Abstract: A cost-effective motion-adaptive video processing system was developed for luma/chroma separation and frame recursive noise reduction, using only a 2-Mbit frame memory. The problem of aliasing due to subsampling and the problem of waveform deterioration due to band restriction were solved, and a method of chroma motion detection using interframe difference signals was developed. Therefore, the required frame memory capacity can be reduced without a performance compromise. The video processing part of this system was produced as a single-chip digital LSI and was installed in a home-use S-VHS format VCR. The result was improved picture quality for VCR recording and playback. >
