適用范圍：This International Standard specifies colour-matching functions for use in colorimetry. Twosets of colour-matching functions are specified.a) Colour-matching functions for the CIE 1931 standard colorimetric observerThis set of colour-matching functions is representative of the colour-matching properties ofobservers with normal colour vision for visual field sizes of angular subtense from about 1° toabout 4°, for vision at photopic levels of adaptation.b) Colour-matching functions for the CIE 1964 standard colorimetric observerThis set of colour-matching functions is representative of the colour-matching properties ofobservers with normal colour vision for visual field sizes of angular subtense greater thanabout 4°, for vision at sufficiently high photopic levels and with spectral power distributionssuch that no participation of the rod receptors of the retina is to be expected.
