Abstract
An imaging displacement module including a frame, an optical element, a carrier, a connecting portion and at least a first actuator is provided. The frame has a first opening, and the optical element, the carrier, the connecting portion and the first actuator are all disposed in the first opening. The carrier is capable of carrying the optical element, and the connecting portion connects between the frame and the carrier and capable of generating an elastic torsion around an axis. The first actuator is disposed at a side of the carrier and capable of driving the carrier to vibrate periodically.
