ABSTRACT:
An image processing apparatus for compressing and decompressing image data. The apparatus includes: a composition circuit for composing composed data, having a predetermined bit width, from the given image data which correspond to spatially continuous pixels of an image; a compression circuit for compressing the composed data with Lempel-Ziv algorithm so as to obtain compressed data; a memory for storing the compressed data therein; and a controller for controlling the composition circuit and the compression circuit.
