Patent ID: 6860604

Claim:
A method for projecting an image onto a projection screen without said image being projected onto a presenter moving about in front of said screen, and without said presenter casting a shadow, said method comprised of the following steps, a) generating a left and right correction of an image simultaneously projected onto said screen from each of two positions using respective first and second projectors that are off-axis on opposite sides of the centerline of said screen and where both projections of said image register on said screen as a single image, b) generating a center of mass of said presenter's silhouette, c) locating a vertical join line on said screen directly behind said presenters center of mass, d) inhibiting that portion of the projected image from the first projector that extends to the right of said join-line, e) inhibiting that portion of the projected image from the second projector that extends to the left of said join-line thereby providing the full projected image on the screen from the left and right image segments, without either segment projecting said image onto said presenter, and without casting said presenter's shadow onto the screen.
