Abstract: PURPOSE:To decrease deterioration in reproduced image quality due to unerased component of a color signal by switching the color killer sensitivity at record and reproduction to improve the color killer sensitivity at reproduction. CONSTITUTION:A video signal inputted to a point A is fed to a BPF 4 via an REC/PB switch and applied to a video head E via an ACC amplifier 5, the REC/PB switch and a frequency converter 12 or the like. A reproduced signal obtained by the video head 4 is given to an LPF 1, the REC/PB 3, 6 and an amplifier 10 or the like and a video signal is outputted at an output terminal D. Through the constitution above, the amplifier 10 is controlled by a color killer detection output voltage 8 and a PB voltage (a voltage generated only at reproduction) inputted to a point C to improve the killer sensitivity. No color signal is outputted form the unerased color signal component generated in dubbing a black-and-white signal by increasing the color killer sensitivity at reproduction in this way.
