IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM RECORDING PROGRAM TO ALLOW COMPUTER TO PERFORM THE METHOD

摘要

PROBLEM TO BE SOLVED: To conduct fixed length coding reflecting a partial feature of an image on coded data without incurring deterioration in a coding efficiency. SOLUTION: A block re-division processing section 103 re-divides a block into small blocks, an image conversion processing section 104 extracts an edge and a pixel mean value from image data in each small block, and a coding processing section 106 converts the image data in the block into fixed length data on the basis of the presence of the edge in each extracted small block and a conversion table 105.
