Patent ID: 8502980

Claim:
A spectral characteristic measuring system which obtains spectral characteristics of a color sample by using an illumination light from a semiconductor light-emitting element, said spectral characteristic measuring system comprising: a measurement control section that controls a measurement section so as to measure a spectral distribution L 1 corresponding to said illumination light to obtain a spectral distribution D 1 of said illumination light, then measure a spectral distribution Lx of a reflected light or a transmitted light reflected by or transmitted through said color sample illuminated by said illumination light, and then measure a spectral distribution L 2 corresponding to said illumination light to obtain a spectral distribution D 2 of said illumination light; an interpolation section that estimates a spectral distribution Dx of said illumination light at the time when said spectral distribution Lx of the reflected light or the transmitted light reflected by or transmitted through said color sample illuminated by said illumination light is measured, by interpolating said spectral distribution D 1 obtained based on said spectral distribution L 1 and said spectral distribution D 2 obtained based on said spectral distribution L 2 ; and a spectral characteristics computation section that obtains spectral characteristics Cx of said color sample based on said spectral distribution Lx and said spectral distribution Dx.
