Description

채도 조정방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도는 농도를 색상, 명도 및 채도로 변환하는 수순을 나타낸 설명도. 제 2 도는 본 발명의 채도조정방법이 적용되는 칼라 복사기의 전체구성예를 나타낸 블록도. 제 3 도는 조작판넬의 일예를 나타낸 정면도. 제 5 도는 색상, 명도 및 채도의 각 신호로 부터 화상출력장치에 있어서의 각 색채마다의 비트수를 직접 출력하는 루크업테이블 형식의 ROM을 나타낸 블록도.

Claims (2)

  1. 칼라원고를 판독하여 얻은 적, 녹 및 청의 색농도를 색상, 명도 및 채도로 변환시키고 상기 채도를 조정한후에 상기 색상 및 명도와 조합시켜 색재농도로 변환하고 이 색재 농도에 따라 칼라화상을 출력하는 것을 특징으로 하는 채도조정방법.
  2. 제 1 항에 있어서, 상기 채도를 하기식으로 표시하는 것을 특징으로 하는 채도조정방법.
    C=2.44×V×{max(DR, DG, DB)}-{min(DR, DG, DB)}
    단 C : 채도
    V : 명도
    D : 시감농도
    D=α1×DR+α2×DG+α3×DB
    α1α2α3: 계수
    DR, DG, DB: 적, 녹, 청의 농도.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
