In this embodiment, the mobile terminal includes at least a camera and a viewfinder display. The camera is used for collecting images, and the view finding display screen is used for displaying a view finding interface and the like.

It should be noted that the shooting method according to the embodiment of the present application is not limited to the steps and the sequence in the flowchart shown in fig. 1. Steps in the illustrated flowcharts may be added, removed, or changed in order according to various needs.

As shown in fig. 1, the photographing method includes the steps of:

step 101, displaying a framing picture in a framing display screen of the mobile terminal in an initial state.

It can be understood that the scene content within the focusing range of the camera of the mobile terminal is displayed in the framing picture. After the camera of the mobile terminal is started, the view-finding picture can be displayed in real time in the view-finding display screen, as shown in fig. 2, a real-time picture captured by the camera in a focusing range of the camera at a first time T1 is displayed in the view-finding display screen, so that a photographer can view the real-time picture on the mobile terminal.

In this embodiment, the viewfinder display of the mobile terminal displays the viewfinder screen in a full-screen manner in an initial state. It is understood that in other embodiments, the viewfinder display of the mobile terminal may not display the viewfinder in a full-screen manner in the initial state, for example, the viewfinder is displayed at a certain display screen ratio (e.g., 75%).

Step 102, when the selection operation is detected on the view finding picture, determining a target area selected by the selection operation.

It is understood that the selection operation may be a touch operation input by a touch object (e.g., a finger, a stylus pen, etc.) on the viewfinder display of the mobile terminal, or an operation input by a peripheral (e.g., a mouse, etc.) on the viewfinder display.

In one embodiment, the selection operation is to input an operation point in the viewing interface, for example, an operation point generated by clicking and touching the viewing interface or clicking the viewing interface with a mouse.

In one embodiment, the determining the target area selected by the selecting operation comprises:

taking an area surrounded by a circle with the operating point as the center and a first preset value as the radius as the target area; or

Taking the operation point as a center, and taking a region surrounded by a square with a second preset value as a side length as the target region, wherein four sides of the square are respectively parallel to each edge of the framing display screen; or

And taking the operation point as a center, a region surrounded by a rectangle with a third preset value as a length and a fourth preset value as a width as the target region, wherein four sides of the rectangle are respectively parallel to each edge of the view finding display screen.

In another embodiment, the selection operation is a sliding track input in the viewing interface, for example, a sliding track generated by sliding and touching the viewing interface or clicking and sliding in the viewing interface with a mouse.

In the another embodiment, the determining the target area selected by the selecting operation includes:

determining a starting point and an end point of the sliding track;

taking an area surrounded by a circle with the diameter of the connecting line of the starting point and the end point of the sliding track as the target area; or

Taking an area surrounded by a square taking a connecting line of a starting point and an end point of the sliding track as a diagonal line as the target area, wherein four sides of the square are respectively parallel to each edge of the framing display screen; or

And taking an area surrounded by a rectangle taking a connecting line of a starting point and an end point of the sliding track as a diagonal line as the target area, wherein four sides of the rectangle are respectively parallel to each edge of the viewfinder display screen.

In one embodiment, as shown in fig. 5, the first display sub-region R1 and the second display sub-region R2 are arranged in the display region of the viewfinder display in a longitudinally juxtaposed manner. It can be understood that such a split-screen display manner may correspond to a situation where the viewfinder display of the mobile terminal is in a vertical position.

Alternatively, in another embodiment, as shown in fig. 6, the first display sub-region R1 and the second display sub-region R2 are arranged in the display region of the viewfinder display screen in a laterally juxtaposed manner. It can be understood that such a split-screen display manner may correspond to a situation where the viewfinder display of the mobile terminal is placed horizontally.

In the present embodiment, the step of displaying the finder screen in real time on the first display sub-area R1 includes:
