ABSTRACT:
Methods and systems for determining the frequency of the AC power supply of any pulsating light, such as fluorescent lights, for different purposes such as adjusting a camcorder's frame rate, is described in detail herein. In one embodiment a method is described that determines the frequency of the power supply, using a single sampling rate. In another embodiment two concurrent samplings of different rates are employed to determine the power supply frequency. Additionally, two exemplary systems describe the implementations of two embodiments of the presented methods.
