摘要:
A line blanker system for converting a stereoscopic image into a line-blanked stereoscopic image suitable for stereoscopic viewing on a standard non-interleaved display device is provided. The system includes a method for controlling the line blanker. According to the invention, one can enable and disable the line blanker, identify the first line of the image being processed and determine whether the first line is for viewing by the left eye or the right eye of a viewer. In addition, the invention includes a line doubler. The line doubler provides enhanced brightness and resolution by replacing the blanked line with a double of the line immediately adjacent to the blanked line.

The present invention relates to a system and method of viewing pairs of perspective images of 3-D objects (i.e. stereoscopic image pairs) displayed from a CRT display surface in a time-multiplexed or field-sequential manner, and more particularly to a universal method of generating control signals for synchronously changing the optical state of liquid crystal (LC) shutter panels through which the time-multiplexed perspective. images can be sequentially viewed in a substantially flicker-free manner by the left and right eyes of a human viewer, independent of whether the images are displayed on NTSC, PAL, VGA or SVGA styled CRT display devices.

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.

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.
摘要:
A desktop-based stereoscopic projection display system affording high-resolution stereoscopic and peripheral viewing of three-dimensional color imagery over a field of view of at least 180.degree.. The projection volume required by each image projector of the display system is disposed substantially within the overall display volume of the display system, while maximizing the viewing volume within which the viewer is free to move during interactive stereoscopic viewing sessions. The display system utilizes high-resolution image projectors, keystoning correcting optics and projection-beam folding mirrors which are compactly mounted immediately above the upper volume-boundary surface of the overall display volume of the system, in order to permit the use of three-dimensional display structures having footprints and display volumes that are supportable upon desktops and in other viewing environments characterized by spatial restrictions.

摘要:
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.
