The target picture may be, but is not limited to, a normal-sized and normal-sized picture that requires image processing. The thumbnail may be, but is not limited to, a picture generated according to a preset coefficient based on a normal picture.
In an embodiment, as shown in fig. 2, the step of acquiring processing information corresponding to the target picture, where the processing information includes a thumbnail and a preset coefficient includes:
step 210: acquiring a target picture;
step 220: keeping the aspect ratio of the target picture unchanged, and generating a thumbnail corresponding to the target picture according to a preset coefficient.
Specifically, the acquisition target picture may be, but is not limited to, acquired from the terminal itself, or acquired from another terminal. And under the condition of keeping the aspect ratio of the target picture unchanged, generating a thumbnail corresponding to the target picture according to a preset coefficient. The preset coefficient may be, but not limited to, set by the user, or may be automatically generated according to the size of the terminal memory. The preset coefficient is a reference value for generating a thumbnail corresponding to the target picture, the thumbnail being displayed in the operation area with a lower memory occupied than the target picture. The height and width size of the thumbnail is equal to/the preset coefficient of the height and width size of the target picture corresponding to the thumbnail. For example, as shown in fig. 3, the normal picture 31 has a height H1 and a width W1, and the thumbnail picture 32 has a height H2 and a width W2 after scaling by a preset coefficient S.
