Abstract
A method of an optical navigation device having a plurality of different tracking modes includes: using an image sensor to sense and generate a plurality of image frames; and, controlling and changing a tracking mode of the optical navigation device from a first tracking mode into a second tracking mode in response to an event that the optical navigation device changes from a first surface operation condition into a second surface operation condition.
