What is disclosed is a method and apparatus for eliminating the oscillating effect of a light source. The method having the first step of detecting a set of light intensity levels. Then, the method continues by generating a set of pulses based on the set of light intensity levels. The method then determines an oscillating frequency of the light source based upon the set of pulses. The apparatus has a light sensitive diode for detecting a light intensity level from a light source; a level detector coupled to the light sensitive diode for comparing the detected light intensity level with a predetermined level and a pulse generator coupled to the level detector for generating a set of pulses based on an output from the level detector; and, a signal processing unit coupled to the pulse generator to determine an oscillating frequency of the light source.
