Abstract:
There is provided a mode switching method of a dual mode optical navigation device. The dual mode optical navigation device is configured to be operated on a working surface and has a first bottom surface and a second bottom surface having an included angle with the first bottom surface. The mode switching method includes: determining whether the first bottom surface or the second bottom surface contacts with the working surface; switching the dual mode optical navigation device to a first mode when identifying that the first bottom surface contacts with the working surface; and switching the dual mode optical navigation device to a second mode when identifying that the second bottom surface contacts with the working surface.

Claim (Index 19):
The dual mode optical navigation device as claimed in  claim 14 , wherein the process unit is configured to\n enter the first mode in response to the captured image frame being fully bright, and enter the second mode in response to the captured image frame containing a bright area and a dark area having a ratio within a ratio threshold range.
