Claim 11:
12. The method according to claim 10, wherein that the terminal determines that the picture range of motion between the first preview picture and the first reference frame picture exceeds the specified threshold comprises:
identifying, by the terminal, the first object in the first preview picture, and segmenting, by the terminal, the first object from the first preview picture;
identifying, by the terminal, the first object in the first reference frame picture, and segmenting, by the terminal, the first object from the first reference frame picture to obtain a second reference frame picture;
encoding, by the terminal, the first preview picture with the first object being segmented into a first target feature map;
encoding, by the terminal, the second reference frame picture into a first reference feature map; and
calculating, by the terminal, a similarity between the first target feature map and the first reference feature map, and when the similarity between the first target feature map and the first reference feature map is less than a specified similarity value, determining, by the terminal, that the picture range of motion between the first preview picture and the first reference frame picture exceeds the specified threshold.
