Method and system for synchronizing illumination timing in a multi-sensor imager

Abstract

Examples embodiments of a method and system for synchronizing active illumination pulses in a multi-sensor imager is provided. Example embodiments of the method disclosed herein include the provision of an illumination pulse for each of N sensors, each of N illumination pulses are set to have the same pulse period and active pulse width. Moreover, example embodiments include setting the active width pulse for each of the N illumination pulses to have maximum exposure time for each of N image sensors, and in further examples, ensuring that the time to capture a frame plus the time interval between subsequent image captures is the same for each sensor. In yet further examples, an offset period between subsequent frame synchronous signals is determined. In yet further example embodiments, an interval between frame captures is adjusted and a negative edge of the frame synchronous signal and an illumination pulse is aligned.
