Abstract
PURPOSE: To decrease the number of the control signal and thus to reduce the time for transmission by transmitting the control signal when the picture element signals in the block are all white and transmitting the picture element signals in the block after modulation when the picture element signal contains the black signal respectively, thus increasing the SIN.
CONSTITUTION: The picture element signals read out through original reading device 11 are stored in sequence into line memory 13, and then led out from memory 13 to be applied to 1-block memory 14 for isolation into blocks. In case the picture element signals in the block are all white signals, the control signal which can be distinguished from the picture element signal is transmitted in place of transmission of the picture element signals belonging to the block. While in case the picture element signals in the block contains the black signal, the picture element signals in the block are transmitted after modulation 20. As a result, the number of the control signals can be decreased, reducing the time for transmission. Thus the SIN can be increased.
