Patent ID: 7113650

Claim:
A computer-implemented method for performing real-time correction of a wide-angle image, comprising: an acquisition step for obtaining pixel coordinates from the wide-angle image, hereinafter called wide-angle image pixel coordinates; a generation step for generating a warp table by applying a parametric image warping function to the pixel coordinates; and a warping step for warping the wide-angle image in real time using the warp table to create a corrected wide-angle image; wherein the generation step further comprises: a vertical scaling step for vertically scaling the wide-angle image pixel coordinates using the parametric image warping function to create vertically-scaled wide-angle image pixel coordinates; a horizontal scaling step for horizontally scaling the vertically-scaled wide-angle image pixel coordinates using the parametric image warping function to create a preliminary warp table containing preliminary pixel coordinates; and a correction step for performing horizontal distortion correction on the preliminary warp table using the parametric image warping function to create the warp table.
