  • Endoscope system for simultaneously displaying two endoscopic images on a shared monitor
    Patent number: 5196928
    Abstract: An endoscope system comprises first and second endoscopes each of which includes an elongated insertion tube and an imaging device, a light source for supplying illumination light to the endoscopes, a function for processing a signal originating from one of the imaging devices, and a video processor which mixes the signal with at least a signal sent from an external input terminal and outputs a given video signal corresponding to the first and second endoscopic images.
