Abstract
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.
