A plurality of analog memory devices alternately store successive one-line segments of facsimile signals. During the write-in period of one memory, the signals of one-line segments are stored while the immediately preceding one-line segment is read out of the other memory and processed to make an amplitude comparison for each picture element. The amplitude comparison is translated into a width of an output pulse for each picture element, which width also reflects the time duration of the facsimile recording paper. Thus, a picture is reproduced with a gradation of shade values. |
