PROBLEM TO BE SOLVED: To correctly discriminate an image that has been ordered in the past. SOLUTION: An image data file relating to an image that has been ordered in the past is stored in an archive section. An image relating to an image data file read by a media drive and the image relating to the image data file stored in the archive are compared. Thereby, among the images relating to the image data file read by the media drive, a discrimination is made whether or not the image is a reprint image similar to the image that has been ordered in the past.
