Abstract: An optical navigation system comprising: a control circuit; and an optical sensor, comprising a plurality of pins, wherein the optical sensor is configured to sense optical data and configured to compute motions according to the optical data. The optical sensor outputs the motions to the control circuit via a complex pin among the pins in a first mode. The optical sensor outputs data other than the motions to the control circuit via the complex pin in a second mode. The present invention also discloses an optical navigation system which shares a pin for receiving different types of data.

Abstract: A method applied into an optical navigation device, used to communicate with a remote computer device based on a transmission interface, includes: capturing image frames according to a specific frame rate to obtain actual displacement data corresponding to the captured image frames, the specific frame rate being lower than a specific reporting rate specified by the transmission interface; generating predicted displacement data based on the actual displacement data; using the actual displacement data and the predicted displacement data to form resultant displacement data which is to be outputted; and outputting the resultant displacement data to the remote computer device based on the specific reporting rate specified by the transmission interface.
