本文件规定了色度学中使用的颜色匹配功能。指定了两套颜色匹配功能。-CIE 1931标准色度观察仪的颜色匹配功能。这组颜色匹配函数代表了具有正常颜色视觉的观察者的颜色匹配特性，其视野大小的角度从约1°到约4°，适用于明视适应水平的视觉。-CIE 1964标准色度观察仪的颜色匹配功能。这组颜色匹配功能代表颜色-具有正常色觉的观察者的匹配特性，其视野大小的角度子觉大于约4°，视觉处于足够高的明视水平，且具有光谱功率分布，因此预计不会有视网膜的杆受体参与。

This document specifies colour-matching functions for use in colorimetry. Two sets of colour-matching functions are specified.— Colour-matching functions for the CIE 1931 standard colorimetric observer.This set of colour-matching functions is representative of the colour-matching properties of observers with normal colour vision for visual field sizes of angular subtense from about 1° to about 4°, for vision at photopic levels of adaptation.— Colour-matching functions for the CIE 1964 standard colorimetric observer.This set of colour-matching functions is representative of the colour-matching properties of observers with normal colour vision for visual field sizes of angular subtense greater than about 4°, for vision at sufficiently high photopic levels and with spectral power distributions such that no participation of the rod receptors of the retina is to be expected.
