Abstract

PURPOSE:To increase an effect by a data compression processing which is executed in the following process, by executing a pre-processing to a picture information which has been sampled, in a two-dimensional and binary picture signal of a facsimile signal. CONSTITUTION:A picture data is inputted in series to a shift register 1(11-14), and also is inputted to a 5X5 array picture element constitution part 2 A memory data from the 5X5 array picture element constitution part 2 is inputted to an N(X) operation part 3, in which N(X) is derived and is sent to a smoothing processing part 4. The smoothing processing part 4 executes the smoothing operation by use of a picture information, too, from a 3X3 matrix part 21 in the 5X5 picture element constitution part 2, and outputs it.
