A camera module includes a movable portion including a lens barrel, an accommodating portion configured to receive the movable portion, and a driving unit configured to drive the movable portion, comprising a driving magnet integrated with the movable portion. A cross-sectional area of the driving magnet decreases as a distance thereof from an optical axis increases.

An actuator for a camera according to an embodiment includes a base having an inner space formed therein, a carrier provided inside the base and configured to move in at least one direction among an optical axis direction, a first direction perpendicular to the optical axis and a second direction perpendicular to the optical axis and the first direction; and a damper provided to the carrier or the base and configured to have a shape extending in two or more directions among the optical axis direction, the first direction and the second direction.

An optical element driving mechanism is provided. The optical element driving mechanism includes a movable portion, a fixed portion, a driving assembly, and a stopping assembly. The movable portion is used for connecting to an optical element having a main axis. The movable portion is movable relative to the fixed portion. The driving assembly is disposed on the fixed portion or the movable portion to move the movable portion relative to the fixed portion. The stopping assembly connects to the movable portion and the fixed portion to limit the range of motion of the movable portion relative to the fixed portion.

One embodiment of a lens driving apparatus may comprise: a bobbin having a first coil disposed on the outer circumferential surface thereof; a position detection sensor which is disposed on the outer circumferential surface of the bobbin and which moves together with the bobbin; a first magnet disposed opposite to the first coil; a housing for supporting the first magnet; upper and lower elastic members which are coupled to the bobbin and the housing; and a plurality of wirings which are disposed on the outer circumferential surface of the bobbin so as to electrically connect at least one of the upper or lower elastic members with the position detection sensor.

An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion, a fixed portion, a first driving assembly, and a plurality of second guiding members. The first movable portion is configured to connect an optical member. The optical member is used for adjusting a direction of a light from an incident direction to an outgoing direction. The first movable portion can move relative to the fixed portion. The first driving assembly is configured to drive the first movable portion to move relative to the fixed portion. The second guiding members include a first ball, a second ball, and a third ball. The first ball, the second ball, and the third ball are disposed in a plane that is perpendicular to the incident direction.

A coil substrate according to an embodiment includes an insulating layer; a first coil pattern portion disposed on one surface of the insulating layer; a second coil pattern portion disposed on the other surface of the insulating layer; and a pad portion disposed on the one surface of the insulating layer and connected to the first coil pattern portion, wherein the first coil pattern portion includes: an inner coil pattern portion; and an outer coil pattern portion spaced apart from the inner coil pattern portion at a predetermined interval and disposed outside the inner coil pattern portion, wherein the pad portion is disposed between the inner coil pattern portion and the outer coil pattern portion.

A photosensitive element driving mechanism is provided and includes a fixed assembly, a first movable assembly, a photosensitive element and a first driving assembly. The fixed assembly has a base plate. The first movable assembly includes a circuit member movable relative to the fixed assembly, and the circuit member includes a circuit member body and a movable cantilever. The photosensitive element is configured to receive light traveling along an optical axis. The photosensitive element is disposed on the circuit member body and is electrically connected to the circuit member. The first driving assembly is configured to drive the first movable assembly to move relative to the fixed assembly. There is a gap between the first movable assembly and the fixed assembly, and only the photosensitive element is disposed on the circuit member body.

A camera assembly comprises a lens assembly supported on a support structure, wherein the lens assembly includes an autofocus actuator arrangement and the camera assembly includes an optical image stabilization assembly arranged to move the lens assembly in a plane perpendicular to the optical axis. A flexible printed circuit tape connected between the support structure and the lens assembly and providing an electrical connection to the auto-focus actuator arrangement is bent around a corner, thereby allowing the flexible printed circuit tape to accommodate the motion of the lens assembly perpendicular to the optical axis. A crimp plate connected to the lens assembly which crimps shape memory alloy wires has features extending out of the plane of the crimp plate for reducing flexibility. At least part of the optical image stabilization assembly overlaps the lens assembly in the direction along the optical axis, thereby reducing the height of the camera assembly.

An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a movable portion, and a driving assembly. The movable portion is movably connected to fixed portion, wherein the movable portion is used for connecting to an optical element having a main axis. The driving assembly is disposed on the fixed portion or the movable portion to move the movable portion relative to the fixed portion.

A lens apparatus includes an urging member disposed between first and second lens holding members, a first guide member including a first receiver configured to receive the urging member, and a first guide protrusion extending in an optical axis direction from the first receiver toward the second lens holding member, and a second guide member including a second receiver configured to receive the urging member; and a second guide protrusion extending in the optical axis direction from the second receiver toward the first lens holding member. The first and second guide protrusions have areas that always overlap each other in the optical axis direction in a use state. When the first and second lens holding members are closer to each other than a predetermined state, at least part of the first and second guide protrusions protrudes from the first or second receiver.
