A METHOD AND SYSTEM FOR SYNCHRONIZING ILLUMINATION TIMING IN A MULTI-SENSOR IMAGER

A method and system for synchronizing active illumination pulses in a multi-sensor imager is provided. The method has the steps of: providing an illumination pulse for each of N sensors from an illumination control block; setting each of N illumination pulses to have the same pulse period and active...

description	A method and system for synchronizing active illumination pulses in a multi-sensor imager is provided. The method has the steps of: providing an illumination pulse for each of N sensors from an illumination control block; setting each of N illumination pulses to have the same pulse period and active pulse width; setting the active width pulse for each of N illumination pulses to have maximum exposure time for each of N image sensors; ensuring during initialization of image capture that the time to capture a frame plus the time interval between subsequent image captures is the same for each sensor; monitoring the frame synchronous signal and corresponding illumination pulse for each sensor; obtaining the offset periods between subsequent frame synchronous signals from the monitoring step; adjusting the interval between frame captures; and aligning the negative edge of the frame synchronous signal and the corresponding illumination pulse.
