ABSTRACT:
A converter for converting video signals of an interlace format to video signals of a progressive format includes an intra-field converter and an adaptive temporal filter. The intra-field converter intra-field converts a video signal of the interlace format into a video signal of the progressive format. The adaptive temporal filter temporally filters the video signal of the progressive format such that as a degree of image movement in images represented by said video signal of said progressive format increases, a lesser degree of temporal filtering is performed.
