Title: Synchronization separating circuit
Inventor: KAMATA TOSHIO
IPC: H04N5/08
Filed: 1991-09-02
Abstract: PURPOSE:To execute correct synchronization separation irrespective of a noise by clamping a composite video signal at prescribed voltage, and cutting off the upper side part of this signal. CONSTITUTION:A component over an average level not relevant to the synchronizing separation in the composite video signal is cut off by a limiter 5, and the composite video signal is inputted to an operational amplifier 10. The operational amplifier 10 and resistors R1 to R3 constitute an inverting amplifier, and the composite video signal whose phase is inverted on the basis of the voltage inputted to a non-inverted input terminal is outputted from the output terminal of the operational amplifier 10. This composite video signal is inputted to the inverted input terminal of a comparator 12 and the inverted input terminal of the operational amplifier 11. The operational amplifier 11, diodes D2, D3 and the resistor R7 constitute a half-wave rectifier, and its output is inputted to the no-inverted input terminal of the operational amplifier 10. Then, the comparator 12 outputs LOW when the voltage of the inputted signal is higher than reference voltage, and outputs HIGH when it is lower, and thus, a synchronizing signal is separated.

Title: Fading function circuit
Inventor: KYO MASAAKI
IPC: H04N5/262
Filed: 1988-09-08
Abstract: PURPOSE:To accurately perform fading to a desired color picture by detecting, for example, the clamp voltage level of a color difference signal, and setting the level of the color difference signal after the fading by adding a prescribed value on a clamped level. CONSTITUTION:At a fading function circuit when fade-out is performed, the value of K(0<=K<=1) in the coefficient K of a coefficient multiplier 3 and the coefficient 1-K of a coefficient multiplier 9 is reduced at every field. Thereby, a finally desired color difference (R-Y) signal can be obtained. As for the color difference signal (B-Y), a desired (B-Y) signal can be obtained similarly. The fade-out to the desired color picture can be performed by performing the balancing modulation of chrominance subcarriers whose phases are different by 90 deg. by the obtained (R-Y) signal and (B-Y) signal. Therefore, it is possible to relax the adjusting accuracy of the clamp level and to accurately perform fading to the desired color picture.
