Method for mirroring 3D objects to light field displays

Systems and methods are described for mirroring 3D content from a first display (which may be a handheld 2D display) to a second display (which may be a 3D display, such as a light field display). The 3D content is initially displayed (e.g. as a 2D projection) on a the first display. The relative positions and/or orientations of the first and second displays are determined. The position of a user viewing the content may also be determined or may be inferred from the position and orientation of the first display. The second display is provided with information used to display the 3D content with a size and/or orientation that preserves the original apparent size and/or apparent orientation of that content from the perspective of the user.

Information processing apparatus and information processing method for suppressing crosstalk while suppressing degradation in image quality

An information processing apparatus (30) includes: an estimation unit (33B) that estimates the crosstalk amount based on a relative positional relationship between a viewing position of a viewer of a display device (10) and a pixel a screen of the display device (10); and a generation unit (33C) that generates an image to be displayed on the display device (10) by correcting a value of each of a plurality of pixels of the screen based on the crosstalk amount.

3D DISPLAY DEVICE, HEAD-UP DISPLAY, MOVING BODY, AND PROGRAM
20210356740 · 2021-11-18 · ·

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.

A stereoscopic video playback device is provided that processes original stereoscopic image pairs taken using parallel-axis cameras and provided for viewing under original viewing conditions by scaling and cropping to provide new viewing condition stereoscopic video on a single screen.

HEAD-MOUNTED DEVICE FOR DISPLAYING PROJECTED IMAGES
20210344895 · 2021-11-04 ·

A system includes a projection device configured to project images onto a receiver surface of a viewing device. The viewing device includes a screen having the receiver surface and a viewing surface opposite the receiver surface. The screen is configured to permit transmission of the images through the screen, from the receiver surface, to the viewing surface such that the images are viewable on the viewing surface. The viewing device also includes a focusing lens configured to focus the images for a user when wearing the viewing device. Further, the system includes a tracking system configured to determine a location and orientation of the receiver surface of the viewing device. The projection device is configured to adjust image properties of the images based at least in part on the determined location and orientation of the receiver surface.

Multi-view display control

A multi-view display controller (100, 200, 300) generates view information specifying view directions along which media data a media content is to be projected on a multi-view display (2) and specifying a selected view direction along which additional information is to be simultaneously projected as media data of the media content. The multi-view display controller (100, 200, 300) thereby enables an intuitive and efficient communication of additional information to the viewer (5) on the multi-view display (2).
