Abstract: An image detection module comprises a base, a seat movably disposed on the base, an image detection unit on the seat, a first guide member by which the seat is joined to the base, moving relative to the base, a first coil on either the base or the seat, a first magnet on either the base or the seat and opposite to the first coil, a first auxiliary magnet on either the base or the seat, corresponding to the first magnet and the first coil between the first magnet an the first auxiliary magnet, and a first Hall element on either the base or the seat and adjacent to the first coil. A magnetic force is generated between the first coil, the first magnet and the first auxiliary magnet by a voltage provided to the first coil, moving the seat along the first axis along the first guide element.

Abstract: A lens barrel assembly includes a first lens barrel and a second lens barrel. The first lens barrel includes a peripheral wall having a first end portion, a second end portion opposite to the first end portion, and a plurality of cam slots extending between the first end portion and the second end portion. Each of the cam slots defines two opposite guiding walls. The second lens barrel is disposed slidably in the first lens barrel, and includes an annular body, and a plurality of cam followers mounted on the annular body and extending through the cam slots, respectively. Each of the cam followers has a shank portion, a head portion, and a rolling member disposed around the shank portion and stopped by the head portion. The rolling member has a spherical outer surface for contacting the guiding walls of one of the cam slots.
