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 8):
A dual mode optical navigation device, configured to operate in a first mode or a second mode on a working surface, the dual mode optical navigation device comprising:\n a first bottom surface; a second bottom surface arranged at an angle with respect to the first bottom surface; a light source configured to illuminate the working surface through the first bottom surface; an image sensor configured to capture an image frame of the working surface through the first bottom surface; and a process unit configured to\n calculate a first average brightness of a fully bright image frame, and enter the first mode in response to the first average brightness being larger than a brightness threshold, and \n calculate a second average brightness of a bright area and a dark area contained in one captured image frame, and enter the second mode in response to the second brightness within a brightness threshold range.
