Abstract:
1. A method for reducing the visibility of false contours in a digitally driven display device, the method comprising: receiving pixel data for a plurality of pixels in a frame to be displayed on the display device; comparing pixel data for one or more pixels in the frame with pixel data for one or more adjacent pixels to determine a number of false contour occurrence locations and a number of true contour occurrence locations for the frame; computing a probability of occurrence of a false contour in the frame based on a ratio between the number of false contour occurrence locations for the frame and the number of true contour occurrence locations for the frame; and generating a plurality of subframes to represent the frame for driving the display device, wherein a number of subframes is set in accordance with the probability of occurrence of a false contour in the frame.
