[Problem] The present invention provides a stereoscopic image display device, stereoscopic image display method, and a program capable of displaying the display target with a constant size and a constant aspect ratio even when the distance between the stereoscopic image display device and the user changes. [Solution to Problem] The present invention provides a stereoscopic image display device comprising: a display part; an acquisition part configured to acquire an observation viewing distance that is a viewing distance from the display part to a user; and an adjustment part configured to adjust a display state of a display image based on a reference viewing distance and the observation viewing distance, wherein the display part is configured to display a stereoscopic image based on the display state.

A volumetric display capable of high-speed image presentation includes a resonance-type liquid lens having a focal length that is periodically adjusted using resonance of a liquid. An image projector projects an image toward a viewpoint position of a user via the resonance-type liquid lens. Further, the image projector projects an image toward the viewpoint position within a shorter time period than one-tenth of a variation cycle of the focal length. The image projector includes an LED and a DMD, for example.

A stereoscopic image display device includes a display 11 divided into sections 13 in each of which displayed are small images 12a to 12d each having a plurality of minute images 14, a shutter panel 16 disposed in front of the display 11 and including first mechanical shutters 17, which are arranged side by side in units of the minute image 14 and time-divisionally divide each section 13 per each of the small images 12a to 12d by switching on and off in units of the minute image 14, and an image forming panel 23 including image forming means 24 arranged side by side for forming an image from light rays from each of the small images 12a to 12d passing through the first mechanical shutters 17 when the first mechanical shutters 17 are on.

A light-source module includes a light-source unit, a first projection lens, a first lens, a mirror wheel, a first light-guiding unit, a second light-guiding unit, and a second projection lens. The first projection lens has an entrance pupil. The light beam provided by the light-source unit can pass through the first projection lens via the entrance pupil and then is guided to the mirror wheel. With the rotation of the mirror wheel, when the light beam passes through the mirror wheel, it becomes a transmission light beam. At different time, when the light beam is reflected by the mirror wheel, it becomes a reflection light beam. The second projection lens has a first exit pupil and a second exit pupil, in which the transmission light beam and the reflection light beam pass through the second projection lens via the first exit pupil and the second exit pupil, respectively.

A portable theater includes a plurality of individual panels assembled together to form a theater enclosure, a plurality of audience seats installed within the assembled theater enclosure, and a projection screen mounted within the assembled theater enclosure. The projection screen has a partial toroidal shaped reflective surface configured to reflect, toward the plurality of audience seats, a moving image as projected by a projector.

A system creating an autostereoscopic augmented reality (AR), virtual reality (VR), or other visual display experience involving 3D images, presented to a viewer without glasses or other head-gear. The system includes a projection screen, which includes a reflective surface formed using retroreflective material. The system includes a projection assembly and a beamsplitter, which is disposed between an outlet of the projection assembly and the projection screen. The system includes a physical scenic space facing a lower side of the beamsplitter and a viewing space facing an upper side of the beamsplitter. A controller operates the projector assembly to project left and right eye images toward the projection screen. The left and right eye images are then directed to left and right eye positions so a viewer with eyes positioned at the left and right eye positions perceives a virtual object concurrently with light from the physical scenic space.
