Title:
ENDOSCOPE SYSTEM AND WHITE BALANCE ADJUSTING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/202847
Kind Code:
A1
Abstract:
An endoscope system (100) includes: a light source unit (2) that supplies illumination light to an endoscope (1); an acquisition unit (12) that acquires a reference white balance coefficient from the endoscope (1) or a predetermined device; a storage unit (11) that stores correction information; and a calculation unit (13) that calculates a correction white balance coefficient by correcting the reference white balance coefficient using the correction information. The light source unit (2) generates the illumination light from a plurality of rays of light output from a plurality of solid state light sources (9R, 9G, 9B). The reference white balance coefficient is a coefficient for adjusting white balance of an image of a subject illuminated with reference illumination light, and the correction information is information based on the difference between wavelength characteristics of the reference illumination light and wavelength characteristics of the illumination light.
