RGU color system

用法例句

By the color patches of medium lightness and chroma of Munsell color system,experiments were made with 34 pairs for lightness and 25 pairs for chroma altering of 5R,5Y,5G,and 5B separately,and then got a serial of new weight functions.

为了对CIEDE2000色差公式计算中等色差时的权重函数SL,SC进行修正,使计算结果与人眼的视觉感觉相一致,选用了孟塞尔(Munsell)颜色系统中的中等明度和中等彩度色块,在5R、5Y、5G、5B 4个主色调的颜色区域分别改变明度和彩度进行计算,改变彩度时共有34对样品,改变明度时共有25对样品,得到新的修正系数。

Applying the principle of linear transformation between color systems,correcting measure values relatively to measure reference,the mutual comparison between measure values is improved.

对在不同的测量仪器上测量同一颜色样品，测量结果不同的问题，利用颜色系统之间的线性变换原理及相对测量基准对测量结果进行修正，以提高测量结果之间的相互比对性。

In this experiment, CIE 1976 L*a*b*,CMC and CIEDE2000 color difference formulae are checked and compared making use of thecharacteristic of Munsell color system, which its samples nearby are of equal perceived color differenceand the Munsell hue, chroma and value can b.

利用Munsell颜色系统在视觉上为等色差系统以及色调、彩度和明度可以单独改变的特性,用CIE1976L*a*b*色差公式、CMC色差公式和CIEDE2000色差公式分别计算改变色调、彩度和明度产生的色差,从而检验各色差公式的均匀性。
