Appeal No. 95-4722
Application 07/946,226
that the perspective axis of the view be changed. This result
is not accomplished by the simple interpolation of captured
values according to appellants [brief, pages 12-14].
Based on the record established in this case, we agree
with appellants that the teachings of Wah Lo and Travis do not
collectively suggest the invention of claims 1-17 and 21-24.
Wah Lo has nothing to do with changing apparent viewing
positions in creating a depth image. Rather, Wah Lo teaches
that a depth image on a lenticular photograph should have
precisely three image bands under a lenticular screen of
approximately thirty degrees [column 4, lines 34-37]. The
three image bands result from a picture taken of a scene
through three different lenses. The apparent viewing position
of each view is established by the fixed relationship between
the lenses. Wah Lo does nothing in creating the photograph to
change these apparent viewing positions [note that the
apparent viewing positions remain unchanged in going from FIG.
6 to FIG. 7]. Whatever the apparent viewing position is in
Wah Lo when the image is captured is retained in producing the
lenticular photograph.
