Abstract
A lens driving apparatus includes a lens holder configured to accommodate a lens; a carrier configured to accommodate the lens holder; a first optical image stabilization (OIS) driver, disposed outside of the lens holder, configured to drive the lens holder in a first direction perpendicular to an optical axis; and a second OIS driver, disposed outside of the carrier to oppose the first OIS driver and having the lens holder interposed therebetween, configured to drive the carrier in a second direction perpendicular to the optical axis and the first direction.
Claims23
A lens driving apparatus comprising:
- a lens holder configured to accommodate a lens;
- a carrier configured to accommodate the lens holder;
- a lens driver configured to drive the lens holder in an optical axis direction or in a first direction perpendicular to an optical axis, or drive the carrier in a second direction perpendicular to the optical axis direction and the first direction;
- and
- an elastic member configured to connect the lens holder to the carrier, and provide the lens holder with a restoring force in the optical axis direction or the first direction.
A lens driving apparatus comprising:
- a lens holder configured to accommodate a lens;
- a carrier configured to accommodate the lens holder;
- a first driving unit configured to drive the lens holder in an optical axis direction and a first direction perpendicular to an optical axis;
- and
- a second driving unit configured to drive the carrier in a second direction perpendicular to the optical axis and the first direction.
An apparatus comprising:
- a lens holder configured to move in an optical axis direction or in a first direction perpendicular to an optical axis;
- a carrier configured to accommodate the lens holder and move in a second direction perpendicular to the optical axis direction and the first direction;
- an elastic member configured to connect the lens holder to the carrier, and provide the lens holder with a restoring force in the optical axis direction or the first direction;
- and
- a rolling member interposed between the carrier and a base configured to seat the carrier.
2020 The apparatus of claim 19, wherein
- the AF driver includes an AF driving magnet disposed on a first outer surface of the lens holder to face an AF driving coil with a gap therebetween,
- the first OIS driver includes a first OIS driving magnet disposed on the first outer surface of the lens holder to face a first OIS driving coil with a gap therebetween, and
- the second OIS driver includes a second OIS driving magnet disposed on a second outer surface of the carrier to face a second OIS driving coil with a gap therebetween.
The apparatus of claim 20, wherein
- the first OIS driving magnet comprises a pair of magnets, disposed on opposing sides of the first outer surface of the lens holder and having the AF driving magnet interposed therebetween.
The apparatus of claim 20, wherein
- the first OIS driving magnet includes regions divided in the first direction with different magnetic poles.
