Abstract:
1. A stereo image processing apparatus that computes a subpixel-level disparity between a target image and a reference image that form stereo images, the stereo image processing apparatus comprising: an extraction section that extracts a unit partial target image for subpixel estimation from the target image by applying a first window function at an extraction target position, and that extracts a unit partial reference image for subpixel estimation from the reference image by applying the first window function or a second window function that is set; a computation section that computes the subpixel-level disparity based on a phase difference between a data sequence including intensity values of the extracted unit partial target image for subpixel estimation and a data sequence including intensity values of the extracted unit partial reference image for subpixel estimation; and a window function setting section that sets, with respect to the extraction section, the second window function, which is formed by shifting the first window function based on the subpixel-level disparity computed by the computation section, wherein the computation section further:
