Title: Noise decreasing circuit
Inventor: ITAMI TERUO
IPC: G11B20/02
Filed: 1985-07-01
Abstract: PURPOSE:To improve picture quality without spoiling the detailed expression by changing the quantity of a limiter functioning to noise components which are extracted from a reproducing liminance signal in accordance with the noise level contained in the reproducing luminance signal. CONSTITUTION:HPF 1 extracts high area components of both noises and signals from reproducing Y signals 100, from which a subtraction circuit 3 subtracts the noise components being input from a limiter 2 and then outputs the reproducing Y signals 200, from which the noise components have decreased. Gate circuits 4 allow the reproducing Y signals 100 to pass only a blanking interval by blanking signals 300 and the HPF 5 extracts only noise components from signals of the blanking interval. A detector 6 converts the noise components into direct current levels corresponding to their levels and the limiter 2 makes the limiters increase or decrease through direct current levels given by a DC amplifier 7. Since components subtracted from the reproducing Y signal 100 by an adder 3 remain only noise component minute signal components of the reproducing Y signal 100 to be lost are decreased.
