Abstract
In a camera having a displaceable actuator and a diaphragm adjustable between a maximum aperture value and a minimum aperture value responsive to displacement of the actuator, displacement of the actuator is arrested responsive to first, second, and third signals when the diaphragm is adjusted to the desired aperture value. The first signal is representative of the displacement of the actuator. The second signal is representative of the desired aperture value of the diaphragm for correct exposure. The third signal is representative of the difference between the minimum aperture value and the maximum aperture value. Preferably, the first, second, and third signals are applied to a microcomputer which controls the arresting of the actuator displacement.
