Abstract
Provided is a method for reducing data size of images containing mutually similar information. The present method includes the steps of: generating a synthesized image corresponding to a target image based on a first reference image and a second reference image; generating a mask image indicating a potential error of the synthesized image with respect to the target image from the first reference image and the second reference image; generating a residual image in accordance with a difference between the target image and the synthesized image; generating a converted image corresponding to the target image by assigning, based on the mask image, a region where the potential error is relatively large, information on a corresponding region of the residual image; and outputting the first reference image, the second reference image and the converted image as information representing the target image, the first reference image and the second reference image.
