Apparatus for displaying a multi-media image to an audience comprising: a theater having a theatrical viewing region defining an audience envelope and a stage region, the audience envelope having plural rows of audience viewing areas defining a close observer in the foremost row, a far observer in the furthest row and an average observer midway between the foremost and the far most rows; masking means for preventing the audience from observing an image projection system, the masking means disposed in facing relationship to a lateral plane, in spaced apart relationship to an audience viewing region; 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 the audience, the real image forming surface means disposed in advance of the image projection source above the masking surface means; a first partially transmissive reflecting member disposed in front of the real image forming surface to create a virtual image in front of the real image forming surface, substantially directly in front and in the viewing line of sight of the audience, the reflecting member disposed at an acute angle to a vertical plane in front of the line of sight of the viewing audience and in reflecting relationship to the real image forming surface means, the first partially transmissive reflecting member disposed at an angle of between about 131/2 to 31 degrees to a plane normal to the line of sight of the audience viewing region; and real object means for providing real objects visually perceived by an audience in combination with a virtual image reflected by by the reflecting member, the real object means disposed in advance of the reflecting member, whereby the real image is viewed by an audience in the audeince envelope as a virtual image combined with the real object means along a direct line of sight behind the reflecting member.

Claim 12

Apparatus for displaying a multi-media image to an audience comprising: a theater having a theatrical viewing region defining an audience envelope and a stage region, the audience envelope having plural rows of audience viewing areas defining a close observer in the foremost row, a far observer in the furthest row and an average observer midway between the foremost and the far most rows; masking means for preventing the audience from observing an image projection system, the masking means disposed in facing relationship to a lateral plane, in spaced apart relationship to an audience viewing region; 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 the audience, the real image forming surface means disposed in advance of the image projection source above the masking surface means; a first partially transmissive reflecting member disposed in front of the real image forming surface to create a virtual image in front of the real image forming surface, substantially directly in front and in the viewing line of sight of the audience, the reflecting member disposed at an acute angle to a vertical plane in front of the line of sight of the viewing audience and in reflecting relationship to the real image forming surface means, the first partially transmissive reflecting member disposed at an angle of between about 131/2 to 31 degrees to a plane normal to the line of sight of the audience viewing region; and real object means for providing real objects visually perceived by an audience in combination with a virtual image reflected by by the reflecting member, the real object means disposed in advance of the reflecting member, whereby the real image is viewed by an audience in the audeince envelope as a virtual image combined with the real object means along a direct line of sight behind the reflecting member.

Claim 13

Claim 14

The invention as set forth in claim 10 and in which the real image is disposed at an angle of between 5 degrees and 38 degrees; and the virtual image is greater than 0.75 meters and less than 6 meters.

Claim 15

A process for forming visual images appearing to have transparency and suspended in space comprising the steps of: projecting a first image disposed in spaced relationship to an audience envelope, along a vertical plane, upon a frosted medium to generate a first real image; orienting the opaque medium at an acute angle to the vertical plane; positioning a partially transmissive reflecting means in advance of the opaque medium to partially reflect the first image, and positioning the reflecting means in advance of the audience envelope; and orienting the partially transmissive reflecting means about an angle of between about 131/2 degrees to 31 degrees, from a vertical plane normal to a sightline of the audience envelope; whereby a virtual image is created in advance of the audience beyond the partially transmissive reflecting means, to create the illusion of an image before an audience having a depth of more than 4 rows, with commercially available glass, in a theater of reasonable architectural configuration.
