    摘要： The invention is based upon the use of the characteristic of LCD screen which offer the possibility of directing the visibility angle of said screens as a function of the voltage applied. By directing said angle towards one eye or the other of the viewer alternatingly, as a function of previously recorded stereoscopic images and at a sufficiently high rate so that the viewer cannot perceive discontinuities, a tri-dimensional effect in the image received by said viewer is obtained. The block diagram of one of the invention includes an image generating system 2 connected to an LCD screen 1 and to an image synchronization block 3 which is connected to an angle generator system 4, the latter providing the necessary voltages to the screen 1 in order to direct the image from the screen to one or the other eye of the viewer.

    摘要： Improvements in the production means for dodecahedral imaging are described, to define a simple, flexible and efficient strategy for the creation of extremely wide images. Improvements in production technology include lenses and optical mounts that enable automatic alignment of film and video cameras and other imaging devices to cover multiple fields of view equal to one, two or three dodecahedral pentagons. Three double-pentagon formats, X, P and O, are described in detail, the X format producing an even hemispherical division and a full spherical view, and the P format producing simplified coverage of most of a sphere and ease of use for stereoscopic effects, and the O based on the combination of the dodecahedron and the octahedron. A triple-pentagon T format based on the use of the tetrahedron is also described, along with crisscross optics and temporal offset mounts to minimize parallax differences between the separate camera views. Standard cropping mattes for dodecahedral images are given, and compressed storage methods are suggested for a more efficient distribution of dodecahedral images in a variety of media.

    摘要： A Method and apparatus is provided for producing and displaying pairs of spectrally-multiplexed gray-scale or color images of 3-D scenery for use in stereoscopic viewing thereof. In one illustrative embodiment of the present invention, pairs of spectrally-multiplexed color images of 3-D scenery are produced using a camera system records left and right color perspective images thereof and optically processes the spectral components thereof. In another illustrative embodiment of the present invention, pairs of spectrally-multiplexed color images of 3-D imagery are produced within a computer-based system which generates left and right perspective images thereof using computer graphic processes, and processes the pixel data thereof using pixel-data processing methods of the present invention. Thereafter, produced pairs of spectrally-multiplexed images can be recorded on diverse recording mediums, and accessed by the display system of the present invention for real-time display on diverse display surfaces including, for example, flat-panel liquid-crystal display (LCD) surfaces, CRT display surfaces, projection display screen surfaces, and electro-luminescent panel display surfaces. In the various illustrative embodiments of the display system, stereoscopic viewing of 3-D imagery is facilitated by wearing electrically passive or electrically-active light polarizing spectacles during the image display process of the present invention.
