Abstract
An image displacement module includes a base, a carrier, an optical element, a freely rotating shaft, a flexible shaft, and at least one actuator. The optical element is disposed on the carrier. The freely rotating shaft and the flexible shaft are in a same axis and located between the base and the carrier. The flexible shaft is capable of acting a force on the carrier along the axis, and the carrier is capable of moving along the freely rotating shaft relative to the base to release the force. The actuator is disposed between the base and the carrier. When the actuator drives the carrier to rotate in the axis relative to the base, the flexible shaft generates an elastic torsion. When the actuator does not drive the carrier to rotate in the axis relative to the base, the flexible shaft drives the carrier to reposition relative to the base.
