초록

A method for focusing a miniature camera includes providing a current through a coil, moving a lens of a camera based on the current to adjust a focus of the camera, and limiting movement of the lens along an optical path of the camera.

대표청구항 ▼

1. A method, comprising: providing a variable current through a coil; andmoving an optical element, based on the current, with respect to an image sensor, the optical element being disposed on a stage comprising a magnet resiliently suspended adjacent to the coil for movement relative to the coil; and whereinthe coil is wound around an axis that is perpendicular to a direction of movement of the optical element; andthe direction of movement of the optical element comprises a direction of movement toward and/or away from the image sensor along an optical axis of the optical element. 2. The method of claim 1, wherein: the optical element comprises a lens disposed on a ring shaped lens mount;the lens mount is disposed on the stage; andthe stage is constrained by a snubber mechanism against movement other than rectilinear movement along an axis that is parallel to an optical axis of the lens. 3. The method of claim 1, wherein the stage comprises a micro electromechanical systems (MEMS) stage. 4. The method of claim 1, wherein the stage moves with the optical element; andthe stage remains within a plane defined by the stage itself when the stage moves. 5. The method of claim 4, wherein the magnet and the optical element are disposed on opposite sides of the stage. 6. The method of claim 1, further comprising: providing a housing around the optical element; andattaching the coil to the housing, whereby the coil is aligned relative to the magnet by the housing. 7. The method of claim 1, further comprising controlling the current through the coil using a processor to adjust the focus of an image on the image sensor. 8. A device, comprising: an imaging sensor;a coil;circuitry for providing a variable current through the coil; andan optical element disposed on a stage comprising a magnet resiliently suspended adjacent to the coil for movement relative to the coil; and whereinthe coil is wound around an axis that is perpendicular to a direction of movement of the optical element; andthe direction of movement of the optical element comprises a direction of movement toward and/or away from the imaging sensor along an optical axis of the optical element. 9. The device of claim 8, wherein the optical element comprises a lens disposed on a ring shaped lens mount, wherein the lens mount is disposed on the stage, and wherein the stage is constrained by a snubber mechanism against movement other than rectilinear movement along an axis that is parallel to an optical axis of the lens. 10. The device of claim 8, wherein the stage comprises a micro electromechanical systems (MEMS) stage. 11. The device of claim 8, wherein: the stage moves with the optical element; andthe stage remains within a plane defined by the stage itself when the stage moves. 12. The device of claim 8, wherein the magnet and the optical element are attached to the stage in a planar fashion. 13. The device of claim 12, wherein the magnet and the optical element are disposed on opposite sides of the stage. 14. The device of claim 8, further comprising: a housing around the optical element; and whereinthe housing holds the coil and aligns the coil relative to the magnet. 15. A method, comprising: coupling an optical element to a magnet via a stage; andsuspending the magnet adjacent to a coil via the stage so that the optical element and the magnet move conjointly in response to a variable current through the coil; and whereinthe coil is wound around an axis that is perpendicular to a direction of movement of the optical element; andthe direction of movement of the optical element comprises a direction of movement toward and/or away from an imaging sensor along an optical axis of the optical element. 16. The method of claim 15, wherein: the optical element comprises a lens disposed on a ring shaped lens mount;the lens mount is disposed on the stage; andthe stage is constrained by a snubber mechanism against movement other than rectilinear movement along an axis that is parallel to an optical axis of the lens. 17. The method of claim 15, wherein the stage comprises a micro electromechanical systems (MEMS) stage. 18. The method of claim 15, wherein the stage remains within a plane defined by the stage itself when the stage moves conjointly with the magnet and the optical element. 19. The method of claim 15, wherein the step of coupling the optical element to the magnet via the stage comprises assembling the stage, the magnet, and the optical element in a stacked fashion. 20. The method of claim 19, wherein the magnet and the optical element are disposed on opposite sides of the stage. 21. The method of claim 15, further comprising: providing a housing around the optical element; andattaching the coil to the housing, whereby the coil is aligned relative to the magnet by the housing.
