VIDEO HOLOGRAM AND DEVICE FOR RECONSTRUCTING VIDEO HOLOGRAMS USING GEOMETRICAL CALCULATION
First Claim
1. A method of generating a video hologram, comprising the steps of:
- (a) selecting a point in the three dimensional scene to be reconstructed;
(b) defining an observer window through which the reconstructed three dimensional scene will be seen;
(c) tracing a pyramid from the edges of the observer window through the point and onto a region that forms only a portion of a hologram bearing medium;
(d) generating, solely in that region of the hologram-bearing medium, holographic information needed to generate a holographic reconstruction of the point.

Abstract
A geometrical method for working out how to encode a hologram onto a hologram bearing medium is disclosed. The method involves (a) selecting a point on the three dimensional scene to be reconstructed; then (b) defining a virtual observer window through which the reconstructed three dimensional scene will be seen; then (c) tracing a pyramid from the edges of the observer window through the point and onto a region that forms only a portion of a hologram bearing medium; and finally (d) generating, solely in that region of the hologram-bearing medium, holographic information needed to generate a holographic reconstruction of the point.
