Abstract
A method of inhibiting a subject's eyes from being exposed to projected light when the subject is positioned in front of a background on which an image is displayed comprises capturing an image of the background including the displayed image, processing the captured image to detect the existence of the subject and to locate generally the subject and masking image data used by the projector to project the image corresponding to a region that encompasses at least the subject's eyes, the image data masking compensating for differing camera and projector viewpoints.
