Patent ID: 8553077

Claim:
A endoscope system comprising: an endoscope that includes an illumination optical system with a fluorescent body formed in an optical path and an imaging optical system with an imaging element outputting an imaging signal of an optical image; and a control device that includes a light source unit which supplies an excitation light to the illumination optical system so as to emit light from the fluorescent body and an image processing section which corrects the imaging signal output from the imaging element, wherein the image processing section includes: an illumination light spectrum calculating unit for calculating an illumination light spectrum obtained by the illumination optical system based on individual information of light emission characteristics of the fluorescent body provided in the endoscope connected to the control device and individual information of light emission characteristics of the light source unit; a chromaticity correction table creating unit for creating a chromaticity correction table to correct chromaticity information of the imaging signal based on a difference between the spectral characteristics profile of the standard light and the spectral characteristics of the actual illumination light; and an image correcting unit for correcting the imaging signal output from the imaging element by referring the created chromaticity correction table.
