ABSTRACT:
A device and process for encoding a gradation image of an image transmission system. In order to reduce the amount of transmission data while preserving an edge component sensitive to a human's visual characteristic in a half tone image considering similarity between blocks, a block to be encoded is checked to see if it is an edge block, a block similar to an adjacent block or a flat block. By the checked result, the block is encoded to first to fourth encoding formats.
