摘要： A first irradiation portion that radiates white light onto a subject, a second irradiation portion that radiates narrow bandwidth light having a narrower wavelength bandwidth than the white light, and an observation window used to observe the subject are respectively disposed on a leading end surface of an endoscope insertion portion. Each of the first and second irradiation portions includes a pair of irradiation windows for emitting light therefrom. A straight line passing through a center point of the observation window and bisecting the leading end surface is defined as a boundary line. The pair of irradiation windows of the first irradiation portion are disposed on both sides of the boundary line. The pair of irradiation windows of the second irradiation portion are disposed on the both sides of the boundary line. Spectra of lights radiated from the irradiation windows of the second irradiation portion can be changed individually.

摘要： An electronic endoscope includes an illumination unit, an imaging unit and an image generating unit. The illumination unit switches among plural light beams having different spectra so as to illuminate a subject. The light beams include white light and excitation light for exciting the subject to produce fluorescence. The imaging unit includes a solid-state imaging device, and an objective optical system. The objective optical system guides, to the solid-state imaging device, light returning from the subject which the illumination unit illuminates. The image generating unit generates image data based on image signals output from the imaging unit. The solid-state imaging device further includes a sensitivity adjusting unit that only lowers sensitivity, to the excitation light, of pixels which are sensitive to the fluorescence among a plurality of pixels of the solid-state imaging device. The light guided by the objective optical system is incident directly onto the solid-state imaging device.
