Abstract
An optical navigation system, e.g. optical mouse, determines optical navigation quality by examining some or all of the photosensors of a frame or monitoring intermediate or final results of the motion estimation system. The optical navigation quality is then used to determine the navigation output produced by the optical navigation system.
