Abstract: A sensor actuator includes an image sensor configured to convert incident light into an electrical signal, and first and second driving parts, configured to move the image sensor in first and second directions, respectively, each of the first and second driving parts includes one or more drivers each includes a wire having a change in length configured to move the image sensor. The one or more drivers in the second driving part is configured to move the image sensor and the first driving part together, and the first and second directions are different from each other.

Abstract: A camera module includes: a fixing member; a base member slidably coupled to the fixing member; a driving unit coupled to the base member and including a main gear; a gear structure rotatably coupled to the base member to engage with the main gear; a first camera connected to the gear structure to be rotated; and a second camera connected to the gear structure to be rotated in a direction opposite to the first camera. A first position of the base member when the main gear is rotated in a first rotation direction is different from a second position of the base member when the main gear is rotated in a second rotation direction that is opposite to the first rotation direction.

Abstract: A camera module includes a housing having an internal space, a lens module disposed in the internal space to be slidably movable with respect to the housing, and a driving portion configured to provide a driving force to move the lens module in an optical axis direction. The driving portion includes a wire portion having a length that changes as power is applied to the wire portion, the lens module comprises a guide portion configured to guide a movement of the lens module in the optical axis direction, and the wire portion is in contact with and supported by the guide portion.

Abstract: A lens actuator includes: a lens barrel accommodating one or more lenses; and a driving unit to move the lens barrel along an optical axis direction. The driving unit includes a driving wire, at least a portion of which is extended in the optical axis direction, and a length of which is changed as voltage is applied thereto, and a driving transmission unit connected to the driving wire to move the lens barrel along the optical axis direction as the length of the driving wire is changed such that a distance by which the lens barrel is moved by the driving transmission unit is greater than an amount of change in the length of the driving wire.
