IMAGE TRANSMITTING SYSTEM OF ENDOSCOPE USING SOLID IMAGE SENSOR

摘要

A video signal transmission system for an endoscope converts an electrical video signal produced by a solid state image sensor into an optical signal and transmits the optical signal to a control section through a fiber optic cable or like light carrying medium. Because the fiber optic cable used for the present invention transmits light indicative of a time serial signal from the solid state imaging sensor, it will be clear that the cable may be constituted by a single length of optical fiber and, in this respect, substantially differs from usual light carrying fiber bundles which are installed in general endoscopes as image guides for transmitting light images simply as light.
