Abstract: When a lens assembly of an imaging device is subject to impacts, vibrations or other movements, and an optical axis of a lens assembly is varied as a result of the movements, blurring or pixel shifts may be reduced or eliminated at a targeted location within an image plane by shifting a lens of the lens assembly by a distance calculated based on an angle corresponding to the selected location, an angular difference between orientations of the optical axis, and a focal length of the imaging device. If the distance would result in a pixel shift at a center of the image plane in excess of a maximum allowable pixel shift, an alternate distance may be calculated based on the maximum allowable pixel shift, the angular difference between orientations of the optical axis, and the focal length of the imaging device.
