Abstract:
Systems and methods are provided for reducing motion blur in a video display. A system for reducing motion blur in a video display may include a motion detection circuit and a luminance control circuit. The motion detection circuit may be used to compare a plurality of frames in a video signal to generate a motion detection output signal that indicates whether the video signal includes an image that is in motion or a still image. The luminance control circuit may be used to vary luminance levels between two or more consecutive frames of the video signal when the motion detection output signal indicates that the video signal includes an image that is in motion. The luminance control circuit further may also be used to discontinue varying the luminance levels of the video signal when the motion detection output signal indicates that the video signal includes a still image.
