To accurately control exposure by setting a specified actuating position in the middle of the movable range of a shutter blade as a reference point and starting measuring time by a timer from this point.
Exposure processing is executed when a release switch is turned on. In this exposure processing, after correction processing concerning a shutter and processing for confirming the initial position of the shutter are executed, the shutter is opened and the exposure is performed. In the case of making a stroboscope emit light, the stroboscope emits the light in timing t4' when the time TFM of the FM timer elapses from reference timing t4 based on the time of the FM timer. The time TFM is decided in accordance with a diaphragm value Av decided based on a subject distance. By setting the timing t4' being in the middle position between the totally closed position t4 and the totally opened position of the shutter, that is, timing after outputting plural AE pulses as the reference timing for starting measuring the time of each timer, the normal rotation of the AE motor is detected.
