ABSTRACT:
The present invention converts a wide-angle lens image into a two dimensional view with reduced distortion and warping. The present invention uses a graphics engine which accepts a shape, an image, and a viewing position. An effective lens shape, corresponding to the recording lens, an image as well as a image-related viewing position is supplied to the graphics engine. The graphic engine projects the image on the effective shape and displays a portion of the image from the viewing position. The recording lens is often a wide-angle lens. The graphics rendering engine maps the wide-angle lens image onto an effective lens shape and displays sections of the mapped image on the shape in a full screen view. Portions of or the entire image are viewable at any one time. Use of acceleration hardware permits frame per second rates of display of up to 60 and greater frames per second. Typical wide-angle recording lenses include “fisheye” lenses and torus shaped (doughnut) lenses.
