ABSTRACT:
A circuit is disclosed to simplify hardware of image transmission system such as a facsimile and also improve an encoding function. This circuit has a part for obtaining from a brightness change detector a brightness signal indicative of a change of brightness of binary valued data serially supplied from a data input part, and providing a detection load data to a storage part in response to generation of said detection signal. Accordingly, the storage part generates a within-line position value for said binary valued data having a change of brightness in response to the detection load data.
