Appeal No. 2002-1047
Application 09/083,174
enclosed with a virtual spherical surface R through which light
beams must pass in order to reach point P. Appellants’ invention
records the light beams on the virtual spherical surface R. By
using the mathematics disclosed on pages 12 and 13 of Appellants’
specification, Appellants’ invention is able to reconstruct the
light beams intersected at point P.
Claim 1 is representative of Appellants’ claimed invention
and is reproduced as follows:
1. A method of producing images in a virtual space,
comprising the steps of:
detecting light beams directed toward virtual visual points
from among light beams emitted from or reflected on a surface of
an object, said detection being effected by an image pickup
device in a plurality of positions lying on a virtual closed
surface with which said object is enclosed, wherein said virtual
visual points are not lying on said virtual closed surface;
converting said detected light beams into image pickup
signals;
delivering said image pickup signals to a display device
adapted to display an image toward a visual point of an observer
in a place different from a place where any of said virtual
visual points is disposed; and
displaying said image on a basis of said image pickup
signals in such a manner as if light beams were emitted toward
said visual point of said observer from various points on a
surface of a virtual object disposed in a virtual position
corresponding to the relative positions of said object and any of
said virtual visual points.
