Title: Chroma signal processing circuit for video tape recorder
Inventor: KANEKO MASAYASU
IPC: H04N9/87
Filed: 1995-03-24
Abstract: PURPOSE: To obtain a chroma signal processing circuit which improves dullness of the waveform in the vicinity of a noncorrelation part of a chroma signal and has a high S/N improvement effect by subjecting the non-correlation part of the reproduced chroma signal to amplitude limiting processing and feeding it back. CONSTITUTION: When the reproduced chroma signal outputted from a first comb line filter 10 is inputted to an adder 22 of a second comb line filter 20 through a 18 delay line 23, this adder 22 extracts and outputs the non-correlation part and the noise component of the signal from the output of an adder 21. A limiter 24 subjects the non-correlation part or the output of the adder 22 to amplitude limiting processing, and an attenuator 25 attenuates the output of the limiter 24 and feeds it back. By this constitution, the noise component of the reproduced chroma signal is attenuated to the original amplitude by the attenuator 25, and the non-correlation part has the same small amplitude as the noise component by the limiter 24.  Consequently, dullness of the waveform in the vicinity of the non-correlation part is improved to prevent color slurring and color blot, and a high S/N improvement effect is obtained.
