Claim One:
1. A method of determining motion vectors which are assigned to individual image regions (E 1 x , E 2 x , E 3 x , E 4 x ) of an image (P), wherein image (P) is subdivided into a number of rectangular image blocks (a-d, x, e-h), and a motion vector is assigned to each image block (a-d, x, e-h), the method comprising: defining a corner region (E 1 x ) located in a corner of a selected one of the image blocks (a-d, x, e-h); determining the image blocks (a, b, d) adjacent to this corner region (E 1 x ); determining whether the motion vectors assigned to the image blocks (a, b, d) adjacent to the corner region (E 1 x ) form a homogeneous vector field; and generating a motion vector for the corner region from the motion vectors of the selected adjacent image blocks (a, b, d) when the motion vectors of the adjacent image blocks form a homogeneous vector field.
