• registering said data for retrieval even for unprocessed images in said database in the order corresponding to that of arrangement of frames of said film;
• reading, upon reprocessing, from said film a plurality of images including an image to be reprocessed;
• calculating data for retrieval for said plurality of images thus input;
• and
• retrieving said image processing information for said image to be reprocessed from said database using said data for retrieval for said image to be reprocessed and for an image in at least one of frames adjacent to said image to be reprocessed on said film.
