ABSTRACT:
A motion vector estimating apparatus includes a plurality of block matching estimators generating block matching values from an input video signal respectively. The block matching values represent likelihoods of motion vectors with respect to an actual motion respectively. Each of the block matching values is periodically reset. A plurality of convolution adders receive the block matching values respectively. Each of the convolution adders provides predetermined weights to the block matching values and adds the weighted block matching values to obtain an output value. The smallest of the output values from the convolution adders is selected and a vector related to the smallest values is outputted as a final motion vector.
