Abstract

See full text

The spectrophotometer of the present invention measures a spectral reflectance of an object to be measured to thereby determine a color value of the object to be measured based on a color-matching function of an XYZ color system and the spectral reflectance. The spectrophotometer includes an irradiation unit configured to irradiate the object to be measured with light having a spectral intensity distribution in which a relative intensity at a wavelength at which the value of z reaches its peak in the color-matching function is equal to or greater than 0.5.
