22、 CIE Standards are therefore a primary source of internationally accepted and agreed data, which can be taken, essentially unaltered, into universal standard systems. This CIE Standard replaces ISO/CIE 10527:1991 and was approved by the CIE Board of Administration and the National Committees of the
23、CIE. This CIE Standard has been prepared by CIE Division 2 “Physical measurement of light and radiation“. This standard contains only minor changes from the previous standard, in particular the values in the tables of the colour matching functions and chromaticity coordinates of the CIE 1931 and 196
24、4 standard colorimetric observers are identical with the previous standard, but it has now been clarified that they apply for standard air. TABLE OF CONTENTS FOREWORD v INTRODUCTION 1 1.

29、SICOLORIMETRY - PART 1: CIE STANDARD COLORIMETRIC OBSERVERS INTRODUCTION Colours with different spectral compositions can look alike. An important function of colorimetry is to determine whether a pair of such metameric colours will look alike. The use of visual colorimeters for this purpose is hand
30、icapped by variations in the colour matches made amongst observers classified as having normal colour vision. Visual colorimetry also tends to be time-consuming. For these reasons, it has long been the practice in colorimetry to make use of sets of colour-matching functions to calculate tristimulus
31、values for colours: equality of tristimulus values for a pair of colours indicates that the colour appearances of the two colours match, when they are viewed in the same conditions by an observer for whom the colour-matching functions apply. The use of standard sets of colour-matching functions make
32、s the comparison of tristimulus values obtained at different times and locations possible. 1. SCOPE This International Standard specifies colour-matching functions for use in colorimetry. Two sets of colour-matching functions are specified. a) Colour-matching functions for the CIE 1931 standard colo
33、rimetric 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
34、 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 pow
35、er distributions such that no participation of the rod receptors of the retina is to be expected. 2.
