Abstract
An image projection system capable of projecting images to multiple screens or viewing surfaces. The system uses a moveable mirror to direct the projected images to the screens. The moveable mirror may work in concert with one or more fixed mirrors to reflect the projected images to screens in a variety of configurations relative to the projector.
Claims20
A multiple-image projector system comprising:
- an image projector for projecting an image retrieved from an image storage means containing images to be displayed on a plurality of screens;
- a plurality of fixed mirrors;
- a moveable mirror placed in the path of the projected image and positionable to reflect the projected image to a selected fixed mirror;
- wherein each fixed mirror is positioned to reflect the projected image to one of the plurality of screens;
- and
- wherein the moveable mirror moves continuously and wherein the moveable mirror has no more than one highly reflective surface.
