Abstract

PURPOSE:To convert an error part to a half tone color and record it without adding a complicated circuit, by dividing the regenerated FM signal to a signal passing through the BPF and a signal not passing through the BPF, and switching to the signal which does not pass through the BPF for a prescribed time after an error signal has been detected. CONSTITUTION:An FM signal is regenerated from the recording medium in which an FM modulation picture signal has been recorded by the optical recording means or the magnetic recording means, and this FM regenerative signal is inputted to the delaying circuit 11 and the error detection circuit 14. Also, the signal which has been inputted to the delaying circuit 11 is divided into two, one is directly provided to the input terminal of the amplifier 13 provided with a gate, also the other is inputted through the BPF12. And, a gate signal for a prescribed time which requires from detecting an error by the detection circuit 14 to attaining to the next horizontal time is generated by the gate generating circuit 15, the amplifier 13 is controlled by said gate signal, it is output by being switched to a signal which does not pass through the BPF12 for said period, the error part is converted to a half tone color, and it is recorded so that the error part does not become an obstacle to the view.
