ABSTRACT:
A color correction technique is disclosed in which standardized color correction signals are stored in an addressable memory which emits a plurality of digitalized trichromatic picture scanning values as input values in a corresponding plurality of corrected picture recording signals as output values. An assignment of memory input to memory output is fed into the memory as standardized color correction data before reproduction. For a location to be specially corrected, the color signals thereof are measured and compared with predetermined values and a difference formation is provided between the memory output signals and the predetermined values, the difference values being stored and utilized, in connection with distance calculations of neighboring points, to input re-corrected color correction values into the addressable memory.
