PURPOSE:To execute suitably exposure control and focus control also by controlling the moving of a camera by using the signal of one of the plural pictures generated from the same object different in exposure quantity as reference. CONSTITUTION:A sample holding circuit 26 and a switch 29 are provided in order that control signals to control an automatic diaphragm adjusting AE action are limited to only one of the plural images different in exposure quantity. A sampling pulse is formed from a vertical blanking VELK, a 1/2 frequency divider 24 forms such signals as inverting at every VELK signal which are lead to the contact (a) of the switch 29. Also an output from the divider 24 is inverted by an inverter 28 and is lead to the contact (b) of the switch 29. When a switch 22 selects its contact (a), sampling pulses for which odd-field, 1/1000sec accumulating signal made as a reference for AE loop control are impressed to the circuit 26. Inversely, when the contact (b) is selected, pulses for which 1/60sec accumulating signal used as the reference for AE loop control are impressed to the circuit 26.
