  • Patent number: 7233367
    Abstract: An apparatus for and a method of continuously adjusting a brightness and a contrast of a video display. An analog video signal is converted to provide digital luminance (Y) signals and amplitudes of the digital Y signals are adjusted based on determining whether the digital Y signals of a frame have amplitudes corresponding to one or more of four regions of digital values. The four regions include a highest region, a second highest region, a lowest region and a second lowest region. Contrast is adjusted based on whether digital Y values of the frame are included for the highest region and/or the second highest region and brightness is adjusted based on whether digital Y values are included for the lowest region and/or the second lowest region.
