Abstract
A lens module includes a lens barrel, a first lens, a second lens, a plurality of electrostrictive members and a controlling unit. The first lens has a first optical axis thereof, the second lens has a second optical axis thereof, the first and second lenses being received in the lens barrel. The electrostrictive members are arranged in the lens barrel and connected with the second lens. The controlling unit is configured for controlling the electrostrictive members so as to adjust the second optical axis of the second lens to be in alignment with the first optical axis of the first lens. A camera module using the lens module is also provided.
Claims20
A lens module, comprising:
- a first lens having a first optical axis;
- a lens barrel;
- a second lens having a second optical axis, the second lens being received in the lens barrel;
- a plurality of electrostrictive members arranged in the lens barrel and connected with the second lens, wherein in a nonoperating state of the lens module, an angle between an electrostrictive direction of each of the electrostrictive members and the second optical axis of the second lens is an acute angle or an obtuse angle;
- and
- a controlling unit for controlling the electrostrictive members so as to adjust the second optical axis of the second lens to be in alignment with the first optical axis of the first lens.
A lens module, comprising:
- a first lens having a first optical axis;
- a lens barrel;
- a second lens having a second optical axis, the second lens being received in the lens barrel;
- a plurality of electrostrictive members arranged in the lens barrel and connected with the second lens;
- and
- a controlling unit for controlling the electrostrictive members so as to adjust the second optical axis of the second lens to be in alignment with the first optical axis of the first lens;
- wherein the second lens has a central active portion and a peripheral inactive portion surrounding the central active portion, the peripheral inactive portion having a plurality of anchoring posts thereon, the electrostrictive members each defining a through hole engagably receiving a respective one of the anchoring posts therein.
A lens module, comprising:
- a first lens having a first optical axis;
- a lens barrel;
- a spacer;
- a second lens having a second optical axis, the second lens being received in the lens barrel;
- a plurality of spring members attached on the spacer, the spring members cooperatively supporting the second lens;
- a plurality of electrostrictive members arranged in the lens barrel and connected with the second lens;
- and
- a controlling unit for controlling the electrostrictive members so as to adjust the second optical axis of the second lens to be in alignment with the first optical axis of the first lens;
- wherein the spacer has a plurality of first protrusions thereon, the second lens has a plurality of second protrusions thereon, the second protrusions of the second lens facing toward the first protrusions of the spacer, the spring members being sandwiched between the first protrusions of the spacer and the second protrusions of the second lens.
