(under subclass 554) Subject matter wherein image stabilization is accomplished via the movements of a light bending (i.e., refracting) optical element.
(1) Note. Gyroscopically supported lenses to compensate for motion belong in this subclass.
(2) Note. Compensation for the bending of periscopes also belongs here if the optical elements are movable for the compensation.
(3) Note. The refractive elements are moved individually or as a unit to compensate for the instability of the image.
(4) Note. Motion picture cameras (Class 352) would take precedence over this class but cross references for motion picture camera lenses that are gyroscopically controlled for image stabilization should go in this subclass.
