A video recording system comprising in combination:
- (A) image pick-up means for producing an electrical signal corresponding to a received object image, said pick-up means having a partially operative standby state for preparation of the production of said signal and a fully operative state at which the pick-up means produces the signal;
- (B) recording means for recording the electrical signal produced from said image pick-up means on a recording medium, said recording means having a partially operative standby state for a preparation of the signal recording and a fully operative state at which the recording means records the signal on the medium;
- (C) first instruction means for setting said image pick-up means and said recording means at their respective standby states;
- (D) second instruction means for producing an instruction to set said image pick-up means and said recording means at their respective fully operative states;
- and
- (E) control means for inhibiting the instruction of said second instruction means until said image pick-up means and said recording means reach their respective standby state.
