A system and method for manipulating images in a videoconferencing session provides users with a 3-D-like view of one or more presented sites, without the need for 3-D equipment. A plurality of cameras may record a room at a transmitting endpoint, and the receiving endpoint may select one of the received video streams based upon a point of view of a conferee at the receiving endpoint. The conferee at the receiving endpoint will thus experience a 3-D-like view of the presented site.

A display device includes a frame; and a transparent display module in the frame, the transparent display module including a horizontal cross-section including a closed curve and configured to emit light from opposite surfaces thereof.

The present disclosure concerns a method for displaying, on a 2D display device, a content derived from 4D light field data, based on a viewing position of a user. The 4D light field data corresponds to data acquired by either several cameras or by a plenoptic device. The method comprises: obtaining a volume in front of said 2D display device in which no disocclusions are present, said volume being defined according to optical and geometry parameters of an acquisition device that has acquired said 4D light field data, a size of a screen of said 2D display device, and an anchor plane in said content, said anchor plane being perceived as static in case of movement of a user relative to said 2D display device; determining a modified volume from said volume, comprising modifying a size of said volume, for modifying possible movements of a user positioned within the modified volume compared to movements of said user within said volume; providing means for guiding said user within said modified volume according to said viewing position of said user.

Disclosed herein is a method for generating a composite image, including using at least one hardware processor for obtaining at least two images; obtaining composite spatial data that identifies contiguity characteristics of each image of the at least two images; generating a template of the composite image, wherein the template provides a predetermined arrangement of the sections according to the contiguity characteristics identified in the image; sectioning the at least two images into predetermined number of sections according to the template; splicing the sections together according to the template; generating the composite image from the sections of the at least two images; wherein presence of at least one contiguity characteristic in each image generates an composite image that is ambiguous that can trigger an alternating switch in perception and awareness of each image scene and by establishing figure and ground relationship to create a depth illusion.

The technical solution relates to the field of displaying quasi-three-dimensional images. The technical problem addressed by means of the claimed device for generating a quasi-three-dimensional image with a variable depth effect is that of creating a novel design for a device that allows a higher-quality image to be generated. The claimed device for generating a quasi-three-dimensional image with a variable depth effect comprises a housing having a rear wall, on which the device for generating a quasi-three-dimensional image is arranged, and side walls, wherein the housing flares outward from the rear wall and the device for generating a quasi-three-dimensional image is mounted so as to provide for the formation, on the side walls of the housing, of an unilluminated region and an illuminated region with a boundary therebetween.

The perception of a displayed image is altered for viewers moving relative to a display screen, thereby imparting a sense of three-dimensional immersion in the scene being displayed. A display generator generates a scene having foreground and background elements, and a display screen displaying the scene. A sensor detects the position of a viewer relative to the display screen, and a processor is operative to shift the relative position of the foreground and background elements in the displayed scene as a function of viewer position, such that the viewer's perspective of the scene changes as the viewer moves relative to the display screen. The foreground and background elements may be presented in the form of multiple superimposed graphics planes, and/or a camera may be used to record the scene through panning at sequential angles. The system may be used to implement virtual windows, virtual mirrors and other effects.

Disclosed herein is a display system including an image producing unit and an optical system part. The image producing unit produces an image on a display screen by letting a light beam, which eventually forms a virtual image based on the image produced, emerge from the display screen. The optical system part forms a left-eye image and a right-eye image on a user's left and right eyes, respectively, and thereby projects the virtual image toward a user's left and right eyes by reflecting and/or refracting the light beam emerging from the display screen. The optical system part has an image distortion generation factor to make an image distortion of the left-eye image different from an image distortion of the right-eye image.

The perception of a displayed image is altered for viewers moving relative to the position of the display system screen, thereby imparting a sense of three-dimensional immersion in the scene being displayed. A display generator generates a scene having foreground and background elements, and a display screen displaying the scene. A sensor detects the position of a viewer relative to the display screen, and a processor is operative to shift the relative position of the foreground and background elements in the displayed scene as a function of viewer position, such that the viewer's perspective of the scene changes as the viewer moves relative to the display screen. The foreground and background elements may be presented in the form of multiple superimposed graphics planes, and/or a camera may be used to record the scene through panning at sequential angles. The system may be used to implement virtual windows, virtual mirrors and other effects without requiring viewers or users to modify behavior or wear glasses, beacons, etc.

The present disclosure discloses a display device. The display device includes an interface wherein the interface obtains content to be displayed, and a plurality of display components each having a front display surface to output sub-content. The sub-content is a portion of the content to be displayed. The display device further includes an adjustment assembly. The adjustment assembly moves one or more of the display components in a direction perpendicular to a front display plane.
