Claim 6:
7. The method according to claim 5, wherein determining the second motion distance of the first image in the vertical direction according to the vertical movement distance of the first vertically deformed image relative to the second vertically deformed image comprises:
setting the first vertically deformed image and the second vertically deformed image as parallel in the vertical direction and aligned at two ends;
moving the first vertically deformed image in the vertical direction in sequence of movements, and determining, after each of the sequence of movements, two sub-images respectively corresponding to the first vertically deformed image and the second vertically deformed image in the horizontal direction, calculating second difference values between the two sub-images, and determining a total quantity of moved pixels of the first vertically deformed image after the sequence of movements;
determining a minimum second difference value among the second difference values as a second target difference value; and
determining a total quantity of moved pixels corresponding to the second target difference value as the second motion distance of the first image in the vertical direction.
