Abstract

A method for converting digital signal of illumination, hue and color space of the signal of RGB color space, comprising the steps of: generating a plurality of hue and color space signal of predetermined linear combination to at least one space signal of illumination-color; providing a multiplexing multiple unit for receiving the hue and color space signal of predetermined linear combination, the multiplexing multiple unit includes two checking tables for storing the converting value of the hue and color space signal of predetermined linear combination which is operated by a matrix operation; linear combining the converting value from the matrix operation and the hue and color space signal of predetermined linear combination and by a first predetermined step to generate three RGB color combining signal; and by a second predetermined step to generating RGB color space signal.
