Abstract

PURPOSE: To obtain a device which gives coding or decoding to the ordinary document pictures.
CONSTITUTION: Picture signal (I) supplied from the signal line receives an exclusive logic sum operation at logic circuit 18 with scramble signal (II) generated from signal generation circuit 19, and this result is deliverd in the form of cnversion signal (III). Signal (III) is the exclusive logic sum between signals (I) and (II), and at the same time signal (I) is also the exclusive logic sum between signals (II) and (III). This is manifest by the equations. Accordingly, the original picture can be restored from the picture which is converted from the original picture and then recorded through an exactly same means as that of the conversion time.
