Claim One:
1. A method to reduce motion blur of images shown in a non-stroboscopic display device, the method comprising the acts of: calculating motion vectors depending on moving components in each image of an input video signal; determining edge characteristics in each image of the input video signal, wherein said edge characteristics are length of an edge and/or orientation of edge vectors; performing anti-motion blur filtering of the input video signal based on the calculated motion vectors and said determined edge characteristics to produce an output video signal; generating images on said display device depending on said output video signal, wherein the act of performing the anti-motion blur filtering comprises acts of: filtering the input video signal with a spatial filter; and subsequently combining the filtered input video signal with the input video signal itself to produce an intermediate video signal, wherein the act of combining comprises acts of: multiplying the intermediate video signal with gain factors to produce an amplified intermediate signal, and combining said amplified intermediate signal with said input video signal to produce said output video signal, wherein the spatial filter applied to the input video signal is a high spatial frequency boosting filter, and wherein filter coefficients of the high spatial frequency boosting filter and a direction of a frequency characteristic of the filter depend on the motion vectors, and wherein the gain factors depend on an inner product of edge vectors and motion on vectors normalized to the length of the edge vectors.
