<p>PROBLEM TO BE SOLVED: To solve the problem that a detailed part cannot be reproduced corresponding to a compression system when small characters or the like exist in a monochromatic part since a compression method suited to a color image is applied to a monochromatic image as well when the color image and the monochromatic image are mixed in an area (tile) corresponding to a packet. SOLUTION: Suitable compressing processing is applied to each of the color image and the monochromatic image included in one tile, the color image is stored in a first data part 920 of one packet 900, and the monochromatic image is stored in a second data part 930. In addition, the attribute information of these data is stored in a tag part 910.</p> |
