Abstract:
A method of adjusting an optical setting of an optical input device includes: determining a desired level of an intensity of captured reflected light reflected from a tracking surface; determining whether a surface changing event occurs; and adjusting an optical setting of the optical input device according to the desired level of the intensity of the captured reflected light if it is determined the surface changing event occurs.
