Abstract
A system for synchronizing image capture and a light source has a first strobing light emitting diode (LED) array with a plurality of LEDs located to light an illumination area. The LED array has an on cycle during which the LED array is activated and an off cycle during which the LED array is inactivated. The system also has a camera located with a view of the illumination area. The camera has an image exposure that coincides with the on cycle of the strobing LED array.
