Abstract

PURPOSE:To block the appearance of the effect of color noise, by decreasing the gain at the chroma signal processing circuit at weak electric field operating the booster. CONSTITUTION:At a weak electric field district, the booster selector switch 7 to operate the booster 2 is ON. If the noise given from the intermediate frequency circuit 5 to the automatic video tone circuit 10 is more than a given level at weak electric field, the high band frequency components of video signal are attenuated at the video circuit 6 to decrease the gain of the chroma signal processing circuit 8, allowing to cause soft screen not remarkable in noise on the screen of the receiving tube 9.
