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 9):
A mode switching method of a dual mode optical navigation device, the dual mode optical navigation device being operated on a working surface and having a first bottom surface arranged at an angle with respect to a second bottom surface, the mode switching method comprising:\n capturing an image frame of a working surface by an image sensor; calculating, using a process unit, a ratio of a bright area and a dark area in one image frame; in response to the calculated ratio of the bright area and the dark area being larger than a ratio threshold,\n switching to a first mode; and \n in response to the calculated ratio of the bright area and the dark area being within a ratio threshold range,\n switching to a second mode, wherein \n the ratio threshold range is smaller than the ratio threshold.
