3 . The method according to claim 2 , wherein

in response to the ratio of the first image data being greater than the ratio of the second image data, a height of the target region is a height of the first image data;

in response to the ratio of the first image data being smaller than the ratio of the second image data, a width of the target region is a width of the first image data.

4 . The method according to claim 2 , wherein determining the target region in the first image data comprises:

determining key image information included in the first image data; and

determining a region including the key image information in the first image data as the target region.

5 . The method according to claim 1 , wherein before performing the first processing on the second image data subjected to the effect processing, the method further comprises:

determining a first angle according to the screen rotation angle, wherein a sum of the first angle and the screen rotation angle is 0 degrees or 360 degrees; and

transposing the second image data subjected to the effect processing according to the first angle.

6 . The method according to claim 1 , wherein before cropping the first image data to the second image data, the method further comprises:

receiving a target ratio input into the application program; and

adjusting the ratio to be used for the second image data to the target ratio.

7 . The method according to claim 6 , further comprising:

in response to the adjusted ratio to be used for the second image data not matching the ratio of the first image data, selecting, from candidate ratios of the image acquisition device, a ratio that matches the adjusted ratio to be used for the second image data as the ratio of the first image data.

8 . The method according to claim 7 , wherein after selecting, from the candidate ratios of the image acquisition device, the ratio that matches the adjusted ratio to be used for the second image data as the ratio of the first image data, the method further comprises:

restarting preview of the image acquisition device according to an adjusted ratio of the first image data, thereby entering the step of calling the image acquisition device by the application program to obtain the first image data.

9 . An electronic device, comprising: at least one processor and a memory;

the memory storing computer-executable instructions;

the at least one processor executing the computer-executable instructions stored in the memory, to cause the electronic device to perform operations comprising:

calling an image acquisition device by an application program to obtain first image data;

adjusting a ratio to be used for second image data in response to a screen rotation angle being greater than or equal to a pre-set angle threshold;
