ABSTRACT:
An image encoding method, and an apparatus therefor, enabling rapid comprehension of the outline of the entire image promptly, at the decoding of the encoded image information, and also an image encoding method, and an apparatus therefor, capable of efficient encoding adapted for the state of the image to be encoded. Image information is divided into plural block, each consisting of plural pixels, the frequency of the image in each block is analyzed, the frequency components of the image in each block are separated into plural bands, and the frequency components contained in each of said plural bands are encoded.
