ABSTRACT:
An automatic centering method for a video camera having a plurality of pick-up tubes and a deflection control circuit for each of the plurality of pick-up tubes is disclosed, which includes the steps of comparing outputs of two pick-up tubes of the plurality of pick-up tubes to thereby generate an error signal, processing the error signal to thereby generate a control signal, supplying the control signal to the deflection control circuit for one of the two pick-up tubes, storing the control signal in a memory, changing the control signal supplied to the deflection control circuit by a predetermined amount, repeating the above-described first to third steps, comparing the control signal generated in the sixth step and the control signal in the memory with each other to thereby generate an error flag signal when the above two control signals do not coincide with each other and indicating the error flag signal.
