ABSTRACT:
A method of processing data in matrix arrays in a motion estimation system is characterized in that each array (803, 804) performing a calculation of distortion (Err) for a block of pixels (1, 2) of a current image, at least two arrays (803, 804) being arranged in series performing the calculations for at least two adjacent blocks (1, 2) of the said current image, the reference window corresponding to the entirety of these blocks being introduced in bands of pixels into the first of the said arrays (803) and propagating from array to array in the said series of arrays, the allocation of the blocks (1, 2) to the arrays and the direction of introduction of the band into the arrays being such that the last part (c, respectively A) of the band introduced into the array corresponds to a part of the window of the block (2, respectively 1) allocated to the first of the arrays (803).
