chrominance primaryとは 意味・読み方・使い方

Also, the matrix coefficient of a second matrix circuit 46 for performing conversion from three primary color signals to the luminance and color difference signals is changed as well, and in linkage with the switching operation, the chrominance signals of a long wavelength side are suppressed and the ratio of the chrominance signals on a short wavelength side is increased.例文帳に追加

また３原色信号から輝度及び色差信号に変換する第２マトリクス回路４６のマトリクス係数も変更して、上記切替操作に連動して、長波長側の色信号を抑圧し、短波長側の色信号の比率を大きくする。 - 特許庁

In an image-processing device which holds its own density property as a reference density property beforehand and performs color conversion based on the reference density property, a color chart based on a prescribed CMYK density signal is outputted to a recording medium (S118), and a chrominance signal of a primary color scale part is obtained from a colorimetric value of the color chart (S119, S120).例文帳に追加

自身の濃度特性を基準濃度特性として予め保持し、該基準濃度特性に基づいて色変換を行う画像処理装置において、所定のCMYK濃度信号に基づくカラーチャートを記録媒体上に出力し(S118)、該カラーチャートの測色値から一次色スケール部の色信号を得る(S119,S120)。 - 特許庁
