Abstract: The present invention relates to a stereo image compensating apparatus and a method thereof. The stereo image compensating apparatus according to an embodiment of the present invention includes: an image obtaining unit which obtains a reference image and a target image which are photographed from different angles about an object; a histogram generating unit which generates a color histogram about each of the obtained images; a color area dividing unit which divides the generated color histogram into one or more color areas; and an image compensating unit which matches the target image with the color area of the reference image and compensates the target image using the average RGB value of a pixel which corresponds to the same color area. By the aforementioned, the present invention is able to compensate color more precisely while maintaining a unique brightness difference between areas by compensating the color only in between the same color areas by dividing an image using the color histogram for two images for an object.
