Optical image stabilizer for camera lens assembly
First Claim
1. An optical image stabilizer for a camera lens assembly, comprising:
- an image sensor;
a lens assembly mounted on an optical axis of the image sensor;
a housing in which the lens assembly is disposed;
a first axis rotator surrounding and engaged with the lens assembly, wherein the first axis rotator is configured to rotate the lens assembly around a first axis that is perpendicular to the optical axis;
a second axis rotator disposed between the first axis rotator and the housing, wherein the second axis rotator is configured to rotate the lens assembly around a second axis that is perpendicular to a plane including the first axis;
a first driving portion extending from an outer surface of the second axis rotator, through the second axis rotator, to an outer surface of the first axis rotator, wherein the first driving portion is configured to rotate the first axis rotator around the first axis; and
a second driving portion extending from an outer surface of the housing, through the housing, to the outer surface of the second axis rotator, wherein the second driving portion is configured to rotate the second axis rotator around the second axis.

Abstract
An optical image stabilizer for correcting an image blurred by shaking of a hand while an object is photographed using a mobile communication terminal is provided. The optical image stabilizer includes an image sensor. A lens assembly is mounted on an optical axis of the image sensor. A housing contains the lens assembly. A rotator provided between the housing and the lens assembly surrounding the lens assembly rotates the lens assembly around a first axis perpendicular to the optical axis and a second axis perpendicular to the first axis in engagement with the lens assembly. A driving member rotates the rotator around the first and second axes. The optical image stabilizer can be mounted in a miniaturized lightweight photographing device, so that a clear image can be captured even during vibration of a photographing device caused by hand-shaking.
