Abstract
A camera with a flash light emitting element and a piezoelectric element for actuating a shutter wherein successive rapid photographing is enabled. The camera comprises a single main capacitor, and a first voltage detecting means for detecting a first charged voltage of the capacitor required to drive a piezoelectric actuator element for the shutter of the camera, and a second voltage detecting means for detecting a higher second charged voltage of the capacitor required to drive the piezoelectric element and cause a flash light emitting means to emit light. In response to an output of a light measuring means, the first voltage detecting means is selected when the brightness of the object is higher than a predetermined brightness, and the second voltage detecting means is selected when the brightness of the object is lower than the predetermined brightness.
