  • Publication number: 20120162761
    Abstract: A method for creating an autostereoscopic display device including the steps of: providing a display array with a defined pixel arrangement for a number of views (nv), and providing a parallax barrier that is arranged before and/or behind the display array, wherein the parallax barrier structure is designed with a plurality of structural elements distributed over a barrier surface, whereby a barrier texture is formed by the totality of structural elements which runs skew over the barrier surface, each individual structural element being positioned on the barrier surface based on a virtual raster which is distributed over the barrier surface, the virtual raster is comprised of individual anchoring boxes, wherein a centre of each anchoring box defines the position of one of the totality of the structural elements on the barrier surface, and the anchoring boxes being scaled with a correction factor that is based on the display device and the number of views (nv), wherein the display array and the parallax bar

  • Publication number: 20090128900
    Abstract: An auto-stereoscopic display device consists of a display array with a defined pixel arrangement and a parallax-barrier arranged in front of and/or behind the display array. The parallax-barrier is comprised of structural elements distributed over a barrier surface, where a barrier texture is formed by the structural elements from a row of barrier lines extending obliquely over the barrier surface and of flat barrier lines.

  • Publication number: 20080136900
    Abstract: The invention relates to a method for the autostereoscopic representation of a stereoscopic original image displayed on a display unit. Said method is characterized in that individual perspective views of the stereoscopic original image are selectively allocated to perspective-dependent display structures and an autostereoscopic representation of the image is generated based on an intrinsic perspective-dependent luminance (L) of a series of activated display elements, particularly individual pixels (P), subpixels (SP), pixel groups (PG), and/or similar other perspective-dependent display structures, said luminance (L) being generated by a display unit and being measured by an image analyzing unit.

  • Publication number: 20070159476
    Abstract: The invention relates to a method for production of three-dimensional image patterns from two-dimensional image data, in particular from image data from image sequences, video films and the like. In this case, a virtual three-dimensional image framework (307) which is based on a supposition-based three-dimensional image depth graduation is generated on the basis of image information of imaged objects (303, 304, 305, 306) determined from monocular original image data, in which case the original image data is matched to the virtual three-dimensional image framework (307) in order to generate a virtual three-dimensional image model, and a range of individual images, which image the virtual three-dimensional image model, are obtained from the virtual three-dimensional image model. The virtual individual images are combined in a combination step to form a three-dimensional image pattern in order to carry out an imaging method with an additional depth effect.

  • Patent number: 7046271
    Abstract: A method for three-dimensional display in which a plurality of individual image elements ?ij are made visible simultaneously in a raster of columns i and lines j, wherein the image elements ?ij reproduce partial information from a plurality of views Ak (k1 . . . n) of a scene/object, and adjacent image elements ?ij radiate light of different wavelengths or wavelength regions is provided. In a method of the type described above, wavelength-dependent propagation directions are predetermined for the light radiated from the image elements ?ij. The propagation directions within an observation space in which an observer is situated intersect in a plurality of intersection points which correspond to observation positions. From each observation position, one eye of an observer perceives predominantly partial information of a first selection and the other eye perceives predominantly partial information of a second selection from views Ak (k=1 . . . n).

  • Patent number: 6176582
    Abstract: A system is disclosed for the three-dimensional representation of scenes and/or objects from planar layer images which are obtained from scaled representation planes in the spatial depth of the scenes and/or objects. To this end, a plurality of adjacent representation elements are provided, wherein said elements are perpendicular to the vision direction of an observer or a camera. The representation elements are arranged relative to each other so as to define a flat raster comprising a plurality of lines and columns. Two at least of these adjacent representation elements, in a line and a column of this raster, have different focal distances. The number of different focal distances corresponds to the number of scaled representation planes in the spatial depth. The representation elements having the same focal distance are always associated with the same representation planes. A portion of a planar layer image is placed in the optical axis of each representation element.
