ABSTRACT:
A target code length is designated at a code length designation unit, and the entire input image data is encoded by a continuous gradation region encoding unit to obtain the target code length. On the other hand, a region segmentation unit segments the input image data into regions, a limited color region encoding unit encodes limited color regions of the segmented regions, and the continuous gradation region encoding unit encodes continuous gradation regions, so as to obtain the target code length. Either the codes obtained when the entire input image data is encoded or the codes obtained when the image data is encoded by the limited color region encoding unit and continuous gradation region encoding unit in units of regions are output on the basis of the coding unit of the codes of the entire input image data, and the coding unit of the codes of the continuous gradation region.
