Patent ID: 8624966

Claim:
An endoscope apparatus comprising: an endoscope which includes an imaging optical system comprising an imaging element and an illumination optical system comprising an illumination window, the optical systems being provided at a front end of an endoscope insertion unit inserted into a body cavity; a control unit which includes a light source unit connected to the endoscope and supplying at least excitation light to the illumination optical system so as to emit light from a fluorescent substance, and an image processing section correcting an image signal output from the imaging element on a basis of a predetermined color correction table and outputting a result thereof; an endoscope support unit which supports the endoscope in a suspended state; a bottomed cylindrical body which is supported by the endoscope support unit; and a cover which covers an upper portion of the bottomed cylindrical body, and includes a light shielding property, wherein the endoscope apparatus further comprises a storing unit that stores the color correction table, wherein the control unit performs a calibration process that an image of a color chart comprising a plurality of color patches with known chromaticity values is captured by the imaging element, chromaticity for the plurality of color patches is obtained from an imaging signal of the color chart so as to be used as a measured chromaticity value, and contents of the color correction table stored in the storing unit are changed so that the measured chromaticity value of the color patches is equal to the known chromaticity value, wherein the color chart is disposed so as to face a front end of the endoscope insertion unit which is supported by the endoscope support unit in a drooped state, wherein the color chart is disposed at a bottom surface of the bottomed cylindrical body which accommodates the front end of the endoscope insertion unit in an inside of an inner peripheral surface thereof, and wherein an insertion hole is perforated in the cover so as to allow the front end of the endoscope insertion unit to be inserted thereinto.
