Abstract
An image stabilization mechanism for a camera is provided. The mechanism comprises a movement sensor capable of sensing motion of the camera, an element in an optical path of the camera, a ball and a plate acting as a bearing allowing for the element to move in a plane orthogonal to the optical path, an actuator mechanism capable of moving the element in the plane, and a processor configured to control the actuator to move the element as a response to motion of the camera as detected by the movement sensor, thereby stabilizing images from the camera. Furthermore, the processor further is configured to move the element along a secondary motion path so as to distribute wear on the plate created by the ball, and the processor is further capable of compensating for an image shift created by the secondary motion path by other means for shifting the image.
