    摘要: Several different methods alone or in combination can be used to reduce image jump or stutter. The image plane on which the original image is taken can be mechanically or electronically rotated about a point of rotation in the scene. The number of original images which are viewed could be increased by interpolation. The subtended viewing angle of the viewpoints can be reduced and viewpoints within the subtended viewing angle can be increased by interpolation. Reduced subtended viewing angle images can be created for each eye. The depth of focus of the images can be changed by identifying the images that jump and blurring the images outside the area of interest. The original images can be processed to move the image plane further back from the objects in the scene. Some of the images ordinarily existing between the right and left eye perspectives can be eliminated. The objects in the background of the scene being photographed can be identified and shifted forward in the scene. The highest detail volume of the images can be identified and the images can be processed to rotate around the volume. The highest detail area can be identified and the original images processed to displace the images to minimize the movement of the highest detail area. The original images can be viewed and a point within each image identified to align the point from view to view using a linear or other transformation.

    摘要: A display concept designed to interface with source material from a computer, video recorder or video camera. The interface to a computer generates a series of images that are separate viewpoints of a desired scene to be viewed in three dimensions. The images are based upon a horizontal translation of viewpoints. In the case of a video camera, the interface captures video images from multiple viewpoints and delivers these images in a successive manner to a location at which they can be viewed. The camera requires a single lens and sensor instead of multiple lenses. In the video recorder case, an interface stores images from a computer or video camera and plays back images in the proper sequence for the display. A display system can also operate as a film recorder to provide hard copy, three-dimensional images. A computer, video recorder or video camera thus provides images to a surface which can be viewed and which can present two-dimensional images which are changeable into three-dimensional images. In this way, the output from a computer, video recorder or a video camera can be used to store images and to play back the images in the proper sequence for a three-dimensional display.

    摘要: A three-dimensional image display device comprises a screen shutter unit, a shutter control unit, a display unit, and a display control unit. The screen shutter unit comprises a plurality of long and narrow shutters capable of passing and intercepting light rays. Each of the shutters is positioned vertically and arranged horizontally to each other at equal intervals. The shutter control unit selects shutters from the plurality of shutters at predetermined intervals as long slits to pass light rays through, and moves entire slits horizontally at predetermined time intervals. The display unit displays each image corresponding to each slit on an image display screen provided at a predetermined distance from an arrangement of the shutters. The display control unit displays as images corresponding to respective slits the images obtained by projecting a three-dimensional image to be displayed on the image display screen through the slits synchronously with a moving timing of the slits controlled by the shutter control unit. The images are displayed on respective positions on the image display screen corresponding to respective slits. A part of the image displayed on the image display screen corresponding to the slits is selected through the slits and reaches the viewer's eyes, thereby allowing the viewer to recognize the three-dimensional image.

    摘要: A three-dimensional display apparatus includes a liquid crystal panel 1 for displaying a discrete Fourier transformed image and a slit panel 2 having a convex lens function in a horizontal direction and a plurality of slits 3 arranged in a zig-zag manner, which is disposed in front of the liquid crystal panel 1. Since a spatial image is generated by such a configuration, a wide viewing region can be obtained. Since the number of slits positioned in the horizontal direction is increased as that of a slit pattern of a conventional slit array, the deterioration of resolution in the horizontal direction is reduced. Furthermore, since the slits are arranged in a zig-zag manner, the area of each light-shielding portion between sampling positions is reduced, thereby preventing an optical means from obstructing the observation of images.
