Abstract
A photo-screen device for a real image projection system includes a transparent or semi-transparent material having a fixed or static image applied to the surface thereof, wherein the photo-screen is positioned so as to intersect a real image beampath of the real image projection device. In an alternative embodiment, a method for producing a photo-screen device for a real image projection system includes the steps of printing colors thereon in reverse order and positioning the photo-screen such that the non-printed side faces a viewer of the real image.
