Abstract:
1. An anti-shake structure for auto-focus module for capturing and focusing light on an image sensor covered by a sensor holder, comprising: an auto-focus module for driving a lens to move forward and rearward in a light entering path, i.e. in z-axis direction, so that the lens focuses the captured light on the image sensor; a frame having a top cover plate formed with a central opening for holding the auto-focus module therein; a lens suspender with at least one compensation lens arranged thereon, the lens suspender being connected to a plurality of suspension wires while the suspension wires are connected at respective one end opposite to the lens suspender to the top cover plate of the frame, so that the compensation lens is correspondingly suspended in the frame in the light entering path and located behind the lens; the lens and the compensation lens moving independently of each other, the lens moving in the z-axis direction and the compensation lens moving in the x-axis direction and the y-axis direction; and a shake compensation driving unit for driving the lens suspender to move horizontally in x-axis direction or y-axis direction, so as to compensate any shift of image caused by hand shaking.
