Various embodiments include a camera with folded optics and lens shifting capabilities. In some examples, a folded optics arrangement of the camera may include one or more lens elements and one or more light path folding elements (e.g., a prism). Some embodiments include voice coil motor (VCM) actuator arrangements, carrier arrangements, and/or suspension arrangements to provide autofocus (AF) and/or optical image stabilization (OIS) movement. Furthermore, some embodiments include position sensor arrangements for position sensing with respect to AF and/or OIS movement.

A camera module includes a base, a lens module, a reflection module, a longitudinal guiding bar, a transverse guiding bar and a shaft guiding bar. The lens module has an optical axis and is disposed on the base. The reflection module includes a reflective element disposed on the base and located on an object side of the lens module. The longitudinal and transverse guiding bars are disposed between the base and the lens module and respectively extend in a first direction parallel to the optical axis and a second direction perpendicular to the optical axis. The shaft guiding bar is disposed between the base and the reflection module and extends in the second direction. The lens module is movable along the longitudinal and transverse guiding bars, respectively, and the reflective element is rotatable by taking the shaft guiding bar as a rotation axis.

A lens drive device is provided with: a lens holder for holding a lens; an ultrasonic motor configured to move the lens holder in a direction of an optical axis; and a support part configured to support the lens holder in a state where the lens holder is urged in a direction orthogonal to the optical axis and such that the lens holder is capable of moving in the direction of the optical axis. The support part includes two pairs of support portions which are disposed respectively on two straight lines along an urging direction and parallel to each other such that the support portions of each pair holds the lend holder therebetween.

A camera module is provided. The camera module includes a carrier; a lens holder accommodated in the carrier; an optical image stabilization (OIS) cover coupled to the carrier and disposed on the lens holder; and first buffer members coupled to the OIS cover, wherein a distance between the lens holder and the first buffer member is less than a distance between the lens holder and the OIS cover.

An image stabilization apparatus includes a fixing member, a movable member, a guiding member movable in a first direction orthogonal to the optical axis relative to the fixed member, and configured to guide the movable member while restricting a rotation of the movable member on the plane orthogonal to the optical axis relative to the fixed member, and a rolling member rollably held between the fixed member and the guiding member. The fixing member includes a first groove extending in the first direction and contacts the rolling member. The guiding member includes a second groove that extends in the first direction and contacts the rolling member. The rolling member can contact an end of the first groove and an end of the second groove while the guiding member is located at one of ends in a movable range of the guiding member in the first direction.

A camera module includes: a housing; a carrier accommodated in the housing, and configured to move in an optical axis direction; a lens unit accommodated in the carrier, and configured to move in the optical axis direction together with the carrier; a driving unit configured to move the carrier; and a guide unit configured to guide the movement of the carrier, and comprising: a ball member configured to move in the optical axis direction; and a guide groove unit comprising a plurality of guide grooves in which the ball member is disposed, wherein the plurality of guide grooves comprise a first guide groove in which an angle between normals of two adjacent surfaces of the first guide groove in contact with the ball member is an acute angle.

A lens drive device comprises: a fixing part disposed away from the movable part; a cover for covering the movable part in the direction of an optical axis; and suspension wires for supporting the movable part relative to the fixing part, one ends of the suspension wires being secured to the fixing part and the other ends being secured to the movable part. The movable part is configured so as to be provided with: a damper material disposed so as to come in contact with the suspension wires; a stopper protrusion provided near a portion of the light-receiving-side surface where the other ends of the suspension wires are secured, the tip end of the stopper protrusion facing the inner surface of the cover in the direction of the optical axis; and a flow-stopper part stopping a flow of the damper flowing.

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.
