Abstract: A method, system, and article of efficient illuminator and camera sensor synchronization to capture images comprises generating a sequence of frames each associated with a captured image and comprising operating an electronic shutter using vertical-blanks (vblanks) occurring between the last reset of a previous frame and a first read of a current frame consecutively after the previous frame of the sequence of frames. The generating also comprises receiving, by at least one camera sensor, from at least one infra-red-related illuminator and limited to a time within or equal to the vblanks so that the illuminator is turned on and off at the same vblank, and sensing the received light at the camera sensor to convert the light into image data to form the frames in the sequence of frames.
