arrangement could be made with only a lower offset point and no
upper offset point. This would result in darker values in an image to
be preserved, but causing lighter values, excluding absolute white,
would be adjusted.
With the above discussion in mind, we find that one of ordinary skill
in the art would not have found that Farnung teaches the invention, as
recited in claim 5. Farnung discloses a method and system for determining
the contrast and brightness of an adjusted tone reproduction curve.
Particularly, Farnung discloses a lower and upper offset points, indicating
respectively darker and lighter values on the reproduction curve. Farnung
further discloses modifying the reproduction curve by placing additional
pixel component values ranging between the lower and upper offset points
of the curve.
We find that one of ordinary skill in the art, at the time of the present
invention, would have readily recognized that Farnung’s teachings do not
extend to modifying the reproduction curve by placing pixel values outside
of the lower and upper offset points on the curve. Consequently, the
ordinarily skilled artisan would have aptly appreciated, as did the Examiner,
that Farnung does not teach the step of “otherwise modifying the color
