Patent

CA 2146884

A method for processing video data to produce a progressively scanned signal from an input of conventional interlaced video. The data is received at a processor (1), used to determine a motion signal (26) over time between field of the data. The motion signal is filtered to reduce errors caused by noise-corrupted video sources and then further filtered to spread out the determined motion signal. Edge information (30) is located and combined with the motion signal to produce an integrated progressive-scan signal (36) for display on a video display device, producing images with sharper edges and motion signals which have a lower susceptibility to noise.
