<p>Apparatus for processing motion vectors associated with a digital television image comprises a vector filter (36) and a vector calculator (37) for deriving a plurality of motion vectors respectively representing the motion of a pixel in the image, a circuit (101, 104) for testing the accuracy of each motion vector by differencing pixels shifted in dependence on the motion vector from two successive fields of the image to a common position in a field interpolated between the two fields, and a vector selector (103) for selecting a motion vector from the plurality in dependence on the testing.</p> |
