<P>PROBLEM TO BE SOLVED: To provide an image processing device and an image processing method capable of compressing both a multivalued image and a small-valued image with sufficient compressibility. <P>SOLUTION: The image processing device comprises a coding part 204 which performs coding. When coding of the multivalued image is designated with a coding designation signal, the coding part 204 codes the multivalued image by a prediction error system using a prediction error value calculated by a prediction error generation processing part 301. When coding of the small-valued image is designated with the coding designation signal on the other hand, the coding part 204 codes the small-valued image by a coding system different from the prediction error system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
