IMAGE CAPTURE ENHANCEMENT USING DYNAMIC CONTROL IMAGE
First Claim
1. A computer-implemented method comprising:
- receiving captured image frames from a camera, wherein the captured image frames comprise a first frame captured during an infrared emission, and a second frame, adjacent to the first frame, captured outside the infrared emission;
subtracting the second frame from the first frame to provide an image of a reflected infrared component; and
removing, from the reflected infrared component, a previously obtained background image of the environment space to enhance a subject in the image.

Abstract
Embodiments of the present invention provide systems and methods for image capture with infrared emitters, with associated computer control and processing for providing consistent and high quality image data. Image data of consecutive frames from a camera is obtained, with a first frame being taken during an emission of infrared light directed at a scene to be captured by the camera and a second frame being taken without an emission of infrared light. The consecutive frames provide a dynamic control image of the captured scene. The image data may be used to support photometric sampling techniques used in building geometric models for subject recognition in camera imagery in variable lighting environments.

15. A computer system comprising:
-
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 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 capture 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. - View Dependent Claims (16, 17, 18, 19, 20)
