An autostereogram is a single-image stereogram (SIS), designed to create the visual illusion of a three-dimensional (3D) scene from a two-dimensional image. In order to perceive 3D shapes in these autostereograms, one must overcome the normally automatic coordination between accommodation (focus) and horizontal vergence (angle of one's eyes). The illusion is one of depth perception and involves stereopsis: depth perception arising from the different perspective each eye has of a three-dimensional scene, called binocular parallax.

A neutralizing sheet for an autostereoscopic image viewing system. The image viewing system includes a lenticular sheet covering a display screen. The neutralizing sheet including a pliable portion and is movable between a first position and a second position. The pliable portion has a refractive index similar to the lenticular sheet. When pressed into the lenticular sheet to define the first position, the pliable portion deforms to assume the shape of the lenticular sheet. Thus, refraction through the lenticular sheet is neutralized and viewing of planar images is enabled. In the second position, the neutralizing sheet is separated from the lenticular sheet and viewing of stereoscopic images is enabled.

The invention relates to a method of spatial visualization of a scene or an object, in which several views of the scene or object are decomposed into bits of partial information, which are made optically visible by image rendering elements, and in which neighbored image rendering elements emit light of different wavelengths or wavelength ranges, and in which propagation directions for the light are given by means of wavelength filters in such a way that an observer will see predominantly bits of partial information of a first selection of views with one eye and predominantly bits of partial information of a second selection with the other eye. The invention is intended to improve the quality of spatial visualization. In such a method, at least one image rendering element is simultaneously allocated bits of partial information from at least two different views, the allocation being made in such a way that the wavelength of the partial information is always equal to the wavelength, or lies in the wavelength range, of the light emitted by the allocated image rendering element.

Display device
A one-pixel structure of a display panel included in an auto-stereoscopic image display device adopts an in-plane switching mode. Transparent counter electrodes that are not provided in a liquid crystal panel of a normal in-plane switching mode are formed correspondingly to pixel peripheral regions on a second transparent substrate side and, in 3-dimensional image display, a vertical electric field is forcibly generated between the transparent counter electrodes and the comb-shaped electrodes, which causes the liquid crystal molecules to rise to show black display in the pixel peripheral regions. In 2-dimensional image display, meanwhile, the transparent counter electrodes are set to be floating, and the display panel is caused to have a structure substantially equivalent to a structure in which the transparent counter electrodes are not provided, to thereby make the display in pixel peripheral regions identical to the display (brightness) in a pixel main region.

Provided herein are teachings directed to the creation of moiré-based auto-stereoscopic watermarks in rendered images. By choosing different halftone structures, which differ by having different spatial frequencies for each of two delineated partitions in an image, it becomes possible to embed arbitrary binary patterns into printed documents as digital watermarks. The invisible watermarks become moiré auto-stereoscopic images when the prints are viewed through an overlaid transparency “decoder” suitably prepared by virtue of being rendered with a uniform halftone structure having the correct special frequency in relationship with the partition frequencies employed in the printed document.

A single pixel of a video display can display respective individual pixels of multiple views. In other words, a video display can include more views for an autostereoscopic image than the physical pixels of the video display would ordinarily support. The physical pixel is time-multiplexed in that the physical pixel displays a pixel of one view for a given time interval and a view multiplexer deflects the light from the physical pixel by a predetermined angle to make the pixel appear in a location corresponding to the pixel of the view. In another time interval, the physical pixel displays a pixel of a different view and the view multiplexer deflects light from the physical pixel by a different predetermined angle to make the pixel appear in a location corresponding to the pixel of the different view.
