Abstract

This paper outlines the compression and transmission system developed for high- quality color image data for prepress. This system has resulted in highly-efficient compression of color image data by using DCT(Discrete Cosine Transform) - SQ(Scalar Quantization) coding scheme adopted as the basic algorithm of the international standard for color and still picture coding in ISO. This system allows selection of a compression ratio in the range of 1/2 - 1 /50. As a result of evaluations a quality image picture for printing is obtained at a data compression ratio ranging from 1/5 - 1/10. By using the newly-developed high-speed CODEC LSIs, this system has enabled real-time data transmission to 64Kbps digital lines.
