Claim 3:
4. The method according to claim 1, wherein determining the motion vector of the first image relative to the second image comprises:
performing a transverse deformation and a vertical deformation on the first image and the second image based on preset deformation ratios to obtain a first transversely deformed image, a second transversely deformed image, a first vertically deformed image, and a second vertically deformed image;
determining a first motion distance of the first image in a horizontal direction according to a horizontal movement distance of the first transversely deformed image relative to the second transversely deformed image;
determining a second motion distance of the first image in a vertical direction according to a vertical movement distance of the first vertically deformed image relative to the second vertically deformed image; and
determining the motion vector according to the first motion distance, the second motion distance, and the preset deformation ratios.
