    摘要: A method, a circuit arrangement and a display device which suppresses motion blur due to motion integration carried out along a motion trajectory on the image data, which occurs in matrix type displays in which a motion trajectory is integrated by the viewer and/or the display, includes an inverse integration filtering of the video signal. To avoid de-blurring in image regions where motion cannot be detected, or image is low and to avoid noise modulation, motion estimation as well as further image characteristic are used.

    摘要: In a method of processing input fields (I) of a picture signal to obtain interpolated fields (O) located temporally between the input fields (I), motion vectors (MV) are provided (30) between input fields (I), whereafter a quality (Err) of the motion vectors (MV) is assessed (40). In dependence upon the assessed quality (Err), the motion vectors (MV) are adapted (50, 60) such that both decreased and increased motion vector lengths occur in respective interpolated fields (O). The interpolated fields (O) are obtained (20) from the input fields (I) in dependence upon the thus adapted motion vectors (k*MV).
