1. A system for image capture enhancement, comprising:

  • one or more computer processors;

    one or more computer readable storage media;

    program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors;

    one or more infrared emitters capable of being positioned to emit infrared light on an environment space monitored by a camera capable of capturing images of the environment space;

    a control system using a processor and a memory configured to provide instructions to the processor to execute control of a sequence of emissions by the one or more emitters, wherein a sequence of infrared emissions is synchronized with a frame counter of a camera; and

    a processing system using a processor and a memory configured to provide instructions to the processor to execute processing of captured image frames of the camera, the processing system including;

    a frame receiving component configured to receive the captured image frames comprising a first frame captured during an emission, and a second frame, adjacent to the first frame, captured outside an emission;

    an adjacent frame processing component configured to subtract the second frame from the first frame to provide an image of a reflected infrared component;

    a background deduction component configured to remove, from the reflected infrared component, a previously obtained background image of the environment space to enhance a subject in the image; and

    a resultant image output component configured to output a resultant image.
