In accordance with this compression conversion rule, an image compression block 140 compresses original image data and holds the compressed image data in an image memory 150 along with a type of the compression conversion rule. This type of the compression conversion rule held in the image memory 150 is extracted by a decompression conversion rule setting block 160. In accordance with this type, a decompression conversion rule is set to a decompression conversion table 170. In accordance with the decompression conversion rule set to the decompression conversion table 170, an image decompression block 180 decompresses the compressed image data held in the image memory 150.
