Abstract

트루칼라 이미지 방식의 그래픽 시스템에서 종래의 슈도칼라 이미지 데이타를 사용할 수 있도록 슈도칼라 이미지 데이타를 트루칼라 이미지 데이타로 변환시키는 회로에 관한 것이다.The present invention relates to a circuit for converting pseudocolor image data into truecolor image data so that conventional pseudocolor image data can be used in a truecolor image system.

이를 위하여 트루칼라 이미지 그래픽 시스템에서 비트맵 데이타를 위한 칼라확장회로를 슈도칼라 이미지 그래픽 시스템의 룩업테이블 블럭으로 대치한 개선된 확장회로를 제공한다.To this end, it provides an improved extension circuit that replaces the color extension circuit for bitmap data in the true color image graphics system with the lookup table block of the pseudo color image graphics system.
