Abstract
A color video endoscope system having a control unit compatible with various endoscopes. Each endoscope generates unique signals to the control unit to optimize the clocking out of data from the solid state image sensor, to optimize the processing of data received from the image sensor, and to identify the size and location of the image formed on the image sensor so as to control the image formed on the monitor. The control unit generates alternating fields of red, green and blue light through the endoscope light guide with blank fields between the color fields, during which time data is clocked out of the image sensor, thereby preventing image "smear" caused by immediately successive color fields.
