Abstract
A method is disclosed in for presenting an endoscopic image in an upright orientation. An electronic rotation pick-up means is fixed to the housing of an endoscope. The electronic rotation pick-up means produces signals indicating rotations of the endoscope. A microprocessor uses these signals to calculate a necessary amount of rotational correction for the endoscopic view orientation. The calculation includes factors to account for endoscope roll, endoscope pitch, and endoscope viewing direction. An image rotator rotates the endoscopic image by the calculated correction amount. The rotated image is displayed on a video display device.
