ABSTRACT:
The disclosure concerns a device for estimation of movement by block matching in an image compression system based on blocks, characterized in that it comprises N lines.times.M columns of means of calculation of an error function between two values, N.times.M means of memorization of values representing the block whose movement is to be estimated, N.times.M means of memorization of values representing a block of a reference window, the two means of memorization being linked respectively to the means of calculation, M means of adding that totalize simultaneously the values of the error function for a column of N elements of calculation. The invention is applicable to image compression.
