标准范围

本文件规定了根据CIEDE2000公式计算色差的方法。本文档适用于CIELAB L*的输入值，？一个*，？b*根据ISO/CIE 11664-4计算的坐标。它可用于指定被感知为属于反射或透射物体的两个颜色刺激之间的色差。这包括显示，如果它们用于模拟反射或透射物体，并且如果表示刺激的三刺激值被适当地归一化。本文件不适用于被感知为属于看起来作为主要光源发射光或看起来镜面反射这种光的区域的颜色刺激。

This document specifies the method of calculating colour differences according to the CIEDE2000 formula.This document is applicable to input values of CIELAB L*, a*, b* coordinates calculated according to ISO/CIE 11664-4. It can be used for the specification of the colour difference between two colour stimuli perceived as belonging to reflecting or transmitting objects. This includes displays if they are being used to simulate reflecting or transmitting objects and if the tristimulus values representing the stimuli are appropriately normalized.This document does not apply to colour stimuli perceived as belonging to areas that appear to be emitting light as primary light sources or that appear to be specularly reflecting such light.
