ABSTRACT:
A method (400) and a system (100) for providing video signals to video displays includes the steps of receiving at least one input video signal (150), dithering the non-uniformity color correction (445), applying the non-uniformity color correction to the input video signal to generate a color corrected video signal (450), and increasing a frame rate of the color corrected video signal (120). Gamma correction (125) can be applied to the color correction. Generating a dithered non-uniformity color correction can include selecting from a data storage (115) a plurality of RGB correction matrices (300), 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 (425), a second RGB correction matrix if the brightness is within a second range of values (435), and interpolating (440) the plurality of RGB correction matrices if the brightness is within a third range of values.
