摘 要: 介绍了CIE1976LAB色度椭圆,并在中国颜色体系的基础上,分别从色相、明度、饱和度的角度对ΔE*ab的均匀性进行了研究。结果表明,该色差公式明度的均匀性较好,色相、饱和度的均匀性较差,该公式不能够很好地反应人眼的视觉感受。 The color discrimination ellipses of CIE 1976 LAB color space were introduced.Based on Chinese Color system, the uniformity of ΔE~*_(ab) is researched. It was proved that the uniformity of value (V) was better than those of chrma(C) and hue(H), and so the color difference formula was not consistent with the perceived color difference.
