Abstract
A projector and a camera are each disposed behind a transparent projection surface. The projector is to rear-project a first image onto the transparent projection surface, whereas the camera is to capture a second image in front of the transparent projection surface. Capture by the camera of the first image as reflected back by the transparent projection surface after rearprojection by the projector, as part of the second image, is minimized.
