Method and apparatus for improving the color rendition of color television receivers

摘要

A method and apparatus for improving the color rendition of a color television receiver includes variable gamma circuits for exponentially correcting the individual color signals. A user control is added to allow user control over the overall gamma of the color television receiver thereby rendering the colors more saturated. With the inclusion of this user gamma control, a separate control for brightness, which affects the overall bias on the CRT, is now obviated.
