Definitions

  • Natural human vision perceives three-dimensional imagery by fusing together two images of the spacial world each simultaneously perceived by a person's right eye and left eye in parallax, from two slightly different, horizontally displaced perspective viewpoints. This was first discovered in the early 1800' s and is known as binocular vision. The discovery has yielded several new art forms utilizing the binocular vision theory, including the stereogram and the stereoscope, invented by Sir Charles Wheatstone in the 1830s. The stereogram and the stereoscope gained widespread popularity with the introduction of photographic stereo pairs and refinements to the stereoscopes. These stereoscopic images, when viewed through a stereoscope, provide a user with a visual medium that approximates the experience of natural human visual perception of three-dimensional space.
  • a stereogram or stereo pair typically consists of two separate stereo images of the same object produced on a flat, planar two-dimensional medium.
  • the two stereo images typically correspond to images as seen by the left eye and right eye.
  • the stereo images are positioned next to each other so that the perspective viewpoints of the images are displaced horizontally by a distance which usually corresponds to the average interocular distance of the left and right eyes .
  • these linticular photos are generally created by condensing small vertical strips of the image into alternating left-eye and right-eye rectangular-shaped images and recording them onto an emulsion.
  • a linticular screen consisting of very narrow cylindrical plastic ripples
  • the user using both eyes, will see two views which show small differences yielding an overall stereoscopic image.
  • linticular prints have significant limitations. Specifically, the ability of the user to see the stereoscopic image correctly is dependent upon the chosen viewing angle. Incorrect angles can cause severe aberrations in the stereoscopic image.
  • U.S. Pat. No. 4,973,087 to Balogh discloses a postcard formed of a single sheet of card stock consisting of two sections.
  • the first section is defined by an opening with at least one transparent window tinted in a first color.
  • the second section contains anaglyphically printed matter in both the first color and at least one other contrasting color.
  • the printed matter is then viewed through the window of the first portion to produce a visual effect.
  • Balogh discusses using the anaglyphic postcard to reveal a hidden solution to a question or puzzle.
  • the anaglyphic device disclosed can not be utilized for viewing stereoscopic images.
  • 5,000,543 to Curtin and U.S. Pat. No. 5,002,363 to Tanaka generally refer to three-dimensional viewers made by folding a single sheet of card stock into three sections.
  • the first section comprises a pair of three- dimensional lenses
  • the second section is of a longitudinal extent substantially equal to the focal length of the lenses
  • the third section comprises at least one pair of stereoscopic images arranged side by side, wherein the second section is held generally normal to the plane of the first section and the third section is held generally parallel to the first section when the viewer is in use.
  • One disadvantage associated with these prior art devices is that, because a large portion of the cardstock is used to the second section in order to position the images at the correct distance from the lenses, each pair of stereoscopic images must be relatively small.
  • One such multi-page format is a book containing pages imprinted with stereoscopic images and accompanying text and a stereoscope, an example of this is "3-D Hollywood".
  • This multi-page format also suffers from several limitations. For example, because the stereoscope is not attached to the book containing the images, the user must determine the correct positioning of the stereoscope with respect to the eyes and with respect to the stereoscopic images. This correct positioning is often difficult to achieve, especially for a user unfamiliar with stereographs. Furthermore, even if the user positions the stereoscope to produce the three- dimensional effect, the effect will likely be seen with aberrations, because the user is unlikely to have achieved the precise positioning.
  • U.S. Pat. No. 3,462,210 to Monzali generally comprises a book with pages of stereoscopic images and accompanying text, and a stereoscope.
  • the stereoscope is of box-type construction, requiring a series of complicated steps to assemble.
  • the page upon which it is located must be removed from the book and inserted into a space provided in the viewer. Thus several steps are needed to view each sequential pair of stereoscopic images in the book.
  • box-type viewer is not attached to the book and must be disassembled each time the user places the viewer within the book for storage.
  • each device comprises a pivotal shell casing containing multiple pages of stereoscopic images and a stereoscope, wherein the pages and the stereoscope are pivotally connected to the casing.
  • the pages containing the stereoscopic images nor the stereoscope is self supporting, and thus the user must use both hands to maintain the device in the viewing configuration and to operate the device.
  • the configuration of the device requires modification of the device each time the user reads the accompanying text and then views the images through the stereoscope . Accordingly, several objects of the present invention are to:
  • the present invention accomplishes the above objectives more effectively than the prior art because of several distinct advantages. Specifically, the present invention:
  • (b) works for images of various formats such as large pictures and panoramic views aligned vertically or horizontally;
  • (c) works with stereoscopes that produce the three- dimensional effect with the standard parallel technique as well as stereoscopes that utilize the cross-eyed or over- under techniques; (d) is capable of enabling the user to view multiple pages of text and/or stereoscopic images in succession without the need to reconfigure the device; and
  • (e) can have the ability to interchange stereoscopes, thus enabling stereoscopic images of different formats and properties, i.e. focal lengths, to be viewed correctly with the same device.
  • a device for viewing stereoscopic images generally comprising one or more pairs of stereoscopic images, one or more stereoscopes, stereoscope attachment means, and distance setting means.
  • the stereoscope attachment means may comprise a slot provided by the structure of the stereograph in which the stereoscope may be placed during storage and/or transport of the stereoscopic device.
  • the distance setting means may comprise a string, a rod or a bar, and assists the user in locating the stereoscope such that it is separated from the stereograph by a distance substantially equal to the focal length of the stereoscopic lenses.
  • At least a portion of the distance setting means may be stored inside the slot so that the device is compact while it is in a stored configuration and so as to facilitate transport of stereoscopic device via the mails .
  • the stereoscopic device may be in the form of a postcard for transmittal through the mails without the need for an additional mailing envelope.

As components separate from frame 30, lenses 26, 28 may be of unitary construction or multiple-piece construction and may be made of a material such as glass or plastic. Lenses 26, 28 may be fixably attached to frame 30, for example, by being fixably secured between two layers of material forming frame 30 or by being snap-fitted into recesses surrounding orifices 22, 24.

Abstract

La présente invention concerne un dispositif permettant de visualiser des images stéréoscopiques, lequel comprend une ou plusieurs pages de paires d'images stéréoscopiques, un stéréoscope (20), un moyen (60) de réglage de la distance et un moyen (56) de fixation de stéréoscope. Le moyen de fixation de stéréoscope couple le stéréoscope et/ou le moyen de réglage de la distance au stéréogramme durant le stockage et/ou le transport du dispositif stéréoscopique. Le moyen de réglage de la distance permet de placer le stéréoscope à une distance prédéterminée des images, la distance prédéterminée étant sensiblement égale à la distance focale des lentilles du stéréoscope, et il permet par conséquent à l'utilisateur d'obtenir un effet stéréoscopique tridimensionnel selon un procédé simple, en regardant les images à travers les lentilles. Le dispositif stéréoscopique peut se présenter sous la forme d'une carte postale, d'une carte de voeux ou d'un livre, ou bien il peut être placé dans un dépliant, une brochure, un magazine ou dans d'autres publications similaires à des fins publicitaires, éducatives ou récréatives.
