摘要： A light measuring device wherein a correct measured value can be obtained even if incident light varies in time or a luminance or brightness of an object for measurement is insufficient. The device comprises a branched optical fiber of a random specification having therein three mutually independent light transmission paths for introducing light from a common input end to three output ends. The input end of the optical fiber is located at a slightly defocused position of an objective lens while the output ends are individually opposed to three light receiving elements having different spectral sensitivities. Three components of light are simultaneously converted into electric signals and then into digital values by circuit means each including a double integration analog to digital converter. When a luminance is insufficient at a light receiving element, the gain of the associated analog to digital converter can be adjusted so as to assure appropriate measurement of light.
