  • Apparatus and method for stabilizing an image from an endoscopic camera
    Publication number: 20080108870
    Abstract: A video camera unit used with an endoscope is provided with sensors sensing an ambient field to detect rotation of the camera unit about an axis causing rotation of an image generated from the output signal of the camera unit. This output signal is modified to produce a stabilized video signal, producing an image held at a preferred angle. In one embodiment, two ambient fields, such as gravity and a magnetic field are alternately used.
