Claim Text:
1. A multi-view synthesizer comprising: a first depth generator that generates a first depth map by stereo-matching a first stereo image to a second stereo image; a consistency checker that generates a stereo-matching rate indicating a quality of the first depth map, the consistency checker comparing matched pixel locations when starting with the first stereo image to pixel locations when starting with the second stereo image to generate the stereo-matching rate; a second depth generator that generates a second depth map from no more than one single view image; a disparity fallback selector that selects the second depth map as a selected depth map instead of the first depth map when the stereo-matching rate is below a matching threshold; a forward mapper that shifts sub-pixels from a source image by an offset to generate a destination image, the offset being read from or generated from the selected depth map, wherein the offset is scaled to a different value for each view image in a plurality of multi view images output as the destination image; and a backward mapper that reads a plurality of view masks to locate a selected view mask that generates a sub-pixel location in the destination image, and locates a source sub-pixel in the source image using a view offset for the selected view mask, the backward mapper generating the destination image by copying the source sub-pixel to the sub-pixel location in the destination image.
