Abstract
A reflection module capable of image stabilization includes a reflecting element, a rotatable holder, a fixed base, a spherical supporting structure, an auxiliary supporting structure and an image stabilizing actuator. The reflecting element having a reflecting surface for folding optical path of incident light is disposed on the rotatable holder. The fixed base is connected to the rotatable holder via an elastic element. The spherical supporting structure is disposed between the rotatable holder and the fixed base. The auxiliary supporting structure disposed on at least one of the rotatable holder and the fixed base and corresponds to the spherical supporting structure. At least part of the image stabilizing actuator is disposed on the rotatable holder for driving the rotatable holder to rotate by taking the spherical supporting structure as rotation center. The spherical supporting structure is a ball having at least three contact points with the auxiliary supporting structure.
