Patent number: 7692605Abstract: This invention describes methods and systems for correcting frame position error on one category of volumetric 3D displays that generates volumetric 3D images by using a rotary mechanism to move a screen to sweep a volume and projecting 2D profile images on the screen. The screen motion is in general rotating or reciprocating and a mechanism of rotational nature is generally applied to drive the motion. The method has three major steps. The first step provides a measure of the frame position error with respect to the theoretical position. The error is a periodical function of the angular position of the moving screen, due to the nature of the mechanisms. The second step constructs a correction function that shifts the position of frame image of each frame with respect to the frame center to compensate the error. The error measurement and the construction of the correction function can be performed statically or dynamically.Type: GrantFiled: June 20, 2005Date of Patent: April 6, 2010Inventor: Che-Chih Tsao

Publication number: 20090115783Abstract: A 3D viewing system captures offset images from off-axis camera perspectives inclined to a normal of base plane of a scene that includes one or more objects projecting from the base plane. The offset images, which take a planar form, are displayed from a display surface at an off-axis viewing perspective that is inclined to a normal of the display surface similar to the inclination of the off-axis camera perspective to the normal of the base plane. The offset images undergo a distortion to counteract a keystone distortion associated with the off-axis viewing perspective. The base plane of the scene is oriented parallel to the display surface, and the objects projecting from the base plane appear to project from the display surface.Type: ApplicationFiled: November 2, 2007Publication date: May 7, 2009Applicant: DIMENSION TECHNOLOGIES, INC.Inventor: Jesse B.

Publication number: 20090102915Abstract: The invention relates to stereo projection systems for displaying stereopaired images on mirror-spherical or parabolic screens and for collectively watching a stereo effect without using stereo spectacles. Said invention makes it possible to continuously dynamically superimpose the projections of the left and right picture frames of a steropair with the user's left and right eyes, respectively. Such impositions are carried out simultaneously and independently for each viewer.Type: ApplicationFiled: April 25, 2006Publication date: April 23, 2009Inventor: Svyatoslav Ivanovich Arsenich

Patent number: 7522257Abstract: A system for a 3-D Phenomenoscope to view 3-dimensional special effects in motion pictures, and a method by which ordinary 2-dimensional motion pictures can be viewed as a 3-dimensionsal experience are disclosed. It provides (a) a 3-D Phenomenoscope with right and left lenses, where the degree of darkness of the right and left lenses can be individually controlled; (b) a digital photo sensors that can capture the viewed motion picture as successive images and convert the captured frames to digital images for processing; (c) a computer processor and a computer program to process the successive images and identify lateral motion synchronization events, and (d) a control unit to provide individual control for the light-reduction or darkening of the right or left lens based on the identified synchronization events. These system and method allow any motion picture to be viewed with the visual effect of 3-dimensions.Type: GrantFiled: March 10, 2006Date of Patent: April 21, 2009Inventors: Kenneth Jacobs, Ronald Steven Karpf

Patent number: 7513623Abstract: Systems and methods for generating a true 3-D display, where each of a viewer's eyes not only sees a different scene, but the scene changes continuously as the viewer moves his/her head or change his/her position from one angular location to another angular location with respect to the display screen. In one embodiment, a system comprises a set of 2-D image projectors and a display screen. The 2-D image projectors are configured to project individual 2-D images substantially in focus on the display screen. The display screen then diffuses (or reflects) each pixel from each of the 2-D images into a small angular slice. This enables the viewer observing the display screen to see a different one of the 2-D images with each eye. Further, the image seen by each eye varies as the viewer moves his or her head with respect to the display screen.Type: GrantFiled: April 17, 2007Date of Patent: April 7, 2009Assignee: Third Dimension IP LLCInventor: Clarence E.

Patent number: 7508485Abstract: This invention directs to a video/motion picture displaying apparatus for viewing via 3D spectacles with an internal 3D synchronizing unit including an image capturing means, a synchronizing means to identify synchronization events according to a set of synchronization rules, and a transmitting unit. It further directs to a 2D video/motion picture embedded with synchronizing signals produced with the same synchronization rules. The invention also discloses a 3D synchronizing signal composing/embedding device for embedding synchronizing signals to a 2D video/motion picture including a data capturing means, a converting means, a synchronizing means and a composing means or an embedding means. It also teaches a related 3D control device configured to acquire and utilize the embedded synchronizing signals to control the transmission of light of the 3D spectacles.Type: GrantFiled: October 30, 2007Date of Patent: March 24, 2009Inventors: Kenneth Martin Jacobs, Ronald Steven Karpf

Patent number: 7503656Abstract: A projection system includes an image projection apparatus window and a transparent holographic screen deflecting light from the image projection apparatus into discrete, mutually spaced directions so that an area which is free from images is formed between identical images. Projected, mutually spaced holographic frames of the image is visualized by the holographic screen that includes a film layer which is partially illuminated multiple times at different pick-up angles to the same object of an image, so that the film layer has hologram images of the same object at mutually different pick-up angles. The transparent screen may include many holographic film layers, in which each film layer is illuminated once at different pick-up angles to the same object, so that each film layer has one hologram image of the object at a different pick-up angle.Type: GrantFiled: April 29, 2004Date of Patent: March 17, 2009Assignee: Koninklijke Philips Electronics, N.V.Inventor: Holger Mönch

Patent number: 7490941Abstract: The present invention relates to a three-dimensional (3D) hologram display system. The 3D hologram display system includes a projector device for projecting an image upon a display medium to form a 3D hologram. The 3D hologram is formed such that a viewer can view the holographic image from multiple angles up to 360 degrees. Multiple display media are described, namely a spinning diffusive screen, a circular diffuser screen, and an aerogel. The spinning diffusive screen utilizes spatial light modulators to control the image such that the 3D image is displayed on the rotating screen in a time-multiplexing manner. The circular diffuser screen includes multiple, simultaneously-operated projectors to project the image onto the circular diffuser screen from a plurality of locations, thereby forming the 3D image. The aerogel can use the projection device described as applicable to either the spinning diffusive screen or the circular diffuser screen.Type: GrantFiled: August 30, 2005Date of Patent: February 17, 2009Assignee: California Institute of TechnologyInventors: Frederick Mintz, Tien-Hsin Chao, Nevin Bryant, Peter Tsou
