Abstract:
Binocular depth-perception systems use binary, phase-antisymmetric gratings to cast point-source responses onto an array of photosensitive pixels. The gratings and arrays can be manufactured to tight tolerances using well characterized and readily available integrated-circuit fabrication techniques, and can thus be made small, cost-effective, and efficient. The gratings produce point-source responses that are large relative to the pitch of the pixels, and that exhibit wide ranges of spatial frequencies and orientations. Such point-source responses make it easy to distinguish the point-source responses from fixed-pattern noise the results from spatial frequencies of structures that form the array.

Abstract:
A stereoscopic shooting apparatus is described which comprises shooting means (10a, 10b) for taking a stereoscopic shot, which means are adapted to provide a pair of stereoscopic images comprising a right image and a left image, wherein said shooting apparatus comprises: a computation block (12) receiving at its input said pair of stereoscopic images from said shooting means (10a, 10b); a normalization and quantization block (14) subjecting the values of said parameter computed in said computation block (12) to normalization, and preferably also to quantization; association means (16) adapted to associate graphic information with said parameter; an overlay block (18) overlaying said graphic information on said pair of stereoscopic images and outputting said overlaid images to visualization means (22); visualization means (22) for displaying said graphic information through an image overlaid on at least one image of said pair of stereoscopic images, thus forming a composite image.
Abstract:
L'invention concerne un procédé de transmission de deux couples consécutifs d'images comprenant les étapes suivantes: décimer chaque image (L, R) avec un rapport 2; assembler les deux images décimées (L1, R0) de chaque couple en une image composite (10'); transmettre les images composites; et reconstruire des images complètes (16) à partir des images composites. Dans la décimation, on conserve, du point de vue spatial, dans les images du deuxième couple, les informations supprimées des images du premier couple; et on reconstruit les images complètes par un traitement de désentrelacement (18) à partir des images composites.

Abstract:
Preparing a three dimensional (3D) video graphical overlay based on a two dimensional (2D) graphical image in a decoded stereoscopic video signal. This includes receiving the 2D graphical image and receiving 3D information associated with the 3D video graphical overlay. This also includes reproducing, using a processor, the 2D graphical image to form a first view graphical image and a second view graphical image in a graphics window. This also includes mapping the first and second view graphical images, using the 3D information, to frames in the 3D video to form a 3D video graphical overlay of a 3D video stream. This also includes blending the 3D video graphical overlay and the 3D video stream.
