摘要： An optical navigation system with a lift detection module is provided for preventing cursor movement if the optical navigation system has been lifted from the navigation surface. The optical navigation system may include an image sensor, a controller and a lift detection module. The lift detection module may be operatively coupled with the image sensor and the controller to selectively report a motion data upon determining a lift by comparing the average of the photosensitive pixel elements with a pixel element threshold value and the surface quality value with a surface quality threshold value. The lift detection module may be incorporated in a microcontroller, wherein the microcontroller may be added to a navigation system to provide an additional lift detection feature.
