Abstract
A motion estimator has a spatial sub-sampler to receive input images; at least one motion estimator determining motion vectors between input images and sub-sampled motion vectors between sub-sampled images; an up-sampler for up-sampling the sub-sampled motion vectors; and a selector for providing a motion vector output by selecting between the motion vectors and the (up-sampled) sub-sampled motion vectors, according to motion vector confidence.
