Abstract

PURPOSE:To obtain a picture with high quality, by transmitting outputs of three shift registers to an ROM and outputting a converted picture signal with a programmed converting algorithm, in a facsimile device coding and transmitting a picture signal of white/black binary value. CONSTITUTION:Line storage devices 21 and 22 make write or readout of a picture signal for one scanning line's share respectively, and the device 21 is for the picture signal of the converted previous scanning lines and the device 22 is used for the picture signal of the present scanning lines. On the other hand, shift registers 23-25 pick up in parallel picture signals for three picture elements' share required for the conversion from the inputted picture signals in time series. The picture signals picked up from the shift registers are inputted to a read only memory ROM 26, where the conversion algorithm is programmed and from which the cnverted picture signal is outputted. This output signal is written in the device 21 for the preparation of the conversion of the next scanning line and delayed 27 for one picture element's share and inputted to an ROM 25.
