Abstract
A reduced image is enlarged, difference data representing the difference between the enlarged image and an original image is obtained, and the difference data is compressed. Image data is restored by enlarging the reduced image, and expanding the difference data. When compression cannot be performed to a data size equal to or smaller than a predetermined data size, compressed difference data is not stored.
