    Abstract: The volumetric 3D display system of this invention applies a moving display panel that sweeps a display space. The full volume swept by the active screen is used as display space. A 3D image to be displayed is first processed into slices of image data based on an orthogonal 3D grid structure. The slice data are then converted into image frames to be displayed on the active screen by mapping the location indices in the orthogonal 3D grid to the location indices on the moving screen. The preferred method of displaying an image frame is to convert each image frame into a number of “image shots” and then display those image shots in sequence. An image shot comprises a number of simple orthogonal patterns aligned in vertical or horizontal directions. Combination of a number of image shots approximates the corresponding image frame.

Input events are assigned to the windows responsive to whether they are spatial or non-spatial. Spatial events are assigned to the window surrounding the event or cursor where a policy resolves situations where more than one window surrounds the cursor. Non-spatial events are assigned to the active or working window.

    Abstract: A stereoscopic image display method capable of stereoscopic display of a photographed image. One two-dimensional image is selected, and one pixel capable of being viewed from a corresponding viewpoint position is selected from a plurality of pixels. A virtual surface with the selected two-dimensional image pasted thereon is assumed, and the virtual surface is arranged so that an image center point of the two-dimensional image corresponding to a center of an object coincides with a center of a display surface. Next, a virtual extension that extends from the viewpoint position to the virtual surface through the selected pixel is assumed. A color on the two-dimensional image assumed to have been pasted on the virtual surface, corresponding to a point of intersection between the virtual extension and the virtual surface is determined as a display color of the pixel positioned in a direction extending from the pixel to the viewpoint position.

  • Patent number: 7898502
    Abstract: Variation of the wavelength of the light emitted from a light source is reduced by a wavelength variation reduction mechanism. Hence, wavelength deviation of the intensity peak of the light emitted from the light source from the diffraction-efficiency peak of a hologram optical element is reduced. Thus, even when a high-brightness light source is used, the light emitted therefrom can be diffracted with the hologram optical element efficiently. Moreover, the heat generated by the light source is efficiently rejected through the surface of a land portion of a flexible printed circuit, is then, via an insulating layer of the flexible printed circuit, efficiently absorbed through the surface of a heat absorbing member, and is then, via a shield conductor, led out of a casing, so as to be thereby expelled.
