Title: Noise decreasing circuit
Inventor: KITA HIROYUKI
IPC: H04N5/93
Filed: 1987-10-08
Abstract: PURPOSE:To automatically turn on/off a noise decreasing circuit according to noise decreasing effect by detecting whether or not the number of horizontal synchronization pulses in one field is within a prescribed range, and turning on/off the noise decreasing circuit with the use of the detecting signal. CONSTITUTION:Whether or not the number of pulses synchronized with the horizontal synchronization signal in one field period of a regenerative video signal is within the prescribed range is detected by detecting means 28 and 29. When the number of the pulses synchronized with the horizontal synchronization signal in one field period is outside of the prescribed range, a noise decreasing means 36 is turned off by a noise decreasing on/off switch 9, and when the number of the pulses synchronized with the horizontal synchronization signal in one field is inside of the prescribed range, th noise decreasing means 36 is turned on by the on/off switch 9. Thus, the on/off operation of the noise decreasing circuit is automatically attained according to the noise decreasing effect.
