Abstract: A three-dimensional display apparatus is provided with an optical element including optical apertures arranged opposite a display module and in association with the parallax images. The optical apertures cause the parallax images to be displayed in a near-side region closer to an observer, while causing a three-dimensional image to be displayed in a far-side region located opposite the observer with respect to the display module. When a smooth three-dimensional image is to be displayed in the near-side region, the optical gap between the optical element and the display surface is set longer than a reference distance depending on the position of the three-dimensional image. In order to display a smooth three-dimensional image in the far-side region, the observer sets the optical gap shorter than the reference distance depending on the position of the three-dimensional image.

Abstract: An apparatus includes a stereoscopic display region calculator calculating a stereoscopic display region to reproduce a three-dimensional positional relationship in image data displayed on a stereoscopic display device, based on two-dimensional or three-dimensional image data, a position of a target of regard of a virtual camera set in processing of rendering the image data, and orientations of the light beams output from the stereoscopic display device. The apparatus also includes an image processor performing image processing on image data outside a region representing the outside of the stereoscopic display region calculated by the stereoscopic display region calculator. The image processing is different from image processing on image data inside a region representing the inside of the stereoscopic display region. The apparatus also includes an image generator generating stereoscopic display image data from the two-dimensional or three-dimensional image data after processed by the image processor.

The unit has pixels arranged in a matrix form, which are groped into a first group and second groups to display two-dimensional image information constituting elemental images, the image information being obtained from different directions. The optical filter has a first optical opening opposed to the first pixel group and second optical openings opposed to corresponding one of the second pixel groups. The center of the first pixel group is coincident with the axis of the first opening, each center of the second pixel groups is deviated from corresponding one of the second opening axe, and the deviation is gradually increased depending on a distance between the first and the second pixel group centers. The light rays are directed to a reference plane from the first and second pixel groups through the first and second opening axes.

Abstract: A three-dimensional image display apparatus displays element images each composed of a set of parallax component images. An exit pupil array is located opposite the display surface. Exit pupils of the array correspond to the respective element images. The horizontal pitch of the exit pupils or an integral multiple of the horizontal pitch is set equal or slightly smaller than an integral multiple of the horizontal pitch of pixels. The parallax component images are oriented in different directions via the exit pupil. Principal beams from the parallax component images via the exit pupils are emitted substantially parallel to one another. The element image contains substantially the same parallax image component in two pixel areas in which two adjacent parallax image components are otherwise displayed. The same parallax image component is oriented in different directions via the corresponding exit pupil.

The average value of the horizontal pitch of element images displayed in the display section is specified to be equal to or greater than natural number m times as large as a pixel horizontal pitch (m<n). The horizontal pitch of the light beam control elemental is specified to be equal to or smaller than natural number m times as large as the pixel horizontal pitch.

Abstract: A three-dimensional-image display system generates a first physical-calculation model generator that expresses a real object, based on both position/posture information expressing a position and posture of the real object, and attribute information expressing attribute of the real object. The three-dimensional-image display system displays a three-dimensional image within a display space, based on a calculation result of the interaction between the first physical-calculation model and a second physical-calculation model expressing a virtual external environment of the real object within the display space.
