ABSTRACT:
According to this invention, encoded data are generated by sorting pixel data in a block according to different scan start positions and different scan routes upon generating encoded data for respective blocks, and encoded data with a smallest data amount of these encoded data is outputted. To this end, a block generation unit inputs blocks each defined by 8×8 pixels from image data to be encoded. Four encoding processing units respectively sort inputted 8×8 pixels according to the information stored in scan start position information storage units and scan route information storage units. The respective encoding processing units generate encoded data based on the sorted pixel data. A selector selects and outputs encoded data with a smallest data size from those generated by the encoding processing units.
