Colorimetry - Part 1: CIE standard colorimetric observers

active, Most Current
Organization: CEN
Publication Date: 1 July 2019
Status: active
Page Count: 44
ICS Code (Colours and measurement of light): 17.180.20
scope:

This document specifies colour-matching functions for use in colorimetry. Two sets of colourmatching functions are specified.

a) 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.

b) 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.
