Research output: PatentPatent publication


The invention relates to a method for providing a motion parameter set and/or a picture repetition pattern from an input video signal, in particular for de-interlacing a video signal with using a candidate motion parameter set weighted with a picture repetition pattern value for calculating a motion compensated pixel from a pixel value of a first image. To provide motion compensation which accounts for field repetition patterns, minimizing an error criterion between at least one pixel value of a second image and at least the motion compensated pixel value by iterating the calculation of the motion compensated pixel with at least two candidate motion parameters sets and/or at least two picture repetition values, and putting out the candidate motion parameter set and/or the picture repetition value which provides the minimized error criterion is proposed.
