PROBLEM TO BE SOLVED: To provide a brightness/chromaticity measurement device with a CCD image sensor capable of more correctly evaluating the brightness or chromaticity in the case of guiding the measurement light through a plurality of optical fibers and detecting it by the CCD image sensors. SOLUTION: The light of a luminescent body is transferred through a plurality of optical fibers and received by the monochromatic CCD through an optical lens for imaging the ends of the optical fibers at once. In front of the CCD image sensor (between the optical lens and the CCD image sensor) an optical filter is arranged, wherein the performance of the optical filter (filter transmittance) is considered on the spectrum sensitivity of the receiving light path system.
