another device-dependent color space. (col. 1, lines 20-24).
Input color values in an input color space are transformed to
output color values in an output color space (col. 3, lines 12-
14). Spaulding provides 18 adjustable parameters which can be
used to individually adjust the hue, saturation, and lightness of
the 6 primary colors (R, G, B, C, Y, M)(col. 4, lines 18-20).
Color reproduction characteristics can be adjusted in a custom
manner while maintaining the desired tonal reproduction on the
neutral axis (col. 4, lines 15-17). To preserve continuity of
colors in the color space, lower saturation colors are adjusted
to maintain smooth color gradations (col. 9, lines 29-32).
From our review of Spaulding, we agree with appellants
(brief, page 7) that Spaulding does not meet the recited step of
detecting whether a nominal color for one or more objects in an
image is comprised of plural components. The examiner (answer,
page 4) relies upon col. 6, lines 28-60 of Spaulding for a
teaching of this limitation. We find that the portion of
Spaulding relied upon by the examiner refers to figures 7 and 8.
Figure 7 discloses transformation of color values from an input
device such as a CRT which uses R, G, B components, to an output
device such as a thermal printer which uses C, Y, M components.
In the color transformation shown in figure 8, each of the
