Abstract
A method () and a system () for providing video signals to video displays includes the steps of receiving at least one input video signal (), dithering the non-uniformity color correction (), applying the non-uniformity color correction to the input video signal to generate a color corrected video signal (), and increasing a frame rate of the color corrected video signal (). Gamma correction () can be applied to the color correction. Generating a dithered non-uniformity color correction can include selecting from a data storage () a plurality of RGB correction matrices (), measuring at least one brightness level of the input video signal, selecting for the picture level correction a first RGB correction matrix if the brightness is within a first range of values (), a second RGB correction matrix if the brightness is within a second range of values (), and interpolating () the plurality of RGB correction matrices if the brightness is within a third range of values.
