ABSTRACT:
A device for processing images includes a compressing/coding unit which encodes image data including a plurality of color components to produce fixed-length codes, a memory unit which stores therein the codes produced by the compressing/coding unit, a distribution-measurement unit which measures a distribution of the color components concurrently with the encoding of the image data performed by the compressing/coding unit, and a memory-control unit which releases a memory space assigned to part of the codes relating to colors in the memory unit if the distribution-measurement unit detects that the distribution concentrates on a particular color composition, and records data indicative of the particular color composition in the memory unit.
