And 507, determining the folding direction of the target display screen where the target camera is located according to the movement direction.

In the embodiment of the application, the motion track of the second electronic device includes a motion direction and a motion distance, the folding parameters of the target display screen T include a folding direction and a folding angle, and when the motion direction in the motion track of the second electronic device moves from an initial position to a first direction, the target display screen T is folded towards the display surface of the display screen connected with the target display screen T; when the movement direction in the movement locus of the second electronic device is from the initial position to the second direction, the target display screen T is folded away from the display surface of the display screen connected with the target display screen T. Therefore, the folding direction of the target display screen T can be determined through the movement direction in the movement track of the second electronic device, so that the target display screen T can be folded subsequently.

The first direction may be upward movement along the initial position, and the second direction is downward movement along the initial position, or the first direction is forward movement along the initial position, and the second direction is backward movement along the initial position, or the first direction is rightward movement along the initial position, and the second direction is leftward movement along the initial position, and the specific direction may be set according to an actual situation, which is not limited in this embodiment of the application.

And step 508, determining the folding angle of the target display screen where the target camera is located according to the movement distance.

In this embodiment of the application, the movement locus of the second electronic device includes a movement distance, and the folding angle of the target display screen T may be determined according to the movement distance of the second electronic device in the first direction or the second direction.

For example, when the movement distance in the first direction is 3cm, the folding angle at which the target display screen T is folded toward the display surface of the display screen connected to the target display screen T is 30 °, the target display screen T can be folded according to the preset frequency in the folding process, for example, the target display screen T can be folded according to 10 ° per second, folding for 3 seconds is completed by 30 degrees, a correspondence table between the movement distance and the folding angle is stored in the first electronic device, after the movement distance is acquired, the folding angle corresponding to the movement distance can be searched in the correspondence table, and then the folding angle of the target display screen T is determined according to the folding angle.

In the embodiment of the application, the folding angle of the target display screen T can be determined through the movement distance in the movement track of the second electronic device, and the determination of the folding angle of the target display screen T can be used for folding the target display screen T so as to adjust the shooting range of the target camera positioned on the target display screen T.

And 509, controlling the target display screen to be folded according to the folding parameters so as to adjust the shooting range of the target camera.

This step is similar to the step 105 of the above embodiment, and is not described herein again.

In the practical use process, after the target display screen T is subjected to one folding operation, the integrity of the target object T included in the preview image acquired by the target display screen T may still not meet the requirement, and therefore the target display screen T may be folded for multiple times.

Therefore, after step 509, the method further comprises: determining an initial angle between the target display screen and a display screen connected with the target display screen; determining the difference value between the maximum folding angle of the target display screen and the initial angle as the preset angle; and under the condition that the folding angle of the target display screen reaches a preset angle and the contour integrity of the target object in the preview image collected by the target camera is smaller than a second set value, finishing shooting and generating a shooting file.

In the embodiment of the application, an initial angle between a display surface of a target display screen T and a display surface of a display screen connected to the target display screen T is determined, the display surface of the display screen connected to the target display screen T is used as a reference surface, an included angle between the display surface of the target display screen T and the reference surface is detected through a gyroscope in first electronic equipment, and the included angle is determined as the initial angle.

For example, when the display surface of the target display screen T and the display surface of the display screen connected thereto are located on the same plane, the initial angle between the target display screen T and the display screen connected thereto is 180 °.

In the embodiment of the application, when the display surface of the target display screen T is in full contact with the display surface of the display screen adjacent to the target display screen T, the target display screen T is folded, so that one side of the folded target display screen T, which is deviated from the display surface, is in full contact with one side of the display screen adjacent to the target display screen T, which is deviated from the display surface, 360 ° is folded in the folding process, and the folding angle is defined as the maximum folding angle.

In the embodiment of the application, a difference value between the maximum folding angle and the initial angle of the target display screen T is calculated, and the difference value is used as a preset angle to judge the folding process of the target display screen T, so as to judge whether the target display screen T can be continuously folded or not, and further determine whether to continuously shoot or not.

For example, when the initial angle of the target display screen T is 180 °, the maximum folding angle of the target display screen T is 360 °, and the preset angle is 360 ° -180 ° =180 °.

And controlling the target display screen T to be folded according to the folding parameters until the folding angle of the target display screen T in the folding process reaches a preset angle, at the moment, judging whether the integrity of the outline of the target object T in the preview image acquired by the target camera is smaller than a second set value or not, when the integrity of the outline of the target object T is smaller than the second set value, finishing the shooting and generating a shooting file, wherein the shooting file is stored in the first electronic equipment for a user to check.

The second setting value may be the same as or different from the first setting value, and this is not limited in this embodiment of the application.

For example, when the second setting value is 70%, the contour integrity of the target object t in the preview image captured by the target camera is 50%, and since 50% < 70%, this capturing is ended at this time.

In the embodiment of the application, when the folding angle of the target display screen T reaches the preset angle and the integrity of the contour of the target object T in the preview image is smaller than the second set value, that is, the integrity of the contour of the target object T in the preview image is lower at the moment, the shot preview image has no use value, and the shooting is finished at the moment, so that the electric quantity of a terminal can be saved, the utilization rate of shot files can be improved, and the storage space of the terminal can be saved.

It should be noted that when the integrity of the contour of the target object t in the preview image is greater than the second set value, the shooting is continued until the user actively terminates the shooting.

In the embodiment of the application, under the condition that the contour integrity of a target object in a preview image is smaller than a first set value, first electronic equipment sends prompt information to second electronic equipment, the first electronic equipment controls the folding direction of a target display screen according to the movement direction in a movement track returned by the second electronic equipment, controls the folding angle of the target display screen according to the movement distance in the movement track, and does not need a user to manually adjust the target display screen.
