1. Method for motion-vector-based conversion of a first video signal which contains a first image sequence (A 1, B 1, A 2, B 2, A 3, B 3,... ) at a first frequency (f org ) to a second video signal which contains a second image sequence (&agr; 1, &bgr; 1, &ggr; 1, &dgr; 1, &egr; 1, &xgr; 1,... ) at a second frequency (f int ), wherein at least some images from the second image sequence (&agr; 1, &bgr; 1, &ggr; 1, &dgr; 1, &egr; 1, &xgr; 1,... ) which are phase-shifted relative to images from the first image sequence (A 1, B 1, A 2, B 2, A 3, B 3,... ) are generated by an interpolation of the images from the first image sequence (A 1, B 1, A 2, B 2, A 3, B 3,... ) such that for a pixel of an image (&xgr; 1 ) from the second image sequence (&agr; 1, &bgr; 1, &ggr; 1, &dgr; 1, &egr; 1, &xgr; 1,... ), pixels at least from one first image (A 3 ) and one second image (B3) from the first image sequence (A 1, B 3, A 2, B 2, A 3, B 3,... ) are filtered by a median filter, characterized in that the median filter is an adaptively weighted median filter.
