Title: Reproducing signal processing circuit for video tape recorder
Inventor: NIHEI SATOSHI
IPC: H04N9/793
Filed: 1994-02-07
Abstract: PURPOSE:To reduce the degradation of delay time characteristics due to chroma traps and to improve the quality of reproduced picture, suppressing beat interference and white inversion due to cross modulation distortion. CONSTITUTION:A control voltage generation circuit 22 generates control voltages C1-C4 corresponding to the detection output C0 of a color density detection circuit 19. The depth of trap characteristics is controlled corresponding to the density of colors by the control voltage C1 and a chroma trap circuit 4 extracts frequency modulated luminance signals from the reproducing signals of a magnetic tape 1 well at all times. Peaking characteristics are controlled corresponding to the density of the colors by the control voltage C2 and a peaking circuit 5 balances the upper and lower side band waves of the frequency modulated luminance signals at all times. The trap characteristics for extracting beat frequency components are controlled corresponding to the density of the colors by the control voltage C3 and a noise cancelling circuit 12 effectively removes the components. A picture control circuit 13 compensates the band narrowing of the luminance signals by peaking corresponding to the density of the colors by the control voltage C4.
