1. A method to enhance motion estimation, said method comprising the step of:

  • selecting a displacement vector as a best motion vector for a region in a field from a plurality of at least two candidate motion vectors by applying an error function to each of said plural candidate motion vectors, wherein the candidate motion vector with the least error is selected as the displacement vector for the region in the field;

    wherein said error function comprises a first penalty term that depends on said candidate motion vector either as calculated in a current frame or as calculated in a previous frame and a second penalty term that depends on the position and size of said candidate motion vector.
