The present invention provides an improved method and device for generating a depth map (112) by extracting three-dimensional depth information from the movement vectors of an encoded video bit stream (102) to display two-dimensional video sequences onto three- dimensional displays. In particular, the invention performs depth extraction (110) by means of a post-processing of the movement vectors of the inter-coded macroblocks, which have been already encoded in the video bit stream, thereby significantly reducing the heavy processing requirements associated with conventional motion estimation techniques. |
