Abstract:
1. A method for reducing motion blur in a video image displayed on a video display, the method comprising: receiving a video signal that includes a plurality of frames associated with the video image to be displayed on the video display, each of the plurality of frames having a luminance level; comparing the plurality of frames of the video signal to detect motion in the video image, wherein comparing the plurality of frames of the video signal to detect motion in the video image includes varying the luminance levels between two or more consecutive frames of the video image in order to reduce motion blur in the video image, wherein varying the luminance levels between two or more consecutive frames of the video image comprises where D out,n is an output luminance value for a frame n, D in,n is an input luminance value for the frame n, C(m) is the gain coefficient that varies in a stepwise manner with time, and Δ(d) is a luminance correction value from a lookup table that varies based on whether the frame n is an even-numbered frame or an odd-numbered frame.
