ABSTRACT:
A decimation device for digital data sequences includes a multiplexer mounted in cascade with a calculator producing, alternately, during a first calculation cycle, the mean M.sub.i of at least two data sequences representing the pixels P(i,j) and P(i,j+1) in a line L.sub.i, and during a following calculation cycle, the mean M.sub.c. The mean M.sub.c is composed of the mean M.sub.i and of an intermediate sequence previously calculated and stored in a storage register arranged between an output for the calculation stage and at least one of the inputs to the multiplexer. The intermediate sequence represents the mean M.sub.i-1 of at least two data sequences representing pixels P(i-1,j) and P(i-1,j+1) in a line L.sub.i-1, where i varies from 0 to N-1 and j varies from 0 to M-1.
