FACSIMILE COMMUNICATION SYSTEM ABSTRACT OF THE INVENTION A facsimile communication system for compressing, transmitting and reproducing facsimile information is provided, wherein a transmitter includes a correlation detector. When a first facsimile information scanned along a first scanning line has a low pattern density, the correlation detector determines by discrimination that at least one successive facsimile information, for example a second facsimile information scanned along a second scan- ning line adjacent to the first scanning line should be abridged. Then, the transmitter compresses the first facsimile information and a third facsimile information contained in a third scanning line, and the compressed first and third facsimile informations are transmitted to a remote receiver. The remote receiver also includes a correlation detector and the correlation detector deter- mines by discrimination that the compression-demodulated first facsimile information has a low pattern density. Then, the remote receiver supplies the first facsimile information to a recording device when it scans a first scanning line and, further, repeated first facsimile information is supplied to at least one successive scan- ning line, for example, to a second scanning line. There- after, the compression-demodulated third facsimile infor- mation is supplied to the recording device when it scans a third scanning line. - 1 -
