Abstract
A reference picture signal is stored defining a plurality of image pixels of a reference picture. The input picture signal is divided into a plurality of input block signals each defining a plurality of image pixels of a corresponding input block. Decimation information is set in advance for specifying a portion to be decimated among the plurality of image pixels of each input block. Selected image pixels of each of input blocks are addressed in accordance with the block decimation information to obtain a corresponding decimated input block having an addressed subset of image pixels relative to the plurality of image pixels of each input block. An image motion associated with each input block is estimated by comparing the addressed subset of image pixels of each corresponding decimated input block with the image pixels of the reference image.
