ABSTRACT:
An electronic camera with a vidicon tube, comprising a synchronization generator consisting of a frequency divider receiving the frequency of a quartz oscillator (Q.sub.1) and supplying, by combination, the various synchronization signals, in which the synchronization generator piloted by the quartz oscillator (Q.sub.1) consists of a first stage comprising the quartz oscillator (Q.sub.1) energizing two gates (NAND 1,2), to provide an output frequency successively divided by dividing circuits (CI.sub.1, 2, 3, 4), furnishing the respective signals to a combining stage M, combining the various signs (S.sub.1 -S.sub.5), and supplying the synchronization and scanning signals, the protection signals, the mixer signals and if necessary the reference signal of the high frequency generator (15).
