ABSTRACT:
Color correction method and processor for improving the quality of color reproduction in a color picture recording unit or display unit in a color copy machine, a color facsimile or a color printer. A memory means previously stores in a table values of secondary color correction image data used for recording corresponding to values of primary image data produced through a color scanning of a color picture. The secondary color correction image data are read out from the table by addressing signals formed from the three color components of the primary image data. Data bits for the addressing signals of the three color components of the primary image data are assigned unevenly depending on the contribution factor of each in forming the three color components of the secondary color crrection image data, thereby reducing the required number of addressing bits and associated memory.
