Abstract
A digital color correction system and method for correcting a color video signal representing a portion of a colored optical image by modifying the entire color space of each of the complementary colors which make up the color signal so that all objects which contain each color are modified at once. A correction means produces an output video signal having a plurality of complementary color components, each of which is related to a corresponding color component of the color video signal by a transfer function, and a modification means for independently modifying each of the transfer functions is provided. The entire color space for each color may be modified, or only selected portions of it. Thus, only objects falling within a desired range of the color space may be selectively modified.
