| 摘要 |
The present invention is related to a method and an apparatus for line-based motion estimation in video image data, especially for field rate up-conversion in consecutive frames/fields of a motion picture, comprising the steps of: providing a video signal comprising video image data of a several video lines or part of these video lines of a frame or a field; performing the motion estimation by line -based detecting and analysing the video image data and by deriving motion vectors depending on the detected motion; wherein the motion estimation employs a matching process for testing and up-dating the different lines within a field or frame and wherein matching process is different for the first line of the frame or field compared to the other lines of the same frame or field. The present invention is further related to TV-set, a computer program product and a data carrier comprising a computer program. |
