METHODS AND APPARATUS FOR PROGRESSIVE SCANNING OF INTERLACED VIDEO

摘要

A method for deinterlacing an interlaced video signal is provided which employs a median single edge based line average field interpolation algorithm. The algorithm employs a median filter to determine whether motion occurred between scanning two fields of an interlaced frame and, based on the results, reconstructing intermediate lines in the display frame. The median performs a median computation by determining whether a target pixel value is a median value, rather than computing the median value and determining whether the target pixel value is equal to the computed median.
