Claim One:
1. A device for motion compensated compression of a video sequence, comprising: a first storage block which stores a reference image included in the video sequence, a receiving block which receives a next image included in the video sequence, and a determination block for determining a plurality of motion vectors, whereby each motion vector corresponds to a next point in a next image surface corresponding to the next image, for estimating changes between the next image and the reference image, a compression block which compresses the video sequence using the motion vectors, an establishment block for establishing information about a first depth map and first camera parameters corresponding to the next image, and a second storage block for storing information about second camera parameters corresponding to the reference image, wherein the determination block is further arranged to determine each motion vector corresponding to a next point in the next image surface by: projecting the next point to a projected point in a three-dimensional space using the first depth map and first camera parameters, projecting the projected point to a reference point included in a reference image surface corresponding to the reference image using the second camera parameters, determining an estimated vector corresponding to the next point based on a location of the next point in the next image and a location of the reference point in the reference image, and determining the motion vector corresponding to the next point using the estimated vector.
