ABSTRACT:
A method and apparatus for coding an image for reducing the amount of bit generation. Those are realized by eliminating a perceptual error from a predict error, which is generated in performing a differential pulse coded modulation (DPCM) procedure with respect to a movement between moving pictures, by using a look up table (LUT) defined for human perceptual color tolerance in the YUV chromatic domain.
