ABSTRACT:
In a flash light amount control device capable of operating according to multiple methods, the flash light control method alternates according to the detected AF mode setting, the camera panning status, or the reliability of the detected object distance. For example, if AF lock is on, control is performed by flash light adjustment, but if AF lock is not on, control is performed by flashmatic. If panning is performed after AF lock, the method of control alternates between flash light adjustment and flashmatic in response to the amount of panning movement.
