ABSTRACT:
The invention concerns a color image communication apparatus, which comprises scan conversion means for converting n-level image data received in a raster scan system via a communication line to data in a shuttle scan system, multi-level conversion means for converting color n-level data obtained from the scan conversion means for multi-level data, and color conversion means for converting color characteristics of multi-level data obtained from the multi-level conversion means from color characteristics for a communication line to color characteristics of output color recording means. The invention also concerns a color image communication apparatus, which comprises means for generating shuttle system color signal, color conversion means for converting the color signal to signal matched to standard color characteristics for a communication line, n-level conversion means for converting the converted color signal from the color conversion means to n-level signal, and means for performing data scan conversion of the n-level data from shuttle scan system to raster scan system and sending out the raster scan system n-level data to the communication line.
