Receiver-side adjustment of stereoscopic images


There is provided a video apparatus having a stereoscopic display associated therewith, the video apparatus arranged to: receive at least one image and at least one reference parameter associated with said image; calculate a baseline distance for synthesizing a view, the calculation based upon the received at least one reference parameter and at least one parameter of the stereoscopic display; synthesize at least one view using the baseline distance and the received at least one image; and send the received at least one image and the synthesized at least one image to the stereoscopic display for display.. .

Method and stereoscopic imaging


A device is disclosed that utilizes color or polarization to generate two separate images of the same object taken from the two perspectives that correspond to the left and right eyes of an observer. The two separate images are captured through a single camera objective (e.g., a single shutter camera), resulting in a single image with 3d information encoded in the color or polarization.

Systems and methods for multiview metrology


Described are systems and methods for measuring objects using stereoscopic imaging. After determining keypoints within a set of stereoscopic images, a user may select a desired object within an imaged scene to be measured.

Head mounted image-sensing display device and composite image generating apparatus


The invention provides a head mounted image-sensing display device including a pair of image-sensing units (18r, 18l) that stereoscopically capture a physical space and output a pair of stereoscopic images, and display units (13r, 13l) for displaying images for the right eye and images for the left eye. Image sensing parameters that are previously measured for the image-sensing units are stored in image sensing parameter storage units (26r, 26l).

Anaglyph ghost cancellation


Ghosting of images can be produced by the use anaglyph techniques to produce stereoscopic images. Ghost effects can be produced when filtering is applied to images by displays such as televisions or monitors.
