A position of a predetermined object or a predetermined design is sequentially detected from images. Then, an amount of movement of the predetermined object or the predetermined design is calculated on the basis of: a position, in a first image, of the predetermined object or the predetermined design detected from the first image; and a position, in a second image, of the predetermined object or the predetermined 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 the predetermined design detected from the first image is corrected to the position, in the second image, of the predetermined object or the predetermined design detected from the second image. |
