摘要: 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.

摘要: An apparatus has a member to be driven, an actuator for driving the member, a position detector and a controller. The actuator drives the member to move by an amount proportional to a given number of pulses. The position detector detects a position of the member in predetermined detection steps. The controller determines in steps smaller than the predetermined detection steps a target position up to which the member is to be moved. Then, it controls the actuator up to a detection-step position before the target position by closed-loop control in accordance with a detection result from the detector. Further, it controls the actuator from the detection step position to the target position by open-loop control.
