Abstract
A method for calibrating a value of sampling precision of an optical sensor for tracking includes: reading a precision variance and a setting precision value from a memory device; measuring the sampling precision of the optical sensor under a normal mode to generate an actually measured precision value; calculating a normalized value that is proportional to the actually measured precision value according to the precision variance, the actually measured precision value, and the setting precision value; and, calibrating the actually measured precision value by using the normalized value.
