A stereoscopic image display apparatus has a light source for emitting patterned light in a predetermined shape, an optical system having horizontal optical action and vertical optical action different from each other, and a display device. The display device displays a stripe image obtained by alternating stripe pixels from a parallax image for the right eye and stripe pixels from a parallax image for the left eye in a predetermined order. The patterned light is provided with directivity by the optical system to irradiate the stripe image. The light is separated into two areas, so as to permit an observer to visually recognize the stripe image as a stereoscopic image. In the stereoscopic image display apparatus, a difference DH between a horizontal pitch Hi of the patterned light and a horizontal pixel pitch Hd of the display device is not less than a predetermined value.

A stereoscopic image display apparatus for causing an observer to observe a stereoscopic image, includes a light source for illuminating, with a surface illuminant, a mask substrate on which a mask pattern including aperture portions and shielding portions arranged in a checkerboard pattern is formed, a vertical cylindrical lens array including vertical cylindrical lenses each having a generatrix in a vertical direction, and a transmission type display device for displaying an image on scanning lines. Right stripe pixels and left stripe pixels are alternately arranged in a predetermined order to form one image, thereby displaying a horizontal stripe image on a display surface of the display device, and light beams emitted from the light source, to which directivity is given by the vertical cylindrical lens array, irradiate the horizontal stripe image. The light beams are separately condensed on at least two regions to make the observer to see the horizontal stripe image as a stereoscopic image, and a horizontal width of a pair of an aperture portion and a shielding portion arranged on the mask pattern in a horizontal direction is set to be not less than twice a horizontal pixel size of the display device.

Parallax images corresponding to a plurality of different view points are each divided into predetermined stripe images, a synthetic parallax image is synthesized from the stripe images, and display light, from stripe images corresponding to one view point of the synthetic parallax image on the image display element displaying the synthetic parallax image, is guided to a mask member having a mask pattern with predetermined openings and shields by a second optical system placed in front of the image display element. The display light passing through the openings of the mask member is condensed to a position corresponding to the view point on an observation surface a predetermined distance apart, by a first optical system, whereby an observer is permitted to stereoscopically observe image information displayed on the image display element.

This invention has as its object to provide a viewpoint detection apparatus and method, which can assure high-speed processing, high precision, and high tracking performance with a simple arrangement while suppressing adverse influences on the human body, and a stereoscopic image display apparatus using the same. The viewpoint position detection apparatus of this invention has an image sensing unit (1) and a viewpoint detection unit (2). The image sensing unit has a visible image sensing section (11) and infrared image sensing section (12). A pupil position detection processing section (24) detects the pupil position from an infrared image, and a template generation section (23) generates templates for a visible image using the pupil position obtained from the infrared image. A pattern matching discrimination section (22) executes pattern matching of a visible image. The infrared ray irradiation time upon capturing an infrared image can be minimized, and the load on processes can be reduced since pupil position information detected from the infrared image is used upon generating templates. An image display unit (3) as a stereoscopic image display apparatus is connected to the viewpoint position detection apparatus, and viewpoint position information is supplied to the image display unit, thus constructing a stereoscopic image display system having a broad stereovision range for the observer.

A color image reading apparatus includes a multiple-line sensor in which a plurality of one-dimensional sensor arrays are arranged on a single substrate, a projection optical system for projecting a subject on the sensor, and a color separator disposed in an optical path between the projection optical system and the sensor, for color-separating light from the subject into a plurality of color beams. The color separator includes a volume hologram and an optical interference film.
摘要:
A stereoscopic image display apparatus in accordance with the present invention solves a problem with a conventional multi-view stereoscopic image display apparatus in that the resolution of each parallax image deteriorates as the number of provided parallax images increases. The inventive stereoscopic image display apparatus forms a plurality of images for right and left eyes in observation regions for the observer's right and left eyes to enable the observer to obtain a stereoscopic view. At the same time, a region where no images are formed is provided between the right eye and left eye observation regions, because no actual observation is carried out in the region. This makes it possible to reduce the total number of parallax images without changing the number of actually observed parallax images, thus achieving a higher resolution of each parallax image actually observed.

A magneto-optical disk according to the present invention has a transmission directory and a reception directory. An image to be transmitted is stored under the transmission directory as a single file, while a received image is stored under the reception directory as a single file. The operator designates a desired file stored under each of the directories for printing or transmission.
摘要:
An optical information recording medium includes a base, a reflecting layer formed on the base, a second layer formed parallel to the first reflecting layer at a predetermined distance from the same, and a recording layer formed between the first and second reflecting layers. The recording layer has an array of a plurality of cells having different refractive indices which are changed when irradiated with a light beam. The intensity of the light beam is modulated according to information. Irradiating the recording layer with the modulated light beam causes changes in the refractive index according to the intensity of the light beam. In another aspect, the wavelength of the light beam is changed within a predetermined range including at least one wavelength at which multiple interference occurs between the first and second reflecting layers with respect to each cell. The wavelength of light which has effective reflecting multiple interference is detected. The information recorded in the cell is reproduced in accordance with the wavelength detected. The medium may be used in an apparatus for recording and reproducing information.
