A near-eye display device comprises a left-eye optical system and a right-eye optical system. Each of the left-eye optical system and the right-eye optical system comprises a holographic optical component positioned in a field of view of a user eye, an image source configured to emit imaging light, and an alignment optical component, wherein projection beam path between the image source and the light-deflecting optical component and an alignment beam path between the alignment optical component and the light-deflecting component share a common optical path.

Disclosed herein are a method and apparatus for normalizing the size of content in a multi-projection theater and a computer-readable recording medium. The method may include receiving theater parameters stored in a database, computing the scale factor of an image project on a main screen based on the received theater parameters, controlling the image projected on the main screen by incorporating the computed scale factor into the image, and controlling an image projected on a sub-screen so that the height or width of at least any one of images of sub-screens having a different pixel size or ratio from the controlled image of the main screen is identical with a height or width of the controlled image of the main screen.

The present disclosure provides a 3D image display method for displaying 3D image on a handheld terminal display screen. The method includes the following steps. The handheld terminal detects a current screen display mode to determine whether the handheld terminal triggers a horizontal-vertical screen display mode change. The handheld terminal determines the current screen display mode as a horizontal mode or a vertical mode when the handheld terminal triggers a horizontal-vertical screen display mode change. The handheld terminal determines 3D image arrangement parameters based on the current screen display mode. The handheld terminal rearranges the 3D image to be displayed to obtain a revised 3D image based on the adjusted 3D image arrangement parameters. The handheld terminal displays the revised 3D image in the current screen display mode of the handheld terminal.

Presenting an image preview includes receiving image data from a GPU buffer, wherein the GPU buffer is associated with a media manipulation application, obtaining an orientation data for a display device, rendering a preview image using the image data and the orientation data, and displaying the preview image using the display device, wherein the preview image is displayed while the image data is utilized by the media manipulation application, and wherein the preview image is dynamically modified when the image data is modified by the media manipulation application.

A head-mounted display device includes a deriving section that derives an object distance of a real object included in an outside scene to be imaged and a relative pose of the real object with respect to an imaging section, a parameter selection section that selects one parameter group among a plurality of parameter groups for displaying an AR image associated with the real object on an image display section in accordance with the object distance; and a display image setting section that sets a display image in which a pose of the AR image and a pose of the real object are associated with each other, on the basis of the object distance, the relative pose of the real object, and the selected one parameter group, and displays the display image on the image display section.

A camera calibration system jointly calibrates multiple cameras in a camera rig system. The camera calibration system obtains configuration information about the multiple cameras in the camera rig system, such as position and orientation for each camera relative to other cameras. The camera calibration system estimates calibration parameters (e.g., rotation and translation) for the multiple cameras based on the obtained configuration information. The camera calibration system receives 2D images of a test object captured by the multiple cameras and obtains known information about the test object such as location, size, texture and detailed information of visually distinguishable points of the test object. The camera calibration system then generates a 3D model of the test object based on the received 2D images and the estimated calibration parameters. The generated 3D model is evaluated in comparison with the actual test object to determine a calibration error. The calibration parameters for the cameras are updated to reduce the calibration error for the multiple cameras.

A method of displaying a stereoscopic image includes outputting a left-eye image to a first and a second display block of a display panel during an N-th frame. Light is provided to the first display block during a first period of the N-th frame and light is provided to the second display block during a second period of the N-th frame. A right-eye image is output to the first and second display blocks of the display panel during an M-th frame. Light is provided to the first display block during a first period of the M-th frame and light is provided light to the second display block during a second period of the M-th frame.

A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium having computer instructions to retrieve from a first high definition (HD) channel utilized for transporting two-dimensional media programs a first HD stereoscopic data stream, retrieve from a second HD channel utilized for transporting two-dimensional media programs a second HD stereoscopic data stream, and present a 3D HD imaging stream comprising the first and second stereoscopic data streams. Other embodiments are disclosed and contemplated.

A display apparatus switching between a two-dimensional (2D) display mode and a three-dimensional (3D) display mode is provided. The display apparatus includes: an imaging device configured to capture an image a pair of 3D glasses worn by a user to view an image displayed in the 3D display mode, wherein the 3D glasses are switchable between a plurality of different states; a transmitter/emitter module configured to remotely control the 3D glasses so as to switch the states of the 3D glasses; and a controller configured to determine whether the user is wearing the 3D glasses based on a state of the 3D glasses in the image captured by the imaging device, and to control the display apparatus to operate in the 3D display mode when it is determined that the user is wearing the 3D glasses.

Systems and methods for processing a pair of 2-D images are described. In one example, a stereoscopic set of images is converted into a collection of regions that represent individual 3-D objects in the pair of images. In one embodiment, the system recovers the 3-D point P for each point p that appears in both images. It estimates the 3-D orientation of the floor plane, and the image capture planes and their height from the floor. The system then identifies the collection B of points P that do not represent points on the floor and generates a projection C of B onto a plane parallel to the floor. It blurs the projection C and identifies peaks in the blurred image, then fits symmetric figures to the points in C around the identified peaks. The system projects the 3-D figures associated with the symmetric figures back onto the 2-D images.
