소개하다
Colors with different spectral components may look similar. An important function of colorimetry is to determine whether a pair of such heterochromatic color stimuli look similar. The use of visual colorimeters for this purpose is hampered by variations in color matching between observers classified as having normal color vision. Visual colorimetry also tends to be time-consuming. For these reasons, colorimetry has long used a set of color matching functions to calculate the tristimulus value of a color: Equal tristimulus value of a pair of colors indicates that the color appearance of the two colors matches, when an observer applying the color matching function observes them under the same conditions. Using the standard set of color matching functions, it is possible to compare the tristimulus values obtained at different times and places.

1 범위
This document specifies the color matching function for colorimetry. Two sets of color matching functions are specified.

ㅏ) Color matching function of CIE 1931 standard colorimetric viewer.

This set of color matching functions represents the color matching properties of an observer with normal color vision, with a field of view size of about 1° to about 4° angular subtension, for vision at the level of clear vision adaptation.

비) Color matching function of CIE 1964 standard colorimetric viewer.

This set of color matching functions represents the color matching properties of observers with normal color vision, for field sizes with angular subtension greater than about 4°, and for visual and spectral power distributions with sufficiently high clear vision levels that no rod receptors of the retina are required to participate.
