar code. Of course, the specific interface of the scanning interface is not limited in the embodiment of the present application, and may be other interfaces, such as a scanned document. Fig. 13 is an interface diagram of an application entering a barcode scanning interface, when the application enters the interface, the camera is controlled to move out of the terminal body, and the interface diagram of the barcode scanning after the camera moves out of the terminal body is shown in fig. 14. Of course, the above interface diagrams are merely examples and do not represent a limitation of the scanning interface in the present application.

When the application enters a photographing interface, a video recording interface and the like, such as a system camera or a third-party application camera and the like, the camera also needs to be controlled to move out of the terminal body, so that the application can utilize the camera to shoot images of a target scene for storage, recording and the like. Fig. 15 is an interface diagram of a photographing interface of an application, when the application enters the interface, the camera is controlled to move out of the terminal body, and the interface diagram of the photographing interface after the camera moves out of the terminal body is shown in fig. 16. Of course, the above interface diagrams are merely examples and do not represent limitations of the photographing interface in the present application.

When the application enters a video call interface, for example, a social application enters a video chat interface, the camera needs to be controlled to move out of the terminal body, so that the application can acquire images of the user and transmit the images to other terminals, and the purpose of video call is achieved. Fig. 17 is an interface diagram of a video chat interface, and when an application enters the interface, the camera is controlled to move out of the terminal body, and the interface diagram of the video chat interface after the camera moves out of the terminal body is shown in fig. 18. Of course, the above interface diagram is merely an example, and does not represent a limitation of the video chat interface in the present application.

Similarly, when the application enters a live broadcast interface, for example, a third-party live broadcast application enters the live broadcast interface, the camera is also controlled to move out of the terminal body so as to collect images of scenes needing live broadcast for transmission, and the purpose of live broadcast is realized.

When the application enters an AR (Augmented Reality) interface, for example, an AR game application performs an AR interface, the camera is also controlled to move out of the terminal body so as to collect images of a real scene and fuse the images with a virtual scene, and the purpose of Augmented Reality application is achieved.

When entering a face input interface in a third-party application or a system application, the camera is also controlled to move out of the terminal main body, and a face image is collected and stored; in addition, when the application enters the image-text scanning interface, the camera is controlled to move out of the terminal body, so that the character image of the target area is collected for character conversion, and the characters in the target area are obtained.

In this embodiment of the application, the entering of the application into the interface where the camera needs to be called may include: the interface of the camera is not required to be called from the same application, and the interface of the camera is required to be called; or switching to the interface of the second application in the application, which needs to call the camera, from the interface of the first application in the application, which does not need to call the camera.

It can be understood that the camera does not need to be invoked at the same interface of the application that needs to invoke the camera. The interface needing to call the camera is entered, which means that the camera is not moved out of the terminal main body when the application does not need to call the interface of the camera, so that the camera needs to be controlled to move out when the application enters the interface needing to call the camera, so that the application can use the camera. When the interface of the first application, which does not need to call the camera, is switched to the interface of the second application, which needs to call the camera, the switching process between different applications is represented, the previous interface is the interface of the first application, and the first application does not call the camera, so that the camera is not moved out of the terminal main body, and therefore when the interface is switched to the second application and the switched interface is the interface which needs to call the camera, the camera needs to be controlled to be moved out of the terminal main body, so that the second application can use the camera to perform required tasks.

In this embodiment of the application, the application changes from background running to foreground running, and the current interface is an interface that needs to call the camera, which may include: entering an interface of the application needing to call the camera from the multi-task interface; or the interface of the application needing to call the camera is entered from the main interface.

It can be understood that the application is changed from background running to foreground running, and may enter the application through a multitasking interface, or enter the application through a main interface, and when the multitasking interface and the main interface are used, the camera is not called, that is, the camera is not moved out of the terminal main body, so that the camera needs to be controlled to be moved out of the terminal main body, so that the application uses the camera to perform a required task.

In this application embodiment, when the control camera shifts out the terminal main body, can be according to opening of leading camera or the back camera control leading camera or the back camera that the application was called, specifically can be, when the leading camera was called to the application, control leading camera was opened, when the application called the back camera, control back camera was opened.

In this embodiment of the application, after controlling the camera to move out of the terminal body, the camera control method may further include:

step S330: and when the screen extinguishing signal is detected, controlling the camera to withdraw to the terminal main body.

It can be understood that after the camera moves out of the terminal body, namely the camera is in a state of moving to the outside of the terminal body, when a screen-off signal is detected, namely a key signal of a Power key (an on-off key or a Power key) of the mobile terminal is detected, it indicates that the camera is not required to be used at present, and therefore the camera is controlled to be retracted to the terminal body so as to protect the camera.

