ABSTRACT:
The image data is divided into groups of a predetermined fixed length, and the divided groups are simultaneously compared to predetermined patters for the entropy encoding to render a display image in the video memory unit. Because of the above processing, the encoding process is rapidly performed, and the processing speed is lower that that of prior art image processing techniques that do not involve data compression. Thus, the above described process is comparable in image rendering to prior art techniques that do not involve encoding and decoding. Because of the encoding compression, the video memory is efficiently utilized, and the video memory capacity is reduced.
