Patent ID: 7414783

Claim:
Apparatus for the optical manipulation of a pair of landscape stereoscopic images, which apparatus comprises an enclosed housing, three ports in the housing with one port forming a photographic interface and the other two ports forming a human interface, said ports allowing light to pass from the human interface to the photographic interface for camera recording, or from the photographic interface to the human interface for each eye of a human without image inversion between the photographic interface and the human interface; said apparatus being characterised by only four reflective surfaces which direct light along three mutually perpendicular directions, each of said surfaces having an edge lying on a flat common plane, said plane also including a division line between adjacent landscape stereoscopic images presented at one said interface, such that light emerges from one said interface in a direction parallel to that of light entering the other said interface, whereby the apparatus causes the landscape stereoscopic images which are side by side with a left eye image left of a right eye image and with the shortest dimension of the landscape images adjacent and which are the human interface to become stacked one image above the other at the photographic interface.
