Patent ID: 7876955

Claim:
An image processing system comprising: an image capturing unit; an image processing unit; and a display unit, the image capturing unit comprising: a plurality of illuminating light sources which emit illumination lights having a plurality of different spectroscopic distribution characteristics; an image pick-up optical system which forms an image of a subject illuminated by the illuminating light sources; and an image pick-up device which picks up the subject image formed by the image pick-up optical system and outputs an image signal; the image capturing unit interlocking the plurality of illuminating light sources with an exposure timing of the image pick-up device, selectively lighting-on the plurality of illuminating light sources, and thus obtaining a plurality of subject spectroscopic images, the image processing unit comprising: an image identification calculating unit which calculates grade data related to a color of the subject based on at least one subject spectroscopic image of the plurality of subject spectroscopic images obtained by the image capturing unit; and a color reproduction calculating unit which calculates display image data by estimating image data having XYZ tristimulus values based on the subject spectroscopic images obtained by the image capturing unit, using an input profile related to the image capturing unit and a color matching function, and the display unit displaying the grade data and an image which is color-reproduced based on the display image data.
