ABSTRACT:
The invention relates to a device for blockwise estimation of motion. This device includes on the one hand a matrix array (300) for calculating an error function, the said array including storage elements (S, 406, 407) for plural blocks (a, a') of current pixels and means (403) for switching between the storage elements corresponding to the various blocks and on the other hand a memory (801) for feeding the said array with pixels of a search window, linked to the said array.
The device according to the invention is characterized in that
