An optical unit with an image stabilization function includes a movable body having an annular holder for holding a camera module, a swing support mechanism for swingably supporting the movable body, and a fixing body for supporting the movable body with the swing support mechanism interposed between them. The holder includes three or more of a plurality of protrusions that project radially. The fixing body includes a plurality of arc surfaces that come into contact with each of the plurality of protrusions from the outer peripheral side. The swing support mechanism includes the plurality of protrusions and the plurality of arc surfaces. The arc surface is a concave curved surface obtained by transferring part of a virtual spherical surface centered on a preset swing center point.

The present invention controls against size increase of an optical module drive device. An optical module drive device has: a first swing member configured to hold an optical module; a second swing member connected to the first swing member such that the first swing member is swingable about a first swing axis that intersects the optical axis direction; a fixed member connected to the second swing member such that the second swing member is swingable about a second swing axis that intersects the optical axis direction and is perpendicular to the axial direction of the first swing axis; and a drive part configured to make the first swing member swing relative to the fixed member such that the optical axis tilts. The drive part includes a plurality of shape memory alloy wires provided between movable members including the first swing member and the second swing member, and the fixed member.

The present invention provides a lens driving device and an electronic device, wherein the lens driving device comprises a housing and a lens assembly; the lens assembly includes a lens module and a shell for accommodating the lens module; a bottom wall of the housing is formed an arc-shaped rail; the lens driving device further includes a ball disposed between the housing and the shell and located in the arc-shaped rail; a first driving structure for driving the lens assembly to rotate around an optical axis is further arranged between the housing and the shell; and the first driving structure includes a magnet and a coil opposite to the magnet. The present invention realizes rotation of the lens module around the optical axis direction, thus avoiding the swaying of the lens driving device caused by hand movement, achieving image stabilization, and improving the imaging effect of the lens module.

A camera module includes a housing, a lens module accommodated in the housing, a first optical image stabilization (OIS) driving unit configured to move the lens module, relative to the housing, in a first direction perpendicular to an optical axis direction, and a second OIS driving unit configured to move the lens module, relative to the housing, in a second direction perpendicular to the optical axis direction and intersecting the first direction, wherein the first OIS driving unit includes first voice coil motors disposed on both sides of the lens module in the first direction, and the second OIS driving unit includes second voice coil motors disposed on both sides of the lens module in the first direction.

A thin-plate-typed rotating module includes a rotating element, a driving unit and a base board. The rotating element is rotatable about a first axial direction and a second axial direction in a limited degree. The driving unit connects the rotating element for driving the rotating element to rotate about the first and second axial directions. The base board is furnished with a control module which is connected with the driving unit for controlling the driving unit to operate.

An imaging apparatus comprises two actuators, such as an autofocus actuator and optical image stabilizer. The actuators are nested, wherein the outer actuator is suspended from the device body and the inner actuator is suspended from the outer actuator. A suspension element may be a flexure bearing, allowing a flat actuator design.

A folded camera that includes two light folding elements such as prisms and an independent lens system, located between the two prisms, which includes an aperture stop and a lens stack. The lens system may be moved on one or more axes independently of the prisms to provide autofocus and/or optical image stabilization for the camera. The shapes, materials, and arrangements of the refractive lens elements in the lens stack may be selected to capture high resolution, high quality images while providing a sufficiently long back focal length to accommodate the second prism.
