additionally asserts (answer, pages 7 and 8, see also pages 11
and 12) that “[i]t is also desirable to transform different types
of images differently to optimize fidelity. It would have been
obvious . . . to use Oshikoshi’s step of identifying an image
type in Spaulding’s method of transforming input colors to output
colors to optimize image quality, because each part of the images
can be corrected with the most suitable process as pointed out by
Oshikoshi in column 2, line[s] 21-24.” With respect to claims
10, 19, and 21 the examiner's position (answer, pages 10-12) is
that Spaulding does not explicitly show the step of modifying
colors for different objects in a predetermined category. The
examiner asserts (id., page 7, see also page 11) that "[i]t would
have been obvious to . . . apply Oshikoshi's method of
determining a limit parameter to set the limit value for each
region transformed with Spaulding's method, because different
part[s] of an image can be corrected with the most suitable limit
value to optimize the smoothness of saturation transition and
therefore provide a good image quality."
Appellants assert (brief, page 12) that Oshikoshi is
directed to color correction that takes place within the context
of a single color space, and that the color correction process of
Oshikoshi, i.e., the shifting of color values to achieve color
