1. A system for image processing, comprising: a first circuit logic unit configured to read pixel coordinates from an original depth map; and a second circuit logic unit configured to compute a warped depth map on the basis of the original depth map, wherein the computing of the warped depth map is begun prior to completion of reading all of the pixels from the original depth map, wherein if the computing of the warped depth map results in a plurality of pixels at the same coordinates, then choosing the pixel in the plurality of pixels having the smallest depth for use in the warped depth map.
