Claim 10:
11. 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:
generating, by the terminal, a first mask map after segmenting the first object from the first preview picture;
generating, by the terminal, a second mask map after segmenting the first object from the first reference frame picture; and
calculating, by the terminal, an intersection over union between the first mask map and the second mask map, and when the intersection over union between the first mask map and the second mask map is less than a specified intersection over union 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.
