off by the polarizing filters in Faris’ Figure 5c.
In summary, we find that the light source 12 in Faris
illuminates an area of space determined by the intensity of
the light source and the associated optical elements which
determine whether light from the light source gets through.
We agree with the examiner that there are regions of space
above layer 19 that are illuminated by light source 12 as long
as the light is not cut off by polarizing filters 21. Since
the polarizing filters of the autostereoscopic mode are placed
differently from the polarizing filters of the stereoscopic
mode, these regions of space are different from each other.
Thus, we agree with the examiner that the illumination system
of Faris illuminates two different regions of space in which
the three dimensional image is viewable. Accordingly, we
sustain the anticipation rejection of claims 1-4, 10, 11, 19
and 20.
Claim 22 is argued separately by appellants. With
respect to claim 22, appellants argue that Faris does not
disclose a viewing aid in cooperation with the display in the
autostereoscopic mode [brief, pages 8-9]. The examiner
responds that he is reading the viewing aid on the control
