ABSTRACT:
An image coding method that compresses an image read through an optical system. An image separation section carries out image area decisions in tile (macro block) units to separate the image into photographic image tiles and character image tiles. A layer separation section performs layer separation pixel by pixel to separate each pixel into pixels belonging to a background and pixels belonging to a foreground. Approximation processors alleviate an increase of entropy, due to layer separation through approximation processing, and carry out JPEG-like processing on photographic images.
