ABSTRACT:
An image encoding device. The image encoding device divides the image into blocks, analyzes each block, truncates the block and determines an order using approximate points, quantizes the image data along the order determined in the truncation step, an encodes the data. Processing images with parameters along a determined order permits high quality encoded images within a limited amount of data.
