Abstract
A color control simulator for a picture reproducing machine, comprising an operational processor including a program having the same operational functions, but not the same operational circuits, as those of the picture reproducing machine, and adjusting means for adjusting color control conditions for the picture reproducing machine, which correspond to those of the picture reproducing machine. A color picture signal picked up is separated into color separation analog signals in a color separator, and then color separation digital signals, and the color separation digital signals are operated in the operational processor to obtain the color control conditions by the adjusting means. The color control conditions may be recorded in a card or a tape in output display means.
Claims6
For use in conjunction with a predetermined, color corrected picture reproducing machine, a color control simulator of the picture reproducing machine, comprising:
- a color separator adapted to scan and pick up a picture signal from an original picture and separate the picture into color separation analog signals which are converted into corresponding color separation digital signals;
- an operational processor equivalent to that of the predetermined picture reproducing machine operating under a preselected program for processing the color separation digital signals to generate color correction digital signals in order to obtain desired color control conditions for the picture reproducing machine;
- and
- adjusting means for adjusting the color control conditions, in the simulator in a form and format compatible with and corresponding to those of the picture reproducing machine for enabling rapid setup of a picture reproducing machine to create color separations of the original picture.
