Abstract
A novel noise reduction system developed to improve the sensitivity of video cameras is reported. The frequency resolution characteristics, feedback characteristics, and bit accuracies of the noise reduction circuit in which the field or frame difference signal is separated into frequency components were studied for improving the S/N (signal-to-noise ratio) of the color difference signal, and for optimizing its circuit construction. An S/N improvement as high as 9 dB at a permissible lagged image level is thus accomplished, and this is to be used to improve the sensitivity of home video cameras. >
