Abstract
A signal is generated which is active only during an interval of taking one pulse of a series of output pulses of said synchronization detecting sensor, but is not active during an interval of taking more than one pulse thereof. Then, synchronization detection pulses are separated from the pulses output by the synchronization detecting sensor for the respective colors by using the thus-generated signal.
