A three-dimensional imaging system and method are provided. The three-dimensional imaging system includes a suspension force field generator, a projection module, and a controller. The suspension force field generator generates a suspension force field to suspend a plurality of scattering particles used for scattering incident light and distribute the scattering particles on a projection plane. The projection module projects an image on the projection plane. The controller is coupled to the suspension force field generator and the projection module, controls the suspension force field generator to change the suspension force field so that the projection plane where the scattering particles are distributed moves in a display space, extracts a slice plane image that matches a position of the projection plane from multiple slice plane images sliced from a three-dimensional stereoscopic image, and controls the projection module to project the extracted slice plane image to the projection plane.

An apparatus comprising of a device to enclose a durable, data collecting camera in an upright position, as to be put into subterranean environment, such as a manhole, and utilizing sensors and lights to detail the information of the manhole which it is lowered into. It is attached to a metal arm that may be connected either to an automobile or tripod for stability. An application may be used to view this data and the camera itself has the ability to move 360 degrees while attached to a metal arm. This ensures the camera is kept in an upright position, which is particularly useful while using the Matterport Pro 1/Pro 2 cameras.

The terminal device includes an identification information output part configured to output identification information representing first video data, which is generated from an original video, to the video data distribution device, and a video acquisition part configured to acquire second video data, which is generated from the original video and different from the first video data, from the video data distribution device. The video data distribution device includes an identification information acquisition part configured to acquire the identification information from the terminal device, and a video output part configured to output the second video data to the terminal device based on the identification information.

A wagering gaming apparatus is provided, comprising a 3-dimensional (3D) display device configured to create for a player a visual illusion of a 3D scene for a wagering game, the 3D scene having perceived depth in a z-direction perpendicular to a physical screen having width in an x-direction and height in a y-direction; one or more sensor devices configured to sense a physical location of one or more anatomical features of the player; at least one processor; and at least one non-transitory processor-readable storage medium storing processor-executable instructions. The processor-executable instructions, when executed by the at least one processor, cause the at least one processor to perform various adjustments regarding the 3D scene based on the sensed physical location of an anatomical feature of the player.

The invention features techniques for presenting more than one perspective views to each eye of the viewer, through generating viewing zones with an interval smaller than the diameter of the viewer's pupil by display panel/grating pair/pairs. In the first method, the arraying direction of the small-interval viewing zones is designed having an appropriate small inclination angle to the line connecting the viewer's two pupils, so as to cover each eye with more than one viewing zones which are different with each other. In the extreme case, 4 small-interval viewing zones can implement 3D display with two views for each eye. This is absolutely different with existing grating-based 3D display, which aligns viewing zones along the direction with a small angle (</4) to the line connecting the viewer's two pupils and thus a rather large number of small-interval viewing zone is needed for covering the viewer's two eyes.

A system that incorporates teachings of the present disclosure may include, for example, a non-transitory computer-readable storage medium having computer instructions to detect a first position of a viewing apparatus, wherein the viewing apparatus enables viewing of media programs, obtain a media program in a first viewing perspective that conforms to the first position, present the media program with the first viewing perspective for viewing by way of the viewing apparatus, and transmit to the viewing apparatus a first audio signal corresponding to the first viewing perspective. The storage medium can also have computer instructions to detect that the viewing apparatus has moved to a second position, obtain the media program in a second viewing perspective according to the second position, and present the media program with the second viewing perspective for viewing by way of the viewing apparatus. Other embodiments are disclosed and contemplated.

A display device comprises a display panel (24), a light blocking arrangement for selectively blocking light which is directed to a lateral output direction from the display panel and an array of lenses (27). The display has a privacy mode in which the light blocking arrangement blocks laterally directed light output from the display device and a public mode in which the light blocking arrangement allows light to pass which is directed to a lateral output direction. The light blocking arrangement comprises a stack of layers (80), each layer comprising a pattern of light blocking arrangement portions of two different types (90,92) such that in the stack of layers, the portions align to form light blocking members, each light blocking member being aligned with an respective lens. The repeating pattern of the light blocking members has a pitch which is double the lens pitch. This enables the light blocking arrangement to be manufactured more easily.

An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources by waveguide facets and rear reflector images in cooperation. Viewing windows may be provided at first and second different window planes to improve uniformity in a lateral direction. Further, stray light may be reduced by inner and outer portions of reflective facets with different inclinations for the rear reflector.
