Appeal No. 96-1628
Application No. 08/167,617
programmable filter 52, respectively, of previous embodiments.
(See Specification, page 13, lines 9-12 and 21-32, and page
14,
lines 2-9.) Additionally, appellant states (Specification,
page 14, lines 30-35) that
the programmable filter could be incorporated as an
integral part of an integrated image sensor with the
array of optical filter elements of the programmable
filter overlying the array of sense elements of the
image sensor. The array of filter elements (e.g.
LCD elements) could be formed as a set of further
layers of integration over those for the sense
elements.
Accordingly, the specification clearly provides a
corresponding structure for the "means . . . for selectively
causing a reduction in the voltage levels of said video image
signals corresponding to said respective areas." Further, the
corresponding structure attenuates only those intensities
exceeding the threshold. Therefore, we find that the claim is
limited to a means that reduces the voltage level of video
images that correspond to intensities above the threshold.
Asao does not limit the attenuation to brightnesses above the
threshold.
