Abstract
Abstract The invention includes a camera that receives light from a field of view, produces signals representative of the received light, and intermittently reads the signals to create a photographic image. The intermittent reading results in intermissions between readings. The invention also includes a radiant energy source that works with the camera. The radiant energy source produces a beam of radiant energy and projects the beam during intermissions between readings. The beam produces a light pattern on an object within or near the camera's field of view, thereby identifying at least a part of the field of view. The radiant energy source is often a laser and the radiant energy beam is often a laser beam. A detection mechanism that detects the intermissions and produces a signal that causes the radiant energy source to project the radiant energy beam. The detection mechanism is typically an electrical circuit including a retriggerable multivibrator or other functionally similar component. The invented method is used with a camera that is aimed toward a field of view by a light beam that produces a light pattern identifying at least a part of the field of view. The method photographs the field of view without photographing the light pattern produced by the light beam. The method includes the steps of receiving light, producing signals representative of the received light, intermittently reading the signals to create a video photograph, where the intermittent reading results in intermissions between readings, recognizing the intermission and causing the light beam to produce the light pattern during intermissions only.
