Appl. No.:

09/879420

Inventors:

David C. Swift - Cortlandt Manor NY
Jon Siragusa - Brooklyn NY
Adam W. Divelbiss - Wappingers Falls NY

Assignee:

Vrex, Inc. - Elmsford NY

International Classification:

G06T 1500

US Classification:

345419

Abstract:

The preferred embodiment addresses the problem of delivering stereoscopic media in electronic form (images, videos, animations, object models, etc. ). First, it provides a single format with independent right and left channels to represent the stereoscopic media. Second, it provides a means of displaying stereoscopic media inside a movable windowed area while eliminating pseudostereo conditions during movement. Third, it provides automatic and manual optimization adjustments (parallax shift adjustment, brightness control, color adjustment, and cross-talk reduction) to the stereoscopic media based on viewing hardware, monitor size, and media content for optimal viewing quality. Fourth, it provides seamless support for monoscopic (2D) viewing modes allowing delivery of said stereoscopic media in a normal 2D viewing mode.

US Classification:

438 30, 349 95, 349 96, 349 98, 349124

Abstract:

The invention is a method for creating a micropolarizer, including providing a first plate having a first and a second surface, providing a second plate having a first and a second surface. Then coating a polyimide on each of the first surface of the two plates followed by rubbing the polyimide coated upon the first surface of the first plate along a predetermined direction and rubbing the polyimide coated upon the first surface of the second plate along a direction having a predetermined angle in relation to the predetermined direction. An alignment process includes aligning the first plate and the second plate having the first surface of the first plate and the first surface of the second plate facing each other thereby creating a space there between. In conclusion there is a filling of a liquid crystal material in the space whereby a cell, or film is created.

International Classification:

G21K004/00

US Classification:

378 41, 378 57

Abstract:

The present invention provides a means to augment or upgrade a traditional single beam 2D x-ray system to produce 3D stereoscopic output. The system utilizes the cross-sectional beam divergence of a single source x-ray unit to generate perspective information. This is achieved by scanning the object twice where the object is shifted parallel to the cross-sectional beam plane between scans. The resulting two scans can be displayed on a 3D stereoscopic viewing system to produce a 3D stereoscopic representation of the object thus revealing all three-depth dimensions. The invention includes a method of converting a 2D x-ray system to a 3D x-ray system requiring no changes to an x-ray generation portion, optics portion or sensing system portion of said 2D x-ray system. The method includes coupling a 3D stereoscopic image processor to a 2D processor and installing a mechanical shift system and coupling said shift system to said 3D stereoscopic image processor and a object carrying device.

International Classification:

G09G005/00

US Classification:

345 11

Abstract:

The invention is an improved kiosk for a 3D display. A clear plastic or transparent band surrounds a μPol based 3D stereo flat panel LCD display system. The radius of the band is designed to provide the optimum viewing distance from all angles.

International Classification:

H04N 13/04

US Classification:

348 58, 348 57, 345419

Abstract:

An intelligent system and process for producing and displaying stereoscopically-multiplexed images of either real or synthetic 3-D objects, for use in realistic stereoscopic viewing thereof. The system comprises a subsystem for acquiring parameters specifying the viewing process of a viewer positioned relative to a display surface associated with a stereoscopic display subsystem. A computer-based subsystem is provided for producing stereoscopically-multiplexed images of either the real or synthetic 3-D objects, using the acquired parameters. The stereoscopically-multiplexed images are on the display surface, for use in realistic stereoscopic viewing of either the real or synthetic 3-D objects, by the viewer.

International Classification:

H04N 13/04

US Classification:

348 52, 348 42, 348 51

Abstract:

The present invention utilizes a new and inexpensive method for stereoscopic demultiplexing from a single computer data source. The invention provides a means to switch the routing of left and right image data, if necessary. Additionally the invention provides for an internal swap of the green data signal between the two channels permitting the device to be used with polarized output projection systems in which the green light output is polarized orthogonally to the red and blue light output.

International Classification:

G06K009/00

US Classification:

382/154000

Abstract:

Methods and systems are described for zooming a stereoscopic image. The image is typically divided into a plurality of regions. A value is defined for each region, such as a minimum parallax value or a function of the minimum parallax value. A zoom area is selected having a boundary intersecting at least one of the regions. The values within the intersected regions are compared to determine a preferred value based on predetermined criteria. The zoom area is shifted by the preferred value or a function of the preferred value.
