摘要:
A method and apparatus for transmitting code data of a multi-color subject copy from a transmitter to a receiver in a manner that minimizes the volume of code data. The form of the data is determined by the capabilities of the receiver. The original images consist of at least two colors in addition to the background color of the copy sheet. A transmitter scans each line of the copy sheet to develop scan signals corresponding to the original images. The scan signals are used to prepare sets of run length code data and color discrimination code data indicative of the colors which appear in each line of the subject copy sheet. The transmitter transmits color discrimination code data and the corresponding set of run length code data to a receiver adapted to reproduce the transmitted data. The method of combining the scan signals to create the transmitted image signals and color discrimination code produce a condensed data strength.
