Abstract

PURPOSE:To coincide the relative position between an objective image and electronic beam scanning at each pickup tube, by adjusting the phase of an output signal of two pickup tubes with an output acquired by sample-holding the signal difference of both output signals. CONSTITUTION:An output green signal G of a pickup tube 1G is applied to a delay circuit 3 to be a signal G1 delayed by 1H and applied to a subtraction circuit 12. An output red signal R of a pickup tube 1R is applied to the circuit 12, and an output signal G1-R of the circuit 12 is applied to sample hold circuits 13 and 14. Further, the signal G1 is applied to a delay circuit 4 to be a signal G2 delayed by 1H and given to a subtraction circuit 5 where a difference signal G-G2 is obtained. the signal G-G2 is applied to voltage comparison circuits 6 and 7 to obtain signals P6 and P7 indicating the edge of objective image. The signals P6 and P7 sample-holds the signal G1-R given to the circuits 13 and 14 as a control signal, and outputs V3 and V4 of the circuits 13 and 14 are applied to a voltage comparison circuit 15. The value in quantity of the voltages V3 and V4 controls the scanning position of electronic beam of the pickup tube 1R.
