Abstract
The present invention provides an improved method and device for generating a depth map () by extracting three-dimensional depth information from the movement vectors of an encoded video bit stream () to display two-dimensional video sequences onto three-dimensional displays. In particular, the invention performs depth extraction () 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.
