Abstract

Pixels in a digitized picture are grouped into picture blocks, which in turn are grouped at least in a first picture region and a second picture region. An overall motion vector is determined, through the use of which any shifting of the first picture region in comparison to the first picture region in a previous picture is described. The overall motion vector is allocated to all the picture blocks in the second picture region. A motion vector is determined for each of the picture blocks in the first picture region. The coding information of the picture blocks, the motion vectors and the overall motion vector are coded. A configuration for coding a digitized picture and a configuration for decoding a compressed picture are also provided.
