OPTICAL IMAGE STABILIZATION MECHANISM

Abstract

The invention relates to an optical image stabilization (OIS) mechanism, comprising a movable frame comprising a first groove and a stationary frame comprising a second groove, an OIS moving element, and first, second, and third ball bearings forming the OIS plane, wherein the first ball bearing is set in the rail formed by the first and second grooves, wherein the ball bearing is positioned between the movable frame and the stationary frame and allows first and second movements of the movable frame relative to the stationary frame, wherein the first movement is a rotational movement performed around an axis of rotation which coincides with the position of the first ball bearing and is perpendicular to the OIS plane, and wherein the second movement is a linear movement along the rail. Furthermore, the invention reveals a method for providing the OIS mechanism.
