Abstract:     A theatrical imaging system for forming images where there are no image forming surfaces includes a theater having a raked audience viewing are in spaced apart relationship in front a stage. A false ceiling separates a motion picture projector and rear view projection screen, from the audience viewing area. The screen disposed above and in front of the audience provides a real image forming surface. A semi transmissive reflecting member disposed at an angle of 131/2 to 31 degrees to a vertical plane disposed normal to the average sight line of the audience member is disposed in facing relationship to the screen to generate a virtual image on the stage in the line of sight of the audience.

First Claim:
Show all 17 claims
What is claimed is:     1. Apparatus for displaying a multi-media image to an audience comprising:
  • an image projection source for projecting an image to an image forming surface;
  • real image forming surface means for providing an image to be reflected to create a virtual image to be viewed by and in front of an audience region, the real image forming surface means disposed in spaced apart relationship in front of the image projection source;
  • means for masking the real image forming surface means from the audience;
  • a stage region;
  • an audience envelope defining a region in which a significant number of individuals may be gathered as an audience for simultaneous viewing the stage region, the stage region defining regions for viewing by a far observer, a close observer and an average observer, the close observer, far observer and average observer viewing regions defining central level sightlines and limit sightlines for the stage region; and
  • a first partially transmissive reflecting member for creating a virtual image in front of the real image forming surface, the reflecting member means disposed in front and in spaced apart relationship to the real image forming surface, substantially directly in front of and substantially within the limit sight lines of the close observer, far observer and average observer viewing regions, the reflecting member disposed at an acute angle to a vertical plane in front of the line of sight of the viewing audience;
  • whereby the central sightline to the virtual image of the average observer is substantially direct, the distance of the audience is relatively close to the virtual image, and the apparatus is housed in a theater of economially modest architectural and technical construction to minimize the reflecting member size and theatre size demands.
