Abstract
An image data compression apparatus and image data communication system is disclosed for compressing color image data in relatively simple software process, and compressing a still or moving picture of a color image to be transmitted and/or received thereby. The image data compression apparatus generates image data having pixel data, each of which is constituted by a luminance signal and color difference signals, and generates n.times.m block data. Block components constituted by a plurality of luminance signals, color difference signals, and an n.times.m bit map representing a distribution of luminance signal components, all of which represent the generated blocks, are generated to compress the data.
