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.

A controller and navigation system to implement beacon-based navigation and scene-based navigation is described. The navigation system may generate position data for the controller to compensate for a misalignment of the controller relative to the coordinate system of the navigation system. The navigation system may also distinguish between a beacon light source and a non-beacon light source.

Combined beacon and scene navigation system

An optical navigation device for operation in a surface navigation mode and a free space navigation mode. The optical navigation device includes a microcontroller, a first navigation sensor, and a second navigation sensor. The first navigation sensor is coupled to the microcontroller, and the second navigation sensor is coupled to the first navigation sensor. The microcontroller processes a movement of the optical navigation device. The first navigation sensor generates a first navigation signal in a first navigation mode. The second navigation sensor generates a second navigation signal in a second navigation mode and sends the second navigation signal to the first navigation sensor. By implementing a navigation sensor to process signals from multiple navigation sensors, the cost and size of the optical navigation device can be controlled, and a small packaging design can be used.

A system and method for selectively setting an optical navigation resolution utilizes a comparison of a comparison displacement value to a threshold value to set the optical navigation resolution to an effective resolution selected from a plurality of effective resolutions. The comparison displacement value is based on at least one of a first displacement value in a first direction and a second displacement value in a second direction, which were derived for estimating motion.
