Patent attributes
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 metal element on either the base or the seat, corresponding to the first magnet and the first coil between the first magnet an the first metal element, 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 metal element by a voltage provided to the first coil, moving the seat along the first axis along the first guide element.
