Abstract
A position of a predetermined object or design is sequentially detected from images. Then, an amount of movement of the predetermined object or design is calculated on the basis of: a position, in a first image, of the predetermined object or design detected from the first image; and a position, in a second image, of the predetermined object or design detected from the second image acquired before the first image. Then, when the amount of movement is less than a first threshold, the position, in the first image, of the predetermined object or design detected from the first image is corrected to a position internally dividing, in a predetermined ratio, line segments connecting: the position, in the first image, of the predetermined object or design detected from the first image; to the position, in the second image, of the predetermined object or design detected from the second image.
