Abstract: A camera module includes an imaging lens having an optical axis, a variable through hole mechanism, an image sensor, an image sensor actuating module and a flexible printed circuit. The variable through hole mechanism is disposed corresponding to the imaging lens to adjust an amount of light into the imaging lens. The image sensor is disposed on the optical axis and is configured to convert imaging light passing through the imaging lens into an image signal. The image sensor actuating module is configured to move the image sensor. The variable through hole mechanism and the image sensor actuating module each have a coil disposed on the flexible printed circuit. The flexible printed circuit is electrically connected to the variable through hole mechanism and the image sensor actuating module.

Abstract: A lens driving apparatus includes a holder, a cover, a carrier, a first magnet, a coil, a spring, two second magnets and a hall sensor. The holder includes an opening hole. The cover is made of metal material and coupled to the holder. The carrier is movably disposed in the cover, and for coupling to a lens. The first magnet is connected to an inner side of the cover. The coil is wound around an outer side of the carrier, and adjacent to the first magnet. The spring is coupled to the carrier. The second magnets are disposed on one end of the carrier which is toward the holder. The hall sensor is for detecting a magnetic field of any one of the second magnets, wherein the magnetic field is varied according to a relative displacement between the hall sensor and the second magnet which is detected.

Abstract: A camera module includes a fixed base, a movable carrier disposed on the fixed base, a guiding element disposed between the fixed base and the movable carrier and providing a degree of freedom of movement of the movable carrier relative to the fixed base, a lens system fixed to the movable carrier, an image sensor configured to receive an optical image signal from the lens system, an auto focus driving device configured to provide a driving force for auto focusing of the lens system, and an image stabilization driving device configured to provide a driving force for image stabilization of the image sensor. The fixed base and the movable carrier each has a guiding structure. The guiding structures correspond to each other and are in contact with the guiding element. Therefore, the movable carrier is movable in a direction parallel to an optical axis of the lens system.
