Abstract: An image capturing unit is provided, including a base, a frame movably connected to the base, a lens holder movably disposed in the frame for receiving a lens, a first magnet, a first coil, a second magnet, and a second coil. When a current is applied to the first coil, a magnetic force is generated between the first magnet and the first coil to move the frame and the lens holder relative to the base. When a current is applied to the second coil, a magnetic force is generated between the second magnet and the second coil to move the lens holder relative to the frame.

Abstract: A lens driving module for holding and moving a lens is provided, including a lens holder having an accommodating space, a driving coil, a plurality of first magnetic members having a longitudinal structure, a virtual plane, and a plurality of second magnetic members, wherein the lens is disposed in the accommodating space. The lens holder is disposed between the first magnetic members and between the second magnetic members. The driving coil is disposed on the lens holder and surrounds the accommodating space. The virtual plane is perpendicular to a longitudinal axis of the longitudinal structure. The projections of the driving coil and the first magnetic members on the virtual plane along the longitudinal axis of the longitudinal structure overlap each other. When a first current flows through the driving coil, the lens holder moves relative to the first and second magnetic members along a first direction.

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.
