Patent number: 5886818Abstract: Image compositing apparatus and methodology for the creation, in a defined volume of three-dimensional space, of a composite organization of plural images/visual phenomena, including at least one projected real image, displayed in formats including (a) front-to-rear, (b) side-by-side and (c) overlapping and intersecting, adjacency. The apparatus incorporates different unique arrangements of visual sources, and optical elements including concave reflectors, beam splitters and image-forming/image-transmissive scrim/screen structures. In one important modification of the system, which does not necessarily require compositing, a projected real image is derived from an image-producing data stream containing three-dimensional image cues selected from the group consisting of shading, occlusion, perspective, motion parallax, size vs. depth, light (chroma value) vs. depth and definition vs. depth.Type: GrantFiled: November 2, 1994Date of Patent: March 23, 1999Assignee: Dimensional Media AssociatesInventors: Susan Kasen Summer, Steve A.

Patent number: 5883695Abstract: Method and apparatus for producing stereoscopic images for motion picture or TV using a single sensor or camera and a single lens. In carrying out the method of the invention, the camera lens is caused to rotate about an axis defined by the optical path of the incoming image rays. The apex of the cone is defined by the object being rendered. The base of the cone is defined by the image sensor portion of the camera and its circular path remains unchanged during an image rendering session. The lens of the camera, on the other hand, travels in a smaller circular path and the circumference of the path of travel of the lens is increased or decreased depending on the distance from the image to the lens and can change during the image rendering session. Apparatus comprises a frame which is driven by an electro mechanical drive mechanism for moving a camera support body through a conical path.Type: GrantFiled: September 19, 1997Date of Patent: March 16, 1999Inventor: Eddie Paul

Patent number: 5556184Abstract: Imaginograph is an image on a screen which is mathematically generalized optical illusion to create psychological three dimensionality. These pictures are the would be "merged images in the brain" produced outside the brain. Rather than creating one picture for the left eye and another for the right, an Imaginograph is already the result of the analyzed signals. Using the property that when one is looking at a flat picture, the brain superimposes the two substantially same images in the left and right eyes and produces the same picture in the brain, Imaginographs are pictures which are formed by superimposing the left and right eye views at the same position as the object of interest in the view, keeping the images of the object of interest in the two pictures in register at all times. The left and right eye views and their projections can be generalized to obtain three dimensional views of non-Euclidean spaces.Type: GrantFiled: April 11, 1994Date of Patent: September 17, 1996Inventor: Rahim Nader-Esfahani

Patent number: 5371627Abstract: A random dot stereogram is formed using a novel method from relatively fine pixels. The "dots" of the stereogram are formed from the pixels in diverse shapes and sizes and are measurably more random in particular respects than dots used in the prior art. The dots are constructed in such a manner that they have a greater range of pixel counts per dot and tend to have more sides and a greater range of size counts than do prior art dots. An apparent three-dimensional image is formed on the dot background by shifting groups of dots, with the amount of the shift determining the apparent height of the group of dots. Superior resolution in the apparent height of the dot groups is obtained by assigning the quantum of movement to be significantly less than the size of the dots. The combination of the increased randomization of the dots and the reduction of the quantum of movement (for example, to 1/300 inch) produces a resolution which was not available using prior art methods.Type: GrantFiled: October 23, 1992Date of Patent: December 6, 1994Assignee: N.E.

Patent number: 5257130Abstract: An apparatus and method for creating real image illusions utilizes a partially transparent scrim positioned between the real image and an optical system which produces the real image from a corresponding real object. When the scrim is illuminated by a light source or projector in front of and at an oblique angle to the scrim, the scrim forms a seemingly solid and non-transparent surface that conceals the optical system from view by an observer. The scrim also protects the optical system from damage and other vandalism, yet it does not distort or interfere with the light rays passing through the scrim to form the real image. The scrim also avoids distracting surface reflections, ghosting and other highlights.Type: GrantFiled: January 30, 1992Date of Patent: October 26, 1993Assignee: The Walt Disney CompanyInventor: Marshall M.

Patent number: 5144344Abstract: The present invention relates to a pair of spectacles for stereoscopic pictures based upon the principle of the Pulfrich effect. The direction in which a moving object is moving in a picture or the moving direction of a video camera is marked on the spectacles for stereoscopic pictures to obtain a correct stereoscopic image, so that the viewer can easily and readily determine which of a darker lens or a lighter lens is applied to which eye. According to the invention, the connecting portions between the front frame and the temples of the spectacles are formed as a pair of hinges which protrude from the inside front frame and are spaced apart from each other so that a space therebetween receives the hinges of a pair of standard glasses worn by a viewer to support the stereoscopic spectacles on the standard glasses with great stability. This also enables the stereoscopic spectacles to be reduced in size so that they may be worn more stably by those who do not wear vision correcting glasses.Type: GrantFiled: May 24, 1990Date of Patent: September 1, 1992Assignee: Sony CorporationInventors: Katsumasa Takahashi, Takuya Nakamaru, Osamu Iino
