Abstract: The present invention relates to a correction apparatus for a binocular disparity image and a method thereof and, more specifically, to a correction apparatus for a binocular disparity image and a method thereof capable of correcting the binocular disparity image by converting an invalid pixel which is generated in the binocular disparity image which is generated through a stereo matching of a local mode into a valid pixel. The correction apparatus for a binocular disparity image, which is provided by the present invention for the forementioned, includes: an input unit which receives a binocular disparity image; a validity judging unit which detects a pixel (invalid pixel) which has an invalid binocular disparity value by judging the invalidity of the binocular disparity value of each pixel in the binocular disparity image which is received by the input unit; a brightness difference calculating unit which calculates a brightness difference between a surrounding pixel and the invalid pixel detected by the validity judging unit; a distance calculating unit which calculates a distance between the surrounding pixel and the invalid pixel detected by the validity judging unit; a depth similarity calculating unit which calculates a binocular disparity value difference between the surrounding pixel and the invalid pixel detected by the validity judging unit; a weighed value calculating unit which calculates a weighed value by multiplying the brightness difference calculated by the brightness difference calculating unit, the inter-pixel distance calculated by the distance calculating unit, the binocular disparity value difference calculated by the depth similarity calculating unit; and a correction unit which corrects a binocular disparity value of a pixel which has the greatest weighed value among weighed values which are calculated by the weighed value calculating unit with a binocular disparity value of a central pixel.
