A camera actuator according to an embodiment includes: a housing; a prism unit disposed in the housing; a driving part tilting the prism unit; a second pivot plate disposed on a side wall of the housing; and a first pivot plate disposed between the second pivot plate and the prism unit, wherein the prism unit includes a pulling magnet, and the prism unit is tilted with respect to a rotation reference axis of the first pivot plate or the second pivot plate while being supported by the housing by attractive force between the pulling magnet and the second pivot plate.

A camera module is provided including: a housing; a lens assembly provided in the housing to move up and down in a direction of an optical axis of an image sensor, and including at least one lens; and a driving unit that produces driving force for moving the lens assembly, arranged at a position adjacent to the lens assembly, and fixed to the housing by at least one detachable insertion member.

The lens arrangement has at least two lenses, wherein a first lens may be used for autofocus and optical image stabilization. The first lens is tilted to compensate for the shaking movement of the hand-held device and to stabilize the image to be captured on the image plane. The tilt action may occur in two degrees of freedom, wherein an actuator causes the first lens to tilt around a pivot. A second lens is a field flattener lens that compensates for the error caused by the difference between the image plane and the focus plane. The field flattener lens causes the focal plane of the first lens to lie in the image plane when the first lens is in a tilted position.

An optical unit with a shake correction function may include a movable module holding an optical element, a support body including a body part surrounding the movable module, a gimbal mechanism including a movable frame having elasticity and configured to swingably support the movable module between the movable module and the support body, a spring member connected to the movable module and the support body for holding posture of the movable module, and a shake correction drive mechanism configured to swing the movable module. When a natural vibration frequency of the movable frame is “fa”, a natural vibration frequency of the spring member is “fb”, and a vibration frequency band of a movable body on which the support body is mounted is “fw”, the natural vibration frequency “fa” and the natural vibration frequency “fb” are shifted from the vibration frequency band “fw”. Further, it may be preferable that a difference between the natural vibration frequency “fa” and the natural vibration frequency “fb” is set to be 135 Hz or more.

A camera module includes: a housing; a first frame rotatably mounted in the housing; a second frame rotatably mounted on the first frame; a reflective member mounted on the second frame; a first driver including a first magnet installed on either one of the housing and the first frame, and a first coil opposing the first magnet; and a second driver including a second magnet installed on either one of the housing and the second frame, and a second coil opposing the second magnet. The first frame is configured to rotate in a first axial direction perpendicular to an incident direction of light incident to the reflective member. The second frame is configured to rotate in a second axial direction parallel to an incident direction of light incident to the reflective member.

Provided are a lens assembly and an electronic device including the lens assembly, the lens assembly including a first reflector configured to rotate around a first rotation axis, a second reflector configured to rotate around a second rotation axis, a plurality of lenses, and an image sensor configured to generate a plurality of captured images having different capturing views based on a rotation of at least one of the first reflector or the second reflector, in which the first reflector, the second reflector, the plurality of lenses, and the image sensor are provided in sequential order from an object's side.

The present embodiment relates to a lens driving device comprising: a first housing; a second housing disposed at an inner side of the first housing; a bobbin disposed a an inner side of the second housing; a first coil disposed on the bobbin; a magnet disposed on the second housing, and facing the first coil; a second coil facing the magnet; a first support member coupled to the bobbin and the second housing; and a second support member coupled to the first housing and the second housing, wherein the second coil is disposed to be spaced apart from the first housing.

A driving mechanism is provided, including a fixed portion, a movable portion, a driving assembly and a buffering element. The movable portion is movably connected to the fixed portion for holding an optical element having a main axis. The driving assembly is disposed in the fixed portion for moving the movable portion relative to the fixed portion. The buffering element is disposed between the movable portion and the fixed portion, wherein a stopping assembly is disposed on the fixed portion and/or the movable portion to limit the range of motion of the movable portion relative to the fixed portion, the buffering element is not in contact with the movable portion or the fixed portion when the movable portion is static, and the hardness of the buffering element is less than the hardness of the stopping assembly.

In order to provide a range measurement apparatus which enables an accurate distance measurement while an anti-vibration mechanism is operated, the range measurement apparatus includes an image information acquisition unit configured to acquire an image captured by an image pickup optical system having an anti-vibration optical system, a distance information acquisition unit configured to acquire distance information regarding a distance to a subject based on the image, and a distance correction unit configured to correct the distance information based on aberration information according to a driving amount of the anti-vibration optical system.

An actuator for a reflector may include a carrier having a first groove rail at the rear, a first magnet above the carrier, a middle guide having a first guide rail to face the groove rail and having a second groove rail of a track shape at the rear, a first ball between the first groove rail and the first guide rail, a second magnet at the rear of the middle guide, a base having a second guide rail to face the second groove rail and the middle guide, a second ball between the second groove rail and the second guide rail, a circuit board with a first coil and a second coil, a pulling yoke at the front of the middle guide, and a pulling magnet at the rear of the carrier to face the pulling yoke and to generate an attractive force to the pulling yoke.
