ABSTRACT:
In a method, a display device and a computer program product that reduces motion blur, flicker and loss of brightness of images shown in non-stroboscopic display devices, such as Liquid Crystal, Plasma Panel, Thin Film Transistor, Liquid Crystal on Silicon, color Sequential, Organic Light Emitting Diode or Polymer Light Emitting Diodes displays, in which each image of an input video signal is displayed during a display time ti, which is less than or equal to a picture period T, the motion and the characteristics of motion are measured and the display time tiis continuously adjusted between 0 and T depending on this measured motion and the characteristics of motion. To further reduce flicker and loss of brightness encountered when reducing the display time, anti-motion blur filtering of the input video signal is performed, where the display time and the amount and sort of filtering is jointly controlled based on the measured motion and characteristics of motion.
