Abstract：
 This invention relates to a parallax computing method for video images in a multi-viewing point system, which utilizes a block matching method to compute the complete parallax of the first video image in the target video images takes the parallax value of the related image block in the above one target video image as the current position to carry out limit search and directional search to the reference video image, if the correspondent image block is searched, then the parallax is got, if not, the search is continued to the end, the parallax is got by fetching the image block with the smallest mean pixel gray difference in the target video images as the corresponding block.
