置。[Claims for Utility Model Registration] An image reproducing device for reproducing a recording medium in which a luminance signal is FM-recorded using a normal recording method or a high-band recording method, comprising: a head for extracting an FM luminance signal from the recording medium; an FM demodulator that demodulates the FM luminance signal obtained from the head; a level detection circuit that detects the level of a synchronization signal in the output signal of the FM demodulator; and a level detection circuit that detects the synchronization signal based on the output of the level detection circuit. The F is maintained at a predetermined constant level.
An image reproducing device comprising: a level setting circuit for adjusting the output of an M demodulator; and a single de-emphasis circuit to which an output signal of the level setting circuit is supplied.
