Abstract

Motion between adjacent fields of an interlaced video signal is analysed by vertically interpolating the current field to produce a line signal which corresponds in vertical position with lines from the succeeding and preceding fields; and subtracting the signals to provide a field difference. A measure of detail is taken at each pixel and the field difference signal weighted through multiplication by said detail measure. Noise in the field difference signal is therefore reduced through a reduction in the contribution from plain areas.
