Abstract

PURPOSE:To realize the improvement of an S/N when the quantity of reflected light from an object is little by controlling the respective controlled limitters of a luminance signal comb line circuit and noise canceller circuit according to the detection output of a reproduced luminance signal. CONSTITUTION:The reproduced luminance signal outputted by the noise canceller circuit 26 is detected and a limitter control circuit 31 controlling the respective controlled limitters 22 and 25 of the luminance signal comb line circuit 23 and the noise canceller circuit 26 according to the detection output is provided. Therefore, when a video tape recorded with an image of which quantity of the reflected light from the object is little is reproduced, the limitter level of the circuit 23 and the circuit 26 can be lowered. Thus a reproduced picture having the S/N and detailed information of video signal which are almost satisfactory can be obtained.
