Patent number: 8218016Abstract: Disclosed herein is an image stabilization mechanism for a camera module. The image stabilization mechanism includes a base, a movable stage receiving a lens barrel therein and having a magnet, and a piezoelectric actuator. The piezoelectric actuator is installed to the base, moves the movable stage in an X-axis or Y-axis direction to remove shake of the lens barrel, and maintains contact with the movable stage because of magnetic attractive force between the piezoelectric actuator and the magnet. The image stabilization mechanism reduces the number of components, thus simplifying the structure and minimizing an increase in height.Type: GrantFiled: December 23, 2009Date of Patent: July 10, 2012Assignee: Samsung Electro-Mechanics Co., LtdInventors: Chuel Jin Park, Chul Yeub Han, Soo Cheol Lim, Jae Hyuk Park, Dong Kyun Lee
