Abstract
Abstract The subject of this invention is equipment and a process for taking and reproducing stereoscopic images in black and white or colour, static or moving, without disturbing the observers by placing an optical or mechanical device in front of them and not requiring coherent light either spatial or temporal (laser) for taking or reproducing them.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
- Equipment for obtaining three-dimensional moving images, that is four-dimensional images in both colour and in black and white, characterised by the use of a means of taking stereoscopic images with several optical objective lenses belonging to a single camera or to several different ones, the optical centres of which are on a horizontal plane; and by a means of reproduction which consists of the same number of projection objective lenses, belonging to a single projector or to different ones, as objective lenses used for the takes, arranged in such as way that they project their images onto a screen made of transparent optical material composed of an optical screen of vertical cylinders which reproduce the horizontal parallax, and of another optical screen of horizontal cylinders which allow observation through background projection of the vertical component of the image.
Claim 2
Dependent Claim
139 words
- Equipment for obtaining three-dimensional moving images, that is four-dimensional images in both colour and in black and white, characterised by the use of a means of taking stereoscopic images with several optical objective lenses belonging to a single camera or to several different ones, the optical centres of which are on a horizontal plane; and by a means of reproduction which consists of the same number of projection objective lenses, belonging to a single projector or to different ones, as objective lenses used for the takes, arranged in such as way that they project their images onto a screen made of transparent optical material composed of an optical screen of vertical cylinders which reproduce the horizontal parallax, and of another optical screen of horizontal cylinders which allow observation through background projection of the vertical component of the image.
Claim 3
Dependent Claim
24 words
- Equipment as in Claim 1, wherein the optical screen of vertical cylinders above is substituted with spherical lenses of the same optical power.
Claim 4
Dependent Claim
38 words
- Equipment as in the previous Claims, wherein the transparent optical screen is substituted with another specular screen of the same absolute value of vertical and horizontal optical power, the observation being made in this case by reflection.
Claim 5
Dependent Claim
47 words
- A process for obtaining three-dimensional moving images, that is four-dimensional, both in colour and in black and white, wherein the images are taken with several optical objective lenses and are reproduced, by projection, on an optical screen, where they merge into a single observable stereoscopic image.
Claim 6
Dependent Claim
47 words
- A process for obtaining three-dimensional moving images, that is four-dimensional, both in colour and in black and white, wherein the images are taken with several optical objective lenses and are reproduced, by projection, on an optical screen, where they merge into a single observable stereoscopic image.