Of course, after the screen-off signal is detected, the camera is controlled to be retracted to the terminal body for use under any condition, that is, as long as the camera moves out of the terminal body, after the screen-off signal is detected, the camera is controlled to be retracted to the terminal body.

In addition, when the interface of the camera needs to be called before the screen is lightened again, the camera can be controlled to move out of the terminal body again.

step S340: and when the signal of returning to the main screen is detected, controlling the camera to return to the terminal main body.

It can be understood that after the camera moves out of the terminal body, that is, the camera is in a state of moving out of the terminal body, after the camera detects the signal of returning to the main screen, that is, the key signal of the HOME key (key returning to the main interface) of the mobile terminal is detected, it indicates that the camera is not needed to be used in the current interface, and therefore the camera is controlled to be retracted to the terminal body, so as to protect the camera.

Of course, after detecting the signal of returning to the main screen, the camera is controlled to return to the terminal body for use in any case, that is, as long as the camera moves out of the terminal body, after detecting the signal of returning to the main screen, the camera is controlled to return to the terminal body.

In addition, when the interface of the camera needs to be called before entering through the multitask interface, the camera can be controlled to move out of the terminal body again.

Step S350: and when the situation that the state of the application is monitored to be changed in a second type is monitored, controlling the camera to retract to the terminal main body.

In an embodiment of the present application, the state of the application undergoes a second type of change, including: the application enters an interface without calling the camera from the interface needing calling the camera; ending the task of calling the camera by the application; or the application changes from foreground to background.

It can be understood that, when the application enters the interface which does not need to call the camera from the interface which needs to call the camera, it indicates that no application needs to call the camera at present, that is, the camera needs to be retracted out of the terminal body at this time, so that the camera is controlled to be retracted into the terminal body, the camera is protected, and the influence on the overall appearance of the mobile terminal is reduced.

When the task of calling the camera by the application is finished, the fact that no application needs to call the camera currently is also indicated, and therefore the camera is controlled to be retracted to the terminal body, the camera is protected, and the influence on the overall appearance of the mobile terminal is reduced.

When the application is changed from background operation to foreground operation and the current interface is the interface needing to call the camera, the camera is also called when no application exists at present, so that the camera is controlled to be retracted to the terminal body, the camera is protected, and the influence on the overall appearance of the mobile terminal is reduced.

Further, the entering of the application from the interface where the camera needs to be called into the interface where the camera does not need to be called may include: the interface of the camera is required to be called from the same application, and the interface without the camera is entered; or switching to an interface which does not need to call the camera of the second application in the application from the interface which needs to call the camera of the first application in the application.

The application can enter the interface without calling the camera from the interface needing to call the camera, and can enter the interface without calling the camera from the interface needing to call the camera when the same application runs in the foreground, or enter the interface without calling the camera from the interface needing to call the camera when different applications are switched. When the interface of the camera needs to be called, the camera is in a state of being moved out of the terminal main body, and when the interface of the camera does not need to be called is entered, the camera needs to be controlled to withdraw the terminal main body, and the interface of the camera does not need to be called is entered from the interface of the camera needing to be called.

In the embodiment of the application, when the user quits the application calling the camera by using the return key, the camera also needs to be controlled to be retracted into the terminal body so as to protect the camera.

In addition, when the camera moves out of the terminal body, when the fact that a user clicks a multi-task key is detected, the camera can be controlled not to be retracted into the terminal body, and when a subsequent user selects an interface which does not need to call the camera, the camera is controlled to be retracted into the terminal body, so that the camera is prevented from moving for many times, and the influence of the moving times of the camera on the service life of the camera is reduced.

In this application embodiment, when the camera shifts out the terminal main body, when detecting the control piece of user pull-down control center, can not control the camera and withdraw to the terminal main body in, when follow-up user selection entering need not call the interface of camera, just control the camera and withdraw to the terminal main body in to avoid the multiple movement of camera, reduce the camera and remove the too much influence to camera life-span of number of times.

In the embodiment of the application, when the camera is moved out of the terminal body, the interface of the camera needs to be called by the application and is covered by other applications (such as incoming call prompt) so that the application runs in a background, and the camera can be controlled to be retracted into the terminal body. Of course, the interface requiring the camera to be called is not covered by the split screen processing, the pop-up frame, the transparent covering layer and the like, and the state that the camera is moved out of the terminal body is maintained.

According to the camera control method provided by the embodiment of the application, the camera is determined to be moved out and retracted through monitoring the change of the interface of the camera, so that the camera is automatically controlled to be moved out and retracted according to the state change of the application, the operation of a user is reduced, the camera is protected while the user experience is improved, and the influence of the camera moving out on the whole appearance feeling of the mobile terminal is reduced.

