Abstract
An asynchronous camera/projector system includes a projection screen, having a key color, a projector, oriented to provide a sequenced background image to the screen, and a camera, located in front of the screen, and oriented to capture a sequenced image of the screen and a real object positioned in front of the screen. The camera and projector operate out of phase, so that the camera does not record the background image.
