  • Patent number: 4296439
    Abstract: In a digitalized facsimile transmission system, (k) number of scanning lines (k=2 or 4) are encoded to a relative address code and the next scanning line is encoded to a run length code, and each scanning line has the related synchronization code pattern corresponding either said relative address code or said run length code. Thus, the effect of a transmission error is restricted within one scanning line when that error occurs in the scanning line encoded to run length code, or k lines when that error occurs in the scanning line encoded to relative address code. The value (k) is switched between k=2 and k=4 according to the instantaneous quality of a communication line. When the quality is good, k=4 is selected, and when the quality is bad, k=2 is selected. The reception side can switch the decoding systems between relative address decode and run length decode, by being controlled through the related synchronization code patterns.

  • Patent number: 4258392
    Abstract: A coding method for a two-level facsimile signal by the use of the two-dimensional coding principle, in which when successively coding addresses of a facsimile signal representative of the positions of information change picture elements, each having a binary level different from that of an immediately preceding picutre element, the above-mentioned addresses on each coding scanning line are classified into three modes that are determined by the states of information change picture elements on the coding scanning line and on a reference scanning line immediately preceding the coding scanning line. The above two-dimensinal coding principle and a one-dimensional coding principle may be adaptively adopted to shorten the transmission time and to lessen the influence of a transmission error.

  • Patent number: 4212035
    Abstract: A facsimile signal coding system, in which a facsimile signal is divided into a plurality of scanning line groups each including a predetermined number of scanning lines. A substantially central one of the scanning lines of each group is encoded by a coding method without referring to information of a scanning line adjacent to the central scanning line. Information of the remaining lines above the central scanning line is sequentially encoded upwardly from the central scanning line using information of the just precedently encoded line as reference information. Information of the remaining lines below the central scanning line is sequentially encoded downwardly from the central scanning line using information of the just precedently encoded line as reference information.

  • Patent number: 4134133
    Abstract: A method for interline-coding a facsimile signal, in which information of scanning lines of the input facsimile signal is alternately divided into information of at least one first unit line and information of at least one second unit line. A first one of the first unit lines is first coded in accordance with a predetermined coding principle. The information of the next one of the first unit lines is secondly coded in accordance with a predetermined coding principle prior to coding of information of the first one of said second unit lines. The information of the first one of the second unit lines is thirdly coded by two-dimensional predictive coding using, as reference information, the information of the first one and the next one of the first unit lines. The operations of the second coding and the operation of the third coding are repeatedly achieved thereafter.

  • Patent number: 4115815
    Abstract: A facsimile signal coding method, in which information change picture elements are classified into two kinds of change points according to the information change directions. In case of the information change picture element having an information change from white to black, the relative distance between an instant information change picture element and a reference information change picture element selected from information change picture elements on the same scanning line or at least one immediately preceding scanning line is coded. In case of the information change picture element having an information change from black to white, the distance between an instant information change picture element to be coded and the immediately preceding information change picture element is predicted on the basis of information of a run already coded, so that an error between the predicted value and the run length of the instant run is coded.
