The invention discloses a three-piece optical lens for capturing image and a three-piece optical module for capturing image. In order from an object side to an image side, the optical lens along the optical axis comprises a first lens with positive refractive power; a second lens with refractive power; and a third lens with refractive power; and at least one of the image-side surface and object-side surface of each of the three lens elements are aspheric. The optical lens can increase aperture value and improve the imaging quality for use in compact cameras.

A device is provided. The device includes a first lens assembly controllable to switch between a first plurality of optical powers. The first lens assembly includes a plurality of directly optically coupled lenses, and is configured to converge or diverge a light transmitted therethrough. The device also includes a second lens assembly coupled with the first lens assembly, and controllable to switch between a second plurality of optical powers that are opposite to the first plurality of optical powers.

The proposed invention relates to a camera module with an optical image stabilization function. A flexible printed circuit board (FPCB) electrically connected to an image sensor is implemented to serve as an electrical path and at the same time, serve to provide an elastic restoring force in directions of a plurality of axes, thereby further miniaturizing and lightening the camera module.

A lens barrel having one end and the other end includes: a first frame that is movable and holds optical members; a second frame that is arranged to be relatively movable toward the other end with respect to the first frame, and holds optical members; and a third frame that is mounted on the first frame so as to be movable, and holds an optical member. The first frame includes a first stopper portion that comes into contact with the third frame to limit movement toward the one end. The first frame includes a second stopper portion that comes into contact with, when the first frame is most distant from the second frame, the third frame to limit movement toward the other end. The second frame includes a third stopper portion that has a contact surface located close to the one end with respect to the second stopper portion, and that comes into contact with, when the second frame is located within a range on the optical axis where the third frame is movable, the third frame to limit movement toward the other end.
