Michael P Buchin: Video imaging system with image processing optimized for small-diameter endoscopes. Origin Medsystems, Limbach & Limbach, December 12, 1995: US05475420 (48 worldwide citation)

An output video signal is derived from an input video signal generated by an image sensor in response to an image formed on only part of the image sensor. The output video signal is derived in response to only the portion of the input video signal generated by the part of the image sensor on which t ...
