Ishikawa teaches such modification of mid-range value by interpolation. We
agree.
We find that the cited references are cumulative to Farnung. Kishida,
for example, teaches taking a weighted average of respective reference tone
values to obtain a modified reproduction curve. In addition, Hieda discloses
a gamma correction circuit that uses a reference signal to correct an output
signal. The ordinarily skilled artisan would have readily recognized that
these teachings, taken alone or in various combinations, do not amount to
interpolating image data to blend transitions between light and dark areas of
the image. Ishikawa, unfortunately, does not remedy such deficiencies.
After considering the entire record before us, we conclude that the
evidence relied upon and the level of skill in the particular art would not
have suggested to the ordinarily skilled artisan the invention as set forth in
claims 10 through 16. Accordingly, we reverse the Examiner’s rejection of
claims 10 through 16.
III. Under 35 U.S.C. § 103, is the Rejection of Claims 1 through 4, 17
and 18 as being unpatentable over Various Combination of Sugimoto,
Wu and Hieda Proper?
Appellant argues that the various combinations of Sugimoto, Wu and
Hieda do not render claims 1 through 4, 17 and 18 obvious. Particularly, the
