ABSTRACT:
An endoscope system includes a plurality of different endoscopes each of which has an illumination optical system for emitting light outward, an observation optical system for forming an optical image of a subject at the distal end of an insertion tube which can be inserted into the subject, and a solid-state imaging device for converting the optical image of the subject formed by the observation optical system into an electric signal, a plurality of different signal processors each of which drives a solid-state imaging device and processes the output signal sent from the solid-state imaging device to provide a video signal, and a plurality of different light sources each of which is compatible with one of the plurality of different endoscopes and supplies light to the illumination optical system. The system expendability is so excellent that the above equipment will be compatible with technologically-upgraded endoscopes, signal processors, or light sources.
