Abstract
A method and circuit for improving a video signal. They can be used to nullify the gamma correction applied at the broadcast end for cathode-ray tube signals when using a spatial light modulator display. Additionally, the method and circuit can be used to generally improve the quality of the display for computer monitors or other formats that do not require the gamma nullification.
