Error corrected optical navigation system

An optical navigation system, comprising:

• an image sensor capable of optical coupling to a surface of an object, wherein the image sensor is capable of capturing successive images of areas of the surface;
• a data storage device, wherein the data storage device is capable of storing successive images captured by the image sensor;
• and
• a navigation circuit, wherein the navigation circuit comprises a first digital circuit capable of determining an optical displacement estimate for a relative displacement between the image sensor and the object obtained by a comparison of the images, wherein the navigation circuit further comprises a second digital circuit capable of determining a mechanical displacement estimate for the relative displacement obtained from consideration of a mechanical characteristic associated with the optical navigation system, and wherein the navigation circuit comprises a third digital circuit capable of determining an adjusted displacement estimate obtained from the optical displacement estimate and the mechanical displacement estimate.
