ABSTRACT:
A circuit and method for optimizing the display of a video signal on a display. Control of the display's brightness and contrast is based on aspects of a video signal, such as the average amplitude of the signal and the standard deviation. These aspects of the video signal are determined and the video signal manipulated based on the determined characteristics such that the resultant video signal is optimized to the dynamic range of the display.
