ABSTRACT:
An image processing system adjusts a video signal representing a captured image of an object to compensate for an offset camera. The camera generating the video signal is offset from the object of the captured image. The system determines an offset measure between the camera and the object of the captured image. Based on the offset measure, the image processing system adjusts the video signal generated by the camera. The offset measure is determined by calculating the angular difference between a focal plane associated with the camera and an image plane associated with the object of the captured image. The video signal is adjusted by compressing portions of the video signal associated with the regions of the object located closest to the camera and expanding portions of the video signal associated with the regions of the object located farthest from the camera.
