Patent number: 6963431Abstract: A method of rendering image data for full parallax autostereoscopic displays. The method is based on a double frustrum camera technique, where two cameras provide image data from opposing sides of an image plane. The near clipping plane is located on the image plane. The distance between the near clipping plane and the eyepoint of the camera frustra is adjusted to minimize or avoid clipping.Type: GrantFiled: January 28, 2002Date of Patent: November 8, 2005Assignee: Zebra Imaging, Inc.Inventors: Mark E.

Patent number: 6900904Abstract: A distributed system for producing holographic stereograms (holograms). A data acquisition station is typically remote from image processing, printing, and replicating stations. The data acquisition station is designed to maximize customer convenience, and may be the customer's own personal computer. The data acquisition station is further designed to accept a wide variety of source data and to perform whatever processing is required to deliver image data to the image processing station in an acceptable format. The data acquisition station further has processing capability to display preview images, which may be assembled by programming executing at the data acquisition station or downloaded from a server.Type: GrantFiled: February 4, 2000Date of Patent: May 31, 2005Assignee: Zebra Imaging, Inc.Inventors: Mark E.

Efficient block transform including pre-processing and post processing for autostereoscopic displays
Patent number: 6868177Abstract: Image data processing techniques utilizing multiple processes operating on one or more processors of one or more computer systems can be used to efficiently rearrange or reparameterizing image data to form hologram element (hogel) images which can then be used to produce holographic stereograms. These techniques utilize matrix manipulation of portions of image data both within a single process, and across multiple processes typically executing on different processors, and each utilizing a subset of the overall set of image data.Type: GrantFiled: October 19, 2001Date of Patent: March 15, 2005Assignee: Zebra Imaging, Inc.Inventors: Emilio Camahort, Mark E.

Patent number: 6859293Abstract: Certain types of holographic recording materials can be used to updateably record holographic stereograms formed when fringe patterns are generated through interference of an object laser beam containing image information with a reference laser beam. In this manner, calculation of fringe patterns is avoided, and instead perspective information is computed for a scene or object to be displayed, the information is downloaded to display hardware such as a spatial light modulator, and fringe patterns are subsequently generated through interference of an object laser beam containing this information with a reference laser beam in the classic hologram recording scheme. Previously recorded holographic stereograms or component hogels are updated by erasing the stereograms or component hogels and recording updated stereograms or component hogels, or by recording updated stereograms or component hogels in a separate portion of the holographic recording material.Type: GrantFiled: October 22, 2003Date of Patent: February 22, 2005Assignee: Zebra Imaging, Inc.Inventors: Michael A.

Patent number: 6795241Abstract: A system and method are provided to form a large scale full-parallax three-dimensional electronic display. Multiple lenslet pixel modules are preferably formed by combining a high resolution two-dimensional image sources with respective lenslets. For some applications each pixel module has a respective two-dimensional high resolution image source. For other applications two or more lenslet pixel modules may use respective portions of the same high resolution two-dimensional image source. One or more computer processing units may be used to provide video images or graphical image data to the high resolution two-dimensional image sources. For some electronic displays, the lenslet pixel modules form an array of projectors and an array of sensors may be disposed within the array of projectors. The array of sensors may cooperate with the array of projectors to allow interaction between one or more observers and a three-dimensional image produced by the projector array.Type: GrantFiled: December 8, 1999Date of Patent: September 21, 2004Assignee: Zebra Imaging, Inc.Inventor: Mark E.

Patent number: 6665100Abstract: Large format, highly selective display screens can be formed from a plurality of holographic optical elements. In accordance with the teachings of the present invention, systems and methods are described to provide a holographic screen for display of static and/or dynamic projected conventional two-dimensional images, two-dimensional stereograms, and holographic stereograms. One aspect of the present invention includes presenting live-image three-dimensional displays using an array of two-dimensional data projectors. Another aspect includes projecting and enlarging static or dynamic source three-dimensional images (real objects, holograms, or other autostereoscopic images).Type: GrantFiled: August 10, 2000Date of Patent: December 16, 2003Assignee: Zebra Imaging, Inc.Inventors: Michael A.

Patent number: 6631016Abstract: The current invention comprises the recording of full parallax, one-step, full color holographic stereograms so as to properly display the resultant imagery when the hologram is mounted on a curved substrate after recording. It also comprises mounting the hologram on a substrate that can be curved in one or two dimensions, thereby producing any arbitrary shape. The hologram is scalable, making it possible to create curved holograms of unlimited size. The hologram can be generated for application to one of a variety of curved substrates, including hemi-cylindrical substrates with opaque backing to allow up to 180 degrees of horizontal view zone, and full cylinders with transparent backing to allow viewing through 360 degrees horizontally. It also includes adaptation to conical, spherical, and other curved geometric and irregular topographies.Type: GrantFiled: July 18, 2001Date of Patent: October 7, 2003Assignee: Zebra Imaging, Inc.Inventors: Michael A. Klug, Mark E. Holzbach

Patent number: 6614565Abstract: A system and method are disclosed for producing and displaying a one-step, edge-lit hologram. For production, an object beam and an edge-lit reference beam are directed at holographic recording material and to interfere with one another. The holographic recording material and the object beam and edge-lit reference beam are then translated with respect to one another. The translation successively exposes multiple portions of the holographic recording material to the interference of the object beam and the edge-lit reference beam to record an edge-lit hologram on the holographic recording material. In one embodiment, the holographic recording material is moved while the object beam and the edge-lit reference beam remain generally stationary. In another embodiment, the object beam and the edge-lit reference beam move in unison with each other while the holographic recording material remains generally stationary.Type: GrantFiled: February 16, 2000Date of Patent: September 2, 2003Assignee: Zebra Imaging, Inc.Inventors: Michael Anthony Klug, Mark E.
