ABSTRACT:
A method and arrangement are provided for motion estimation in a digitized picture having pixels, the pixels being grouped into picture blocks. The pixels can be grouped into at least a first picture area and a second picture area. First motion estimation is carried out in a first search area in order to determine a first motion vector. Furthermore, second motion estimation is carried out in a second search area in order to determine a second motion vector. The first search area and the second search area are of different sizes.
