Abstract
PURPOSE: To make desired setting of automatic aperture easy by displaying the arrival of the subject light at the upper limit set level or more or lower limit set level or lower and making the same as a measure for the reference signal set time of an automatic aperture driving circuit.
CONSTITUTION: When the subject light through a lens 2 with automatic aperture mechanism is detected by an image pickup element 5, a control signal generating circut 6 applies the one of the control signals corresponding to the subject light to an automatic aperture mechanism driving circuit 7 and the other to +, - display lamp driving circuits 10, 11. When the regulator 8 which sets the reference signal is adjusted in one direction, the reference signal for comparison to be set in the circuit 7 changes and the quantity of light received in the element 4 through the aperture changes and therefore, the + or - display lamp 16 or 19 is lighted by way of the circuit 10 or 11 through the comparison with the specified upper or lower reference signal. If with this constitution the regulator 8 is operated with the putting-out of the display lamps 16, 19 as a measure, the desired setting of the automatic aperture may be done with ease.
