ABSTRACT:
An asynchronous color separation system comprises a plurality of picture input units for supplying a set of color-separated picture signals corresponding respectively to color components to be subjected to color tone controls. A scanner data processor is provided for selectively receiving the set of color-separated picture signals from the plurality of picture input units and contains at least one set of look-up tables adapted to carry out desired color tone controls on the thus-received set of color-separated picture signals. A plurality of picture reproducing units includes at least one central processing unit. The central processing unit selectively controls the distribution of color separated picture signals from the scanner data processor to the various reproducing units in accordance with a predetermined order of preference. The reproducing units provide a reproduced permanent or temporary picture. The scanner data processor may include a plurality of sets of look-up tables corresponding to the plurality of picture input units.
