CIE Standard Illuminants and Sources | SpringerLink
网页2015年1月1日 · Illuminants are used in colorimetry to compute the tristimulus values of reflected or transmitted object colors under specified conditions of illumination. The term “source” refers to a physical emitter of light, such as a lamp or the sky.
White point - Wikipedia
网页The white point of an illuminant is the chromaticity of a white object under the illuminant, and can be specified by chromaticity coordinates, such as the x, y coordinates on the CIE 1931 chromaticity diagram (hence the use of the relative SPD and not the absolute SPD, because the white point is only related to color and unaffected by intensity).
