Patent ID: 7419265

Claim:
An autosteroscopic projection arrangement comprising: a first projector, and a first filter array having a multitude of filter elements, in which the projector projects bits of partial information from views of a scene or object onto a projection screen, where the bits of partial information are rendered on image rendering elements and, having passed the filter array, are made visible to an observer, and in which the image rendering elements correspond with correlated filter elements, as regards the propagation direction of the bits of partial information, in such a way that the observer will see predominantly bits of partial information from a first selection of views with a first eye and predominantly bits of partial information from a second selection of views with a second eye, so that the observer perceives a spatial impression, a second projector, a second filter array, in which the first filter array is arranged between the projection screen and the projectors, and the second filter array is arranged in front of the projection screen and in which the first and second filter arrays have wavelength filter elements arranged in columns and rows that are transparent to light of different wavelengths or different wavelength ranges and in which the projectors project bits of partial information from views of a scene or object through at least one of the first and second filter arrays and onto the projection screen, so that bits of partial information of the views are made optically visible on the projection screen in combination or mix determined by a geometry of the arrangement, and the projection screen is divided into a grid of image rendering elements which are arranged in columns and rows and, depending on the embodiment of the filter arrays and the projectors, radiate light of particular wavelengths or wavelength ranges, with each image rendering element rendering bits of partial information of at least one of the views, and in which the second filter array arranged in front of the projection screen defines propagation directions for the light radiated by the projection screen toward the observer, in which any individual image rendering element corresponds with several allocated wavelength filters of the filter array, or one wavelength filter of the filter array corresponds with several allocated image rendering elements, in such a way that a straight line connecting a first centroid of the cross-section area of a visible portion of the image rendering element and a second centroid of the cross-section area of a visible portion of the wavelength filter represents one propagation direction, so that, from every viewing position, the observer will see predominantly bits of partial information of a first selection of views with the first eye, and predominantly bits of partial information of a second selection of views with the second eye, so that the observer perceives a spatial impression from a multitude of viewing positions.
