PROBLEM TO BE SOLVED: To provide an accurate colorimetric value with a simple device.;SOLUTION: This colorimetric device is provided with a spectral reflectance measurement section 20 for radiating the measurement light to a sample to measure the spectral reflectance and a three-stimulus value calculation section 30 calculating W to satisfy the relation W=W0+(Eil-Ecp)×(Wu-Wuv)/Eu, where W is a three-stimulus value obtained when the first and second measurement light are radiated to a fluorescent sample 40 including a fluorescent material, the measured first and second spectral reflectance are inputted, and the observation light is radiated to the fluorescent sample 40, Eil is the observation light excited energy obtained when the fluorescent material is excited by the observation light, Ecp is a prescribed correction coefficient, Eu is the measurement light excited energy obtained when the fluorescent material is excited by the first measurement light, Wu and Wuv are the three-stimulus values obtained when the first measurement light is radiated to the virtual first and second materials, and W0 is the three-stimulus value obtained when the observation light is radiated to the second material.;COPYRIGHT: (C)2001,JPO
