A system for facilitating display misalignment correction includes one or more processors and one or more hardware storage devices storing instructions that are executable by the one or more processors to configure the system to (i) determine one or more user activity attributes associated with user operation of a stereoscopic display system, (ii) based on the one or more user activity attributes, determine one or more correction application attributes, the one or more correction application attributes indicating a manner of applying one or more display misalignment correction operations to align presentation of content in the stereoscopic display system, and (iii) apply the one or more display misalignment correction operations to align the presentation of the content in the stereoscopic display system in accordance with the one or more correction application attributes, thereby effectuating display misalignment correction in a manner that mitigates user discomfort.

A 3D display device includes a display panel, an optical element, a second communication module, and a controller. The display panel is mounted on a moving body and configured to display a parallax image. The optical element is configured to define a propagation direction of image light emitted from the display panel. The second communication module is configured to receive a motion signal indicating a parameter of a motion of the moving body. The controller is configured to cause the display panel to display the parallax image based on the parameter indicated by the motion signal.

Embodiments employ one or more ellipses to determine distance and location in relation to a camera. The captured images of ellipses are analyzed to determine the size of the major axes of the ellipses in the captured image. From the size of the major axis, using mathematics, the distance from the camera can be computed. This distance from the camera combined with the location of the center of the ellipse in the captured image may then be used to locate the ellipse in X-Y-Z space. The ellipses may be placed on articles attached to the body or head of a person, such as a hat or glasses.

An apparatus comprises a receiver (301) for receiving an image representation of a scene. A determiner (305) determines viewer poses for a viewer with respect to a viewer coordinate system. An aligner (307) aligns a scene coordinate system with the viewer coordinate system by aligning a scene reference position with a viewer reference position in the viewer coordinate system. A renderer (303) renders view images for different viewer poses in response to the image representation and the alignment of the scene coordinate system with the viewer coordinate system. An offset processor (309) determines the viewer reference position in response to an alignment viewer pose where the viewer reference position is dependent on an orientation of the alignment viewer pose and has an offset with respect to a viewer eye position for the alignment viewer pose. The offset includes an offset component in a direction opposite to a view direction of the viewer eye position.

A display apparatus according to the present disclosure includes a display unit formed with a lens being arranged for a plurality of adjoining pixels including a left-eye pixel and a right-eye pixel, as a unit, a detection unit attached to the display unit and configured to detect positional information and orientation information of an eye of an observer with respect to a display surface of the display unit, a signal processing unit configured to generate virtual image information for each of the left-eye pixel and the right-eye pixel so as to present a virtual image in an aspect ratio different from the aspect ratio of the display surface of the display unit on the basis of a result of detection obtained by the detection unit, and a display control unit configured to drive the left-eye pixel and the right-eye pixel on the basis of the virtual image information generated by the signal processing unit.

A three-dimensional display system includes a display panel, an optical element and a controller. The display panel includes an active area configured to display a parallax image. The optical element defines a light beam direction of the parallax image. The controller is configured to vary the parallax image based on positions of first and second eyes of the user. The optical element includes a plurality of optical means which are arranged in a parallax direction. The plurality of optical means extend along an inclination direction inclined to a reference direction with respect to a direction perpendicular to the parallax direction. The reference direction is defined, at least in a standard state, based on at least one of a position of the user in the parallax direction in an interior of the moving body and a position relative to the user of a predetermined facility mounted within the moving body.

A method for providing content includes determining a viewing direction of a user viewing a content item comprising a plurality of video streams, selecting two or more video streams of the content item based on the viewing direction of the user and directional data associated with the plurality of video streams, decoding the two or more video streams to form two or more decoded video streams, stitching the two or more decoded video streams to form a combined image, and causing the combined image to be displayed to the user. Systems perform similar steps and non-transitory computer readable storage mediums each store one or more computer programs.
