摘要： A convertible 2D/3D autostereoscopic display includes of an electronically controllable display screen for displaying two dimensional images thereon and a permanently mounted first lens sheet for projecting 3D autostereoscopic images in a region of space in front of the display. Another lens sheet is pivotally attached to the display to allow it to be swung into and out of physical optical engagement with the first lens sheet. The lens sheets each have complimentary physical structure and optical properties such that when the lens sheets are engaged, the combined lens sheets have a substantially negligible effect on the two dimensional screen image; while disengagement of the lens sheets resumes the display to the 3D autostereoscopic display mode. Complimentary alignment structure is also provided in corresponding non-lens regions of the lens sheets for aligning the respective lenslets when the sheets are engaged. Conventional latches are also provided to secure the lens sheets when they are engaged. In another embodiment, a lens sheet is selectively engageable with a 2D display to form 3D autostereoscopic images when in a closed position and allow 2D viewing when in an open position.

摘要： The stereoscopic CG image generating apparatus and a stereoscopic TV apparatus, has a projection transformation section which, based on three-dimensional structural information describing a three-dimensional shape of an object, generates a plurality of two-dimensional projection models as viewed from a plurality of viewpoints, a distance information extraction section which generates a camera-to-object distance information used for calculations in the projection transformation section, and a camera parameter determining section which, based on the output of the distance information extraction section, the screen size of a stereoscopic image display device for displaying finally generated two-dimensional projection models, and a viewer's viewing distance, determines camera parameters so that stereoscopic CG images will be brought within the viewer's binocular fusional range.

摘要： Techniques for converting a two-dimensional motion picture into a three dimensional stereo motion picture are disclosed. Wire frames of objects in the motion picture are constructed using the frames of the two-dimensional motion picture, substituted for the two dimensional view of the object, photorealistically rendered and stereo views generated of the rendered wireframes to create stereo views of the scenes of the original motion picture. Key frame sequences can be generated in stereo automatically from stereo set up of the key frame.

摘要： A rolling loop motion picture projector is convertible for projecting images either from a 2-D film strip or from a 3-D film strip. The film is advanced through the same incremental amount irrespective of whether a 2-D film of a 3-D film is being projected. The projector has a single central aperture for projecting 2-D images and respective 3-D images on opposite sides of the central aperture. The images on the 3-D film strip are anamorphically compressed in the direction of film travel by a factor of two and the 3-D apertures are correspondingly sized. Projection lenses associated with the 3-D apertures decompress the images so that images of comparable size appear on the screen irrespective of whether a 2-D film or a 3-D film is being shown.

摘要： A stereoscopic remote viewing system includes a pair of spaced apart cameras mounted on a platform which is movable along a semicircular support track for azimuth aiming of the cameras. The track is pivotable about a diametric axis for elevation aiming of the cameras. The cameras are connected through selection switches to a head worn video display unit having a pair of cathode ray tubes (CRT's) mounted therein. Lenses and mirrors are positioned to project the images reproduced by the CRT's indirectly into the eyes of a viewer. A digital computer is connected through the selection switches and is employed for the storage and retrieval of texts and graphic information related to the operations viewed with the system.

摘要： An OLED display panel, a display device, and a display system. The OLED display panel comprises a base plate, first OLED display elements arranged in an array on a side of the base plate, and a first photochromic layer arranged on a side of the first OLED display elements. The first photochromic layer comprises first stripe shaped photochromic bodies and first stripe shaped openings arranged periodically and alternately, and is switchable between a transparent state and an opaque state. When the first photochromic layer stays in the opaque state, the first photochromic layer enables the OLED display panel to realize 3D display on the side where the first photochromic layer is arranged. 2D and 3D display modes are realized on a side of the display panel, which improves user experience and has a low cost.
