Title:
【発明の名称】カラー像再生のためのカラー成分信号処理方法
Document Type and Number:
Japanese Patent JP2575560
Kind Code:
B2
Abstract:
Automatic processing of color signals to print an accurate reproduction of an original color image. The RGB scan signals are processed to use the full dynamic range of the system and to adjust the values such that the gray scale lines of the color components pass through the white points. The additive color signals are converted to subtractive color signals that are adjusted so that the gray scale lines pass through the black points to produce auto-matically an accurate reproduction with a proper neutral gray scale. The processing is arranged to make the adjustments and corrections as fast as possible