In an embodiment, please refer to fig. 19, and fig. 19 shows a flowchart of a camera control method provided in the embodiment of the present application. As will be described in detail with respect to the flow shown in fig. 19, the camera control method may specifically include the following steps:

step S410: the method comprises the steps that a foreground of the mobile terminal runs a first application and obtains a first request of the first application, wherein the first request is used for calling the camera.

It can be understood that after the camera is arranged in the terminal body, when the camera is called, the camera needs to be in a state of being moved out of the terminal body, so that the camera can be normally used; when the camera is not called, the camera does not need to be moved out of the terminal body, and the camera needs to be retracted to the terminal body so as to protect the terminal body. When the first application runs in the foreground of the mobile terminal, the first application can send a first request for calling the camera when the camera is required to be used for carrying out related tasks, so that the camera can be moved out and opened later, and the first application can use the camera to carry out the required tasks.

Step S420: and controlling the camera to move out of the terminal body according to the first request, and starting the camera.

When a first request for calling the camera is acquired, the first request can be responded, the camera is controlled to move out of the terminal body, the camera is started, the camera enters a usable state, and therefore the first application can use the camera to perform required tasks.

Step S430: and when the first application is switched to a background, closing the camera and controlling the camera to be retracted to the terminal main body.

When the first application is switched from foreground operation to background operation, the camera is not called by the first application, so that the camera is controlled to be retracted to the terminal main body, the camera is protected, and the influence of the camera stretching out on the appearance attractiveness of the mobile terminal is reduced.

In this embodiment of the present application, the step S430 may include: and when the first application is switched to the third application, closing the camera and controlling the camera to be retracted to the terminal main body. It can be understood that, the first application is switched from the foreground to the background, and the first application is switched to the second application to cause the first application to be in the background, so that the camera is closed and controlled to be retracted to the terminal main body.

In addition, the first application is switched from the foreground to the background, or the first application is switched from the foreground to the background by responding to a request for returning to the main interface when the request is received. Of course, the scenario that the first application is switched from foreground to background is not limited in the embodiment of the present application.

In this embodiment of the application, after the first application is switched to the background operation in step S430, the method may further include: and when the first application is switched from the background to the foreground, controlling the camera to move out of the terminal main body and starting the camera.

It can be understood that, when the first application is not switched to the background, the first application is in a state of calling the camera, and when the background is switched to the foreground, the first application needs to keep the previous state, so that the camera needs to be controlled to move out of the terminal main body, and the camera is started, so that the first application uses the camera to perform required tasks.

In this embodiment of the application, the first application runs in the foreground, and calls the camera, and after the camera is controlled to move out of the terminal main body, the method may further include:

and when the first application is closed, controlling the camera to be retracted to the terminal body.

It can be understood that after the first application which is running in the foreground and calls the camera is closed, the first application does not call the camera, so that the camera is controlled to be retracted to the terminal main body, the influence of the camera stretching out on the appearance attractiveness of the mobile terminal is reduced while the camera is protected.

At above-mentioned first application operation in the proscenium to call the camera, after control camera shifts out terminal subject, can also include:

when the first application is switched to a second application, and a second request of the second application is obtained, wherein the second request is used for calling the camera; and according to the second request, keeping the state that the camera moves out of the terminal body.

It can be understood that when the first application which calls the camera is switched to the second application and the second application also calls the camera, the state that the camera is moved out of the terminal main body can be kept, so that the camera does not need to be moved out of the terminal main body to meet the requirement of the second application after the camera is controlled to be retracted when the first application is switched to the background, the moving times of the camera are reduced, and the service life of the camera is prolonged.

According to the camera control method provided by the embodiment of the application, when the first request for calling the camera of the first application running in the foreground is obtained, the camera is controlled to move out of the terminal main body, the camera is started, and when the first application is switched to the background, the camera is closed and the camera is controlled to be retracted to the terminal main body. Therefore, the camera can be moved out and retracted to be automatically controlled according to the calling condition of the application program to the camera, the use requirements of users are met, the user does not need to manually move the camera, and the user experience is improved.

In addition, the touch detection function of the touch screen 109 may be implemented by using resistive, capacitive, infrared, and surface acoustic wave types. In addition to the touch screen 109, in other variations, the input module 118 may include other input devices, such as keys. The keys may include, for example, character keys for inputting characters, and control keys for triggering control functions. Examples of such control keys include a "back to home" key, a power on/off key, and the like.

The first screen 130 is used to display information input by a user, information provided to the user, and various graphic user interfaces of the mobile terminal 100, which may be composed of graphics, text, icons, numbers, videos, and any combination thereof, and in one example, the touch screen 109 may be disposed on the display panel 111 so as to be integrated with the display panel 111.
