Abstract: A camera device is provided, which includes an image sensor and an optical lens arranged corresponding to the image sensor. An axis is defined on the light incident surface of the image sensor. The edge of the optical lens includes a straight segment that is parallel to the axis. Since the non-effective area of the optical lens is decreased, the camera module has a smaller size.

Abstract: A lens driving device includes a base and a frame movably connected to the base. A holder carries a lens and is movably disposed in the frame. A focus driving unit includes at least one first coil disposed on the holder and at least one first magnetic element disposed on the frame and corresponding to the first coil. Electromagnetic induction occurs between the first coil and the first magnetic element, so that the holder is moved along an optical axis of the lens with respect to the base. A tilt driving unit includes several first electromagnetic driving parts disposed on opposite sides of the holder and several second electromagnetic driving parts disposed on the frame and corresponding to the first electromagnetic driving parts. Electromagnetic induction occurs between the first and second electromagnetic driving parts, so that the holder is tilted with respect to the base.
