Abstract
An apparatus and method for facilitating a subsequent choice of a motion vector from a plurality of candidate motion vectors in a motion estimation method, include receiving video image data from first, second and third consecutive groups () of image data. A first image part () of the first group of image data (), a second image part () of the second group of image data (), and a third image part () of the third group of image data () are identified, wherein the positions of the three image parts () correspond to a motion trajectory that is indicated by a candidate motion vector. A first error measure is then calculated by testing for differences between the first image part () and the third image part () and quantified as a first error measure. A second error measure is calculated by testing for differences between either the first image part () and the second image part () or the second image part and the third image part and quantified as a second error measure. An output error measure is then quantified, wherein the output error measure is derived from either the first or the second or a combination of both error measures.
