A motion picture projector, camera, and film for a panoramic motion picture. The projector advances a film strip along a cylindrical path for the projection of a panoramic image. Substantially identical condenser lenses with light sources are mounted inside the cylindrical film path aligned with and connected to projection lenses outside the cylindrical path. The condensers and projection lenses are rotated together at a speed other than the speed of movement of the film. The ratio of the angular velocity of the film to the angular velocity of the projection lenses is n:(n-1), where n is the number of projection lenses. Each projection lens projects a section of the film that has a length of 360.degree./(n(n-1)). The film strip has n series of portions representing n sectors of the panoramic scene, the time sequential portions of one series having n-1 intervening portions of other series therebetween. A camera for producing the film is similar in layout to the projector. The camera moves film and objective lenses with shutters and diaphragms at an angular velocity ratio of n:(n-1).
Projector for the projection of a panoramic image through an angle of substantially 360.degree., said projector comprising means for supporting a transparent film with a picture to be projected in such a way that part of the film takes on the shape of a cylindrical surface, a number of substantially identical condensers with a light source, said condensers being mounted inside the cylindrical surface and symmetrically with respect to the axis of said surface, said condensers being aligned and connected with the same number of substantially identical projection lenses, said lenses being mounted outside the cylindrical surface and also symmetrically with respect to the axis of the cylindrical surface, and means for rotating the condensers together with the projection lenses about the axis of the cylindrical surface, characterized in that means are provided for the supply and removal of the film and for advancing the film along said cylindrical surface, and that the means for rotating the condensers with the projection lenses and the means for transporting the film are connected in such a way that the ratio of the angular velocity of the film to the angular velocity of the projection lenses is n:(n- 1), wherein n is the number of projection lenses.
A motion picture camera for the manufacture of a film to be used in a panoramic projector, characterized in that said camera comprises means for the supply, removal and guidance along a cylindrical surface of a film strip for exposure, objectives with shutters and diaphragms disposed outside said cylindrical surface and symmetrically with respect to the axis of this surface, as well as means for rotating the objectives and the film about the axis of the cylindrical surface in such a way that the ratio of the angular velocity of the film to the angular velocity of the objectives is n:(n-1), wherein n is the number of objectives.
