Abstract: A multiview image creation system and method create a multiview image from a single view image. Creating a multiview image includes importing a single view image and assigning the single view image to a first multiview image layer of a composite multiview image. Creating a multiview image further includes replicating the single view image into a plurality of view images of the first multiview image layer, converting a depth setting of the first multiview image layer into a plurality of shift values of corresponding view images based on an ordered number of the view images, and shifting the view images of the first multiview image layer according to the corresponding shift values. The plurality of multiview image layers may be automatically rendered in a predefined sequence as the composite multiview image on a multiview display.

Abstract: A light field camera system and method of setting a baseline and a convergence distance of a multiple camera rig employ sample point depths to determine and set values with respect to a three-dimensional (3D) scene. A baseline and a convergence distance of a multiple camera rig is set by determining a plurality of sample point depths representing distances between the multiple camera rig and a plurality of sample points in the 3D scene within a field of view of the multiple camera rig. The convergence distance is set to be an average sample point depth of the plurality of sample point depths. The baseline is then set as a negative inverse of a difference between a minimum sample point depth of the plurality of sample point depths and the convergence distance. The light field camera system includes a multiple camera rig comprising a plurality of cameras.

Abstract: A mode-switchable backlight and privacy display provide narrow-angle emitted light during a first mode and broad-angle emitted light in a second mode, the broad-angle emitted light being a combination of the narrow-angle emitted light and bidirectional emitted light. The mode-switchable backlight includes a first directional backlight and a second directional backlight. The first directional backlight includes an array of narrow-angle emitters configured to provide the narrow-angle emitted light during both of the first mode and second mode, while the second directional backlight includes an array of bidirectional emitters configured to provide the bidirectional emitted light exclusively during the second mode. The mode-switchable privacy display includes an array of light valves configured to modulate the narrow-angle emitted light during the first mode and to modulate broad-angle emitted light during the second mode.

Abstract: A privacy display provides a private image exclusively visible within a viewing cone of a viewbox. The privacy display includes a light guide to guide light, a diffraction grating configured to diffractively couple out a portion of the guided light as diffractively coupled-out light and to direct the diffractively coupled-out light into the viewbox, and a light valve array configured to modulate the diffractively coupled-out light to provide the private image. An extent of the viewbox is determined by a collimation factor of the guided light. A dual-mode privacy display system further includes a broad-angle backlight configured to provide broad-angle light to separately provide a public image visible both inside and outside the viewing cone. The private image may be provided in a privacy mode and the public image may be provided in a public mode of the dual-mode privacy display system.

Abstract: A static multiview display and method of static multiview display operation provide a static multiview image using diffractive gratings to diffractively scatter light from guided light beams having different radial directions provided by a horizontal diffuser. The static multiview display includes a light guide configured to guide the light beams; the horizontal diffuser configured to provide the guided light beams with the different radial directions using light from a directional light source; and a plurality of diffraction gratings configured to scatter out light from the guided light beam plurality as directional light beams representing the static multiview image. The method of static display operation includes providing and diffusing directional light to provide guided light beams having different radial directions, and further scattering out light from the guided light beam as directional light beams representing the static multiview image.

Abstract: A multiview display includes a multiview backlight configured to emit directional light beams configured to converge at points within a convergence plane, and an array of light valves configured to modulate the directional light beams at the convergence plane. A distance between the multiview backlight and the light valve array is configured to be adjustable to shift a corresponding location of the convergence plane relative to the multiview display.

Abstract: A multi-zone backlight and multi-zone multiview display with multiple zones selectively provide broad-angle emitted light corresponding to a two-dimensional (2D) image and directional emitted light corresponding to a multiview image to each zone of the multiple zones. The multi-zone backlight includes broad-angle backlight to provide the broad-angle emitted light and a multiview backlight to provide the directional emitted light. Each of the broad-angle backlight and the multiview backlight is divided into a first zone and a second zone that may be independently activated to provide the broad-angle emitted light and multiview emitted light, respectively. The multi-zone multiview display includes the broad-angle backlight and the multiview backlight and further includes an array of light valves configured to modulate the broad-angle emitted light as a two-dimensional image and the directional emitted light as a multiview image on a zone-by-zone basis.
