Abstract
PURPOSE: To make it possible to correct the color of only a desired color region independently by preventing color regions from overlapping with one another.
CONSTITUTION: A color region is divided into seven, and divided regions are prevented from overlapping with one another. R, B and G signals from a camera are inputted to corresponding terminals respectively, and R and G signals and R and B signals have signal levels adjusted by corresponding variable resistances so that prescribed outputs can be obtained by corresponding adders 101 and 102. They are inputted to NAM circuit 104 and are subjected from the output of adder 103 by 105, and further, they are subjected to black and white clip 106 and are so controlled that correction signals may be fixed independently of chroma saturation of the object by white clip and are inputted to dual differential amplifiers 107 and 108, and a red chroma saturation and a red phase can by changed by the former and the latter respectively. Other colors can be subjected to color correction independently in correspondence of their regions.
