A synchronizing signal separation device separates a synchronizing signal from an input signal which includes the synchronizing signal. The device includes a peak clamp circuit for receiving and peak-clamping the input signal, and a pulse clamp circuit for pulse-clamping the input signal. The device is configured so as to separate the synchronizing signal from the input signal by comparing the signal clamped by any of the peak clamp circuit and the pulse clamp circuit with a predetermined level. It is thereby possible to separate an exact synchronizing signal without being influenced by deterioration of the waveform of the input signal.
