Abstract: An image display apparatus includes a stereoscopic image display apparatus configured to display a stereoscopically visible image, and a planar image display apparatus configured to display a planar image. An adjustment section of the image display apparatus adjusts relative positions, relative sizes, and relative rotations of a left-eye image taken by a left-eye image imaging section and a right-eye image taken by a right-eye image imaging section. The adjusted left-eye image and the adjusted right-eye image are viewed by the left eye and the right eye of the user, respectively, thereby displaying the stereoscopic image on the stereoscopic image display apparatus. The adjusted left-eye image and the adjusted right-eye image are made semi-transparent and superimposed one on the other, and thus a resulting superimposed planar image is displayed on the planar image display apparatus.

Abstract: The present invention discloses a stereoscopic image display system and a method of controlling the same. An eye tracking module locates current 3D spatial positions of the viewer's eyes, and generates the information of both left and right eyes' current 3D spatial positions. A control module controls a display device that can alter the direction of the light outputted, and outputs images on the display device in time multiplex mode. The light containing the left eye image is outputted to the position of left eye instead of right eye at one time point, and the light containing the right eye image is outputted to the position of right eye instead of left eye at another time point, so that a stereoscopic image is perceived according to the parallax theory. The present invention enlarges the visual range of stereoscopic image and achieves a better stereoscopic image visual experience for viewers.

Abstract: At least one of right and left image display apparatuses is provided with an optical axis adjustment mechanism. The optical axis adjustment mechanism changes relative positional relationship between an image displayed on a display device and an ocular optical system in a direction intersecting an optical axis to thereby adjust an angle formed by a pair of right and left optical axes. In this condition, a light source is so arranged as to be substantially conjugate with an optical pupil. The optical axis adjustment mechanism changes the positional relationship described above without changing a position of the optical pupil relative to the ocular optical system. This permits, even when the apparatus is originally designed such that light intensity is high at a designed optical pupil position, achieving the light intensity at this optical pupil position even after optical axis adjustment.

Abstract: Systems and methods for generating a true 3-D display, where each of a viewer's eyes not only sees a different scene, but the scene changes continuously as the viewer moves his/her head or change his/her position from one angular location to another angular location with respect to the display screen. In one embodiment, a system comprises a set of 2-D image projectors and a display screen. The 2-D image projectors are configured to project individual 2-D images substantially in focus on the display screen. The display screen then diffuses (or reflects) each pixel from each of the 2-D images into a small angular slice. This enables the viewer observing the display screen to see a different one of the 2-D images with each eye. Further, the image seen by each eye varies as the viewer moves his or her head with respect to the display screen.

Abstract: A surround-vision display system with a very high visual dynamic range is made possible by distributing a limited number of LED's on the inside of a drum and then spinning that drum around a user. The pixel information for each horizontal position in space is sent to each corresponding LED it visits that position. The LED's are arranged in a grid on a panel tile, and the panel tile is tilted slightly, e.g., at 1.1-degrees. The result is each panel tile presents a continuous vertical stripe in the picture frame as all its LED's are swept by in the drum motion. Several panel tiles stacked vertically inside the drum all contribute to the whole height of the picture frame, e.g., several feet. The entire inside circumference of the drum is populated with the LED panel tiles to keep frame refresh rates up to avoid flicker while keeping drum rotation speeds down to reasonable levels. Thus even though the LED's and drum are moving, the image projected appears to be relatively stationary.

Abstract: In a system in which images having parallax data, and which are made up of plural images containing the parallax information are processed with viewing point conversion, and the resulting new images having parallax data are used, as in a system of generating a holographic stereogram, a unit for generating the images having parallax data is to be independent from other unit or units. To this end, the information necessary to perform viewing point conversion processing of converting the viewing point for an object is attached to images having parallax data when the images having parallax data have been produced. When the images having parallax data is exchanged between the unit for generating the images having parallax data and other unit or units, the exchanged images having parallax data need to be those to which the information has been attached.

Abstract: The invention relates to a stereoscopic recording and display system, preferably having an autostereoscopic display system, wherein the position of the observer (especially the distance of the observer from the display system) is determined with a head tracking system and the convergence angle between the two cameras of the recording system is changed in dependence upon the distance of the observer from the display system in such a manner that, for an approach of the observer toward the system, the optical axes of both cameras are greatly convergent and, for a distancing of the observer from the display, the optical axes of both cameras are only slightly convergent. Simultaneously, the cameras are always focussed onto the intercept point of the optical axes of both cameras.

Abstract: The invention is used with a display (10) of a left and right stereoscopic images in adjacent side-by-side array on a two-dimensional imaging surface such as the screen of a computer monitor or television. The left and right images (L and R) are rotated by 90 degrees in opposite directions from their normal upright orientations. A viewing device which includes a right pair of mirrors (2 and 4) and a left pair of mirrors (1 and 3) is placed between the viewer and the display. The mirrors are oriented at fixed and predetermined angular relationship to deflect the lines of sight from the viewer's eyes to the respective right and left images, and to rotate them by 90 degrees. As a result, the users left and right eyes see upright versions of the left and right images, respectively, creating a wide-field stereoscopic illusion of the images.

Abstract: An automatic viewer for half-frame stereoprints includes a base with a pair of lenses for stereoscopic viewing mounted thereon. The base has a kicking foot and picking detent projecting therethrough for engaging openings in a carrier deck upon which the half-frame stereoprints are pivotally mounted. A control mechanism utilizes cams to coordinate movement of the kicking foot and picking detent to index the carrier deck across the base so that the photoprints may be viewed individually. The carrier deck has two rows of openings for receiving the kicker foot, allowing the viewer to advance the carrier deck from either end presenting a first set of photoprints for viewing when advancing from one end and a second set of photoprints for viewing when advanced from the opposite end. The carrier deck may be stored with other carrier decks in a binder.
