Abstract
An endoscope subsystem, for a video endoscope system of the type having an insertion tube employing a video sensor, an optical imaging system for forming images on the sensor, and a video display for displaying an image derived from the sensor, which subsystem is for electronically correcting the side-to-side image reversal of the image represented by signals derived from the sensor in response to light intensities in a scene viewed by the endoscope, which reversal may result from the use of a folded optic imaging system in order to achieve compactness in the distal end of the endoscope.
