virtual closed surface and where the virtual visual points are
not lying on the virtual closed surface. See pages 7 through 12
of Appellants’ brief and Appellants’ reply brief.
Matsugu is concerned with an image recording/reproducing
method which can generate and display a stereoscopic image. See
Matsugu, column 1, lines 10 through 15. Matsugu’s figure 4 shows
the principle of parallax information conversion. Referring to
figure 4, SL and SR respectively represent the camera sensor
surfaces upon phototaking. SL0 and SR0 respectively represent the
retinas of naked eyes or display surfaces upon reproducing, and P
represents the point on a certain object in real space. OL0 and
OR0 respectively represent the lens centers of the left and right
phototaking systems representing the eyes of the observer. See
Matsugu, column 4, lines 10 through 25. Thus, Matsugu teaches a
system wherein the virtual visual points, which correspond to the
eyes of the observer, are lying on the virtual closed surface on
which the cameras are positioned. Therefore, Matsugu cannot
anticipate Appellants’ claimed invention which requires that the
“virtual visual points are not lying on said virtual closed
surface” as recited in Appellants’ claim 1. Furthermore, Matsugu
fails to teach detecting light beams directed toward virtual
visual points wherein detection is being effected by an image
