US Patent 8711235 Image stabilization

A system to stabilize images of a digital camera adjusting to unintentional movements of the camera during capture of an image has been achieved. A gyroscopic sensor senses any movement of a camera by angular speed detection and via an electronic regulator at least two linear motors move an x-y table, carrying an optical sensor or a lens barrel of the camera, in a way to adjust the optical sensor to these movements. Position sensors, as e.g. sensors integrated in the linear motors, capacitive sensors, inductive sensors, or Hall sensors, sense the actual position of one or more movable plates of the x-y table and feed it back to the regulator. The movable plates of x-y table are guided by a multitude of rolling elements, e.g. ball bearings.
