Abstract

The technique consists in the use of an anamorphic lens, a cone realized with a mirror face or an equivalent optic prism, that must be placed in front of the lens of a video/digital/photocamera or of a projector so that it is possible to generate a conic anamorphic image able to perform a 360 degree panoramic view.

Description

Description
Anamorphic technique for filming and projecting images of 360 degree Technical fields
The invention relates to the field of filming and projecting techniques for panoramic 360 degree images. Background art
The existing techniques of filming and projection of panoramic im- ages in 360 degree are realized with a set of several different images or with many different lens. All these techniques are really very complex and expensive.
Disclosure of technique
The technique consist in the use of an anamorphic very simple lens, a cone realized with a mirror face or an equivalent optic prism, that must be placed in front of the lens of a camera or of a projector so that the rays of light of a 360 degree scenario converge inside the frame (or vice versa) generating a conic anamorphic image able to memorize a 360 degree panoramic view. The angle of the mirror cone must be 45 degree for a correct projection, but it is possible to use different degrees to hit different possibilities. If it is used a angle less or more then 45 degree, the field of panoramic image grows and the field of projection is located in the lower or in the upper part of the space. To realize a panoramic image it is necessary to put the camera or the projector in vertical way, and the anamorphic-mirror-cone must be placed with the tip turned to the projector/camera, as shown in the attached figures. Brief description of drawings Fig. 1 , axonometric view of the system showing the relationship between camera/projector, the cone-mirror and the screen/outside view at 360 degree.
Fig. 2, section view of the system showing the way of the visual rays. Best mode for carrying out the invention
The best way to realize 360 degree projection is in realizing a mirror prism cone that may be also a little cone placed near the lens of the camera/projector. In this way the cost is really low and it is possible to realize panoramic movies and panoramic projections. For projections in a large spaces, it is interesting to use a large mirror cone placed in the center and in the top of a cylindric space where people can enter and stay inside a virtual 360 degree panoramic kinetic image.
Industrial applicability The anamorphic tool realized with a mirror-cone-prism may be produced for video/digital cameras and used as a normal wide angle lens. This technique may be used by fashion industry in showing their products, in movies realization, in virtual sets for cinema and television, in the setting up of exhibitions, museums, theatre and concert of classic and rock bands.

Claims

Claims
1. The anamorphic lens realized as cone with mirrored face, associated with lens of cameras and projectors, characterized by the use of mirror face and by the tip of the cone turned to the projector/camera.
2. The cone, with the face realized as mirror, where the improve- ment is the use as anamorphic lens in association with the lens of cameras and projectors.
3. The equivalent prism of the cone with the mirrored face, where the improvement is the use as anamorphic lens in association with the lens of cameras and projectors.
4. The ceiling of a show room or exhibition room performed as mirrored cone characterized by the use for panoramic projection of 360 degree images.
