Embodiments relate to a camera actuator and a camera module having the same. The camera actuator according to embodiments may have an integrated base; a first camera actuator disposed in a first area of the integrated base and a second camera actuator disposed in a second area of the integrated base. The integrated base may have a first base body; a second base body and a third base body disposed between the first base body and the second base body.

In an apparatus, two or more actuators perform optical image stabilization by tilting a lens module of a camera unit when installed in the camera unit between the lens module and an image sensor. A variable prism is sandwiched between the lens module and the image sensor when the apparatus is installed in the camera unit for maintaining focal plane of the lens module on the image sensor independently of optical image stabilization operations caused by the tilting of the lens module.

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 device comprises an image sensor, a first moving module and two groups of second moving modules. The first moving module is connected to the image sensor. The first moving module is activated to move the image sensor linearly along a first axis. The second moving module is connected to the image sensor. The second moving module is activated to move the image sensor linearly along a second axis, which intersects with the first axis. The two groups of second moving modules are activated simultaneously to rotate the image sensor around a third axis, which is orthogonal to the first and second axes, respectively. The image sensor compensates for the image by linear movement in the direction of the first axis and the second axis and can also compensate for the image by rotation in the direction of the third axis to achieve three-axis image stabilization.

An embodiment of the present invention discloses a camera actuator comprising: a housing; a mover disposed in the housing and including protrusions on one surface which protrude toward the housing; and a driving unit disposed in the housing and rotating the mover on the basis of a first direction or a second direction perpendicular to the first direction, wherein the protrusions comprise: a first protrusion disposed on the one surface; a second protrusion spaced apart from the first protrusion; and a third protrusion separated from the first protrusion by a distance greater than from the second protrusion, and wherein the housing comprises: a groove in which the first protrusion is seated on an inner surface corresponding to the one surface; a first hole through which the second protrusion passes; and a second hole through which the third protrusion passes, wherein a side surface of the second protrusion is spaced apart from the first hole, and the housing includes a protruding part disposed on a side of the second hole and extending toward the third protrusion.

An optical actuator that comprises an inside holder that can hold an optical path bending member, an outside holder supporting the inside holder such that the inside holder can pivot around a first axis, and a drive unit making the inside holder pivot. Either end part of the inside holder is rotatably supported on the outside holder. The drive unit has: an ultrasonic motor supported on the outside holder, and an intermediate part supported on the inside holder. The ultrasonic motor has an oscillator that resonates, and the intermediate part has a fan-shaped contact part that contacts the oscillator.

A camera may include an optical components holder to hold optical components (e.g., one or more lenses and a light folding element) of the camera. The optical components holder may be formed using an insert-molding processor including a metal frame. One portion of the metal frame may form an upper wall of a portion of the optical components holder that holds the light folding element. Another portion of the metal frame may be at least partially exposed from a side wall adjacent the upper wall of the portion of the optical components holder. In addition, the camera may include a protection structure to protect the optical components holder from colliding with another component of the camera or a mobile multipurpose device.
