step S310: and receiving a shooting instruction of a user, enabling the mobile terminal to enter a shooting mode, calling a first shooting device to perform framing, and displaying a framing area in a first framing frame.
The embodiment of the present invention may be applied to a mobile terminal such as a mobile phone, where the mobile terminal includes two shooting devices, and the shooting device is a camera capable of shooting an image. A camera driver is usually installed in the mobile terminal, and displays an application interface of a camera with the mobile phone. The user calls the corresponding camera by clicking the camera application interface, the current picture is shot through the camera, and the currently shot picture is displayed in the view-finding frame of the camera.
It should be noted that, the mobile terminal receives a user shooting instruction through a human-computer interaction interface, and the human-computer interaction interface is usually a touch display screen. And the user sends an operation instruction to the mobile terminal by manually touching the display screen. For example, when the user clicks the camera of the application program in the click, the operation is that after receiving the instruction of the user, the mobile phone opens the camera application program to enter a shooting mode, and calls the camera.
It can be understood that, after the mobile terminal enters the photographing mode, the mobile terminal invokes the first photographing device, in an embodiment of the present invention, the first photographing device is a camera of the mobile terminal, a view frame corresponding to the first photographing device is correspondingly displayed in a display area of the mobile terminal, and a current view area is correspondingly displayed in the view frame.
Illustratively, parents participate in kindergarten activities, start a first camera of a mobile phone to shoot the kindergarten activities, and the current activities of the kindergarten are displayed in a first view frame after all the current activities of the kindergarten are viewed by the first camera.
Step S320: and selecting a target area based on the first view frame, wherein the target area is a closed area.
It is understood that, the user may perform a frame operation through the first view frame, for example, select a partial region on the frame, in this embodiment of the present invention, the user manually selects a target region from the first view frame. The target area may be a closed area that a user manually draws.
For example, the kindergarten parents can see the activities of a plurality of children in the first viewing frame, and if the kindergarten parents want to capture the activities of the children of their family, the children of their family can be selected in the first viewing frame to form a closed area, for example, from the head top of the children to form an area surrounding the kindergarten.
Step S330: and receiving an instruction of calling a second shooting device by the user.
After the user selects the target area, the second shooting device may be called by an instruction, and a specific implementation manner may be: and after the user selects the target area, the mobile terminal pops up a dialog box to ask the user to confirm whether the second shooting device needs to be called, and if the user clicks to confirm that the second shooting device needs to be called, the instruction of calling the second shooting device is realized.
For example, after selecting the target area, the user may click the second camera from the current shooting interface, for example, a display mark of the camera is set on the mobile phone, and when the display mark is clicked directly after selecting the target area, the instruction of the user to call the second camera is completed, as shown in fig. 4.
Step S340: and shooting the target area by adopting the second shooting device, and displaying the target area in a second view frame.
In the embodiment of the invention, after the second shooting device is called, the target area is directly shot, and the shot area is displayed through the view frame.
