A plasma arc tube display is fabricated by arranging a plurality of arc tubes having fluorescent substance layers on the inside and filled with a discharge gas, joining a front substrate and a rear substrate having electrodes to both surfaces of these arranged arc tubes, and interconnecting a plurality of plasma arc tube modules having frames facing the rear substrate with the flexible front substrate interposed therebetween to connect the electrodes installed on the front substrate to each other. Since the plasma arc tube modules can be folded, the plasma arc tube display can be easily transported even if it has a large-sized screen.

A parallax image generator establishes a plurality of projected regions around a display in predetermined intervals and generates a plurality of parallax images having different parallaxes due to being seen from respective points of view. In addition, pixels of the plurality of parallax images occupying the same position are gathered together in a pixel block, and are mapped to rendering memory corresponding to the display. A parallax image display unit displays mapped images in the rendering memory, projects the light from a pixel toward the projected region corresponding to each parallax image per pixel of the plurality of parallax images in each pixel block, and makes a 3-D image observed by positioning both eyes of an observer in adjacent projected regions and projecting the parallax images.

An apparatus for deflecting light of the present invention comprises: (a) at least one pair of transference electrodes arranged facing one another; (b) a drive circuit which applies a voltage among the transference electrodes; and (c) a liquid crystal which is inserted among the transference electrodes, and whose parallel stripes that function as a diffraction grating when the voltage is applied among the transference electrodes are produced at a pitch corresponding to the applied voltage. The light can be scanned if a diffracted light by the apparatus for deflecting light is converted into a scanning light and a voltage value is changed temporally to apply the voltage among the transference electrodes. In a device for reading information, the scanning light is reflected in a bar code and the reflected light is detected by an apparatus for detecting light. In a device for stereoscopic display of the present invention, the apparatus for deflecting light is used as beam deflection means for deflecting the light beamed from a picture element which organizes the pictures of the picture display means.

In a method and apparatus for displaying a stereoscopic image, a plurality of 2-dimensional images having parallaxes in only horizontal directions are obtained and inputted when an object to be displayed is seen from different positions in the horizontal direction. The 2-dimensional image is divided in the vertical direction into 1-dimensional line images which are elongated in the horizontal direction. A phase distribution of a corresponding hologram segment is calculated from the pixels of the line image. The calculated phase distribution is displayed on a hologram forming surface of a phase displaying section using a display. A reproduction light is irradiated and converted into an optical wave front and is further enlarged in the vertical direction, thereby displaying a solid image. The 2-dimensional images are inputted by photographing the object by a plurality of cameras arranged in the horizontal direction. The 2-dimensional images can be also produced by interpolating calculations from two 2-dimensional images which were actually photographed. The 2-dimensional images which are used in the phase calculations are subjected to a process such as enlargement, reduction, or movement of the coordinate position, thereby adjusting the size and position of a solid image.

In a display section, a plurality of pixels of minimum display units to display a hologram phase distribution are arranged to thereby construct a cell to display one pixel of a 2-dimensional image, and cells are further two-dimensionally arranged to thereby construct a display image plane. 2-dimensional image data and hologram phase distribution data from an input section are given to a display data forming section. Corresponding 2-dimensional image data and a hologram phase distribution are displayed in a display region of a display section, thereby producing hologram data for allowing a solid image to be recognized by the optical wave front conversion. A display control section executes a display control for allowing the 2-dimensional image data and hologram data from the display data forming section to be displayed in the display section. The 2-dimensional image data and hologram data are commonly managed and produced by the same data format of the cell unit including the image kind, display region, and display data in the region.
摘要:
A hologram of a virtual object or an object which actually exists is formed and a solid image is displayed. 3-dimensional information of the object to be displayed is divided into regions in the depth direction. Depth images are formed as 2-dimensional images where are seen from a plurality of points which are obtained by finely dividing the hologram forming surface for every region. A phase distribution at the hologram forming surface is calculated from the depth images and displayed on a liquid crystal display or the like as an electronic hologram. A reference light is irradiated onto the display and is converted into an optical wave front, thereby displaying a solid image. When forming a hologram recording medium, a zone image corresponding to each of the finely divided exposure regions of a dry plate is exposed multiple times.

Three-dimensional information for each object structure is used to provide a 2-dimensional plane to obtain a 2-dimensional image. Two-dimensional images by the projection seen from a plurality of points, which were finely divided on a hologram forming surface are formed on the 2-dimensional setting plane. As for an electronic hologram, a phase distribution at the hologram forming surface is calculated from the 2-dimensional images of each figure structure. The calculated phase distribution is displayed on a liquid crystal display or the like. A reference light is irradiated onto the phase distribution and is converted into an optical wave front, thereby displaying a solid image. In case of forming a hologram recording medium, each of the 2-dimensional images of a plurality of structures is multiplexingly exposed and the exposed regions are finely divided on a dry plate.

An image display to display a 2-dimensional image and a beam deflector to deflect the lights from the pixels constructing the image of the image display are provided. The beam deflector is arranged closely in front of the image display. A plurality of 2-dimensional images of different visual directions are sequentially displayed in the image display. The light from each pixel is deflected by the beam deflector synchronously with the display of the 2-dimensional image so that the light from each pixel is directed to the region in which the visual point has been set in order to obtain each image. The switching operation in this instance is executed at a high speed.

In a vehicle seat, a bracket contact member is fixed to a seat back frame and contacts support brackets in an initial use position, to suppress rearward tilting of a head rest with respect to the seat back frame. While suppressing rearward tilting, forward tilting of the head rest with respect to the seat back frame from the initial use position, by inertia force in the event of a rear-end collision of a vehicle, is not suppressed by the contact member.
