Color-Correction Techniques — Analog and Digital

David E. Acker

Color-correction systems allow the operator to change the hue quality of the picture to compensate for several conditions that may have existed when a program originated. These include rebalancing of black and white levels, changing the gamma characteristic, compensating for lighting conditions, and modifying the overall scene colorimetry to create a particular mood. This article presents the theory of operation for a color-corrector system and compares analog and digital implementations.
