Abstract: Disclosed herein is a lens actuating module. The module includes a housing having an accommodating space and a bush guide. A lens barrel is accommodated in the accommodating space and includes a lens and a barrel hook. A driving unit applies a driving force to a bush such that it is moved up in the direction of the optical axis, by pulling force of contraction of a shape memory alloy wire. The bush is guided by the bush guide and engages with the barrel hook. A rotary member is interposed between the housing and the lens barrel. A preload unit pulls the lens barrel in the direction of the optical axis such that the lens barrel moves down to an original position, and pulls the lens barrel in a direction perpendicular to the optical axis to maintain a contact of the lens barrel with the rotary member.

Abstract: 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.
