Appeal 2007-1652
Application 09/776,058
change a principle of operation of Kim since, among other things, Anderson
uses digital data to determine hue, but Kim determines hue via the phase
difference between analog signals (Br. 8-9; Reply Br. 6-7).
Appellants also argue that Kim does not teach selecting a first and
second filter as claimed, but rather teaches a single selection of a desired
color (Br. 9; Reply Br. 8). The Examiner argues that Kim’s color selection
key 222 allows the user to select first and second filters simultaneously by
selecting a desired color represented in the color vector scope. According to
the Examiner, each color stored in memory represents the original image
data with the combined filtering effect of (1) a “first filter” with a B-Y color
filtering effect, and (2) a “second filter” with an R-Y color filtering effect
(Answer 15).
We will sustain the Examiner’s rejection of representative claim 15
essentially for the reasons stated by the Examiner. First, we find ample
motivation on this record for the skilled artisan to combine Kim and
Anderson for the reasons previously discussed.7
Second, we agree with the Examiner that each color difference signal
(i.e., B-Y and R-Y) in Kim reasonably constitutes a “filter” giving the term
its broadest reasonable interpretation. These respective color difference
signals essentially dictate the stored colors.
As shown in Figure 3, each stored color is represented in terms of
these color difference signals. That is, each color essentially is the result of
combined effect of both color difference signals. Therefore, selecting a
desired color would, in effect, entail “selecting” both color difference signals
and simultaneously combining their effects to obtain the desired color.
