With this invention, upon scanning a print, since additional information recorded together with that print is reproduced while displaying the scanned image, a special effect that cannot normally be obtained from still images can be obtained.A print on which image information and additional information, different from the image information, are printed is scanned by a scanner (209). An additional information demultiplexer (210) demultiplexes that additional information, which is decoded by an error correction decoder (211). After that, the image and the decoded additional information (moving image or/and acoustic information) are simultaneously reproduced in combination.
