摘要： The invention relates to a method and a circuit arrangement to reduce motion blur of images shown in non-stroboscopic display devices, in particular Liquid Crystal Display Panels (LCDs). Thin Film Transistor Displays (TFTs), Color Sequential Displays. Plasma Display Panels (PDPs), Digital Micro Mirror Devices or Organic Light-Emitting Diode (OLED) displays, in which motion vectors depending on moving components in each image of an input video, signal are calculated, in which anti-motion blur filtering of the input video signal is performed based on the calculated motion vectors to produce an output video signal, and in which images are generated on said display device depending on said output video signal. In order to provide an improved spatial filtering with less noise enhancement and less noise modulation, it is proposed that edge characteristics in each image of the input video signal are determined and that anti-motion blur filtering is further based on said determined edge characteristics. In this way, spatial filtering is concentrated on significant parts of an image only, and both noise enhancement and noise modulation are reduced.
