Abstract
In an electronic endoscope system, a scope has an image sensor provided at a distal end thereof to generate image-pixel signals. A proximal end of the scope is connected to an image-signal processing unit, in which the image-pixel signals are processed to produce a video signal. A light source device is provided in the processing unit. An optical light guide extends through the scope. When the connection is established between the scope and the processing unit, the light guide is optically connected to the light source device. The light source device includes a white light lamp, and an ultraviolet lamp, and a mirror for selectively introducing either the white light or the ultraviolet light into the light guide.
