collection of the most saturated color values.
Subset 16 is a collection of relatively unsaturated
color values of the type commonly found in
photographic scenes. A color enhancement strategy
is assigned to subset 12 which performs a mapping
of input colors to saturated colors in the output
color space. A strategy for mapping input colors
to output colors colorimetrically is applied to
subset 16. The remaining colors forming subset
14 are mapped in a manner preserving continuity
between the subsets 12 and 16.
From these teachings of Spaulding, we find that the claimed limit
value is met by the boundary between subsets 16 and 14, and that
the claimed threshold value is met bythe boundary between subset
14 and subset 12. We additionally find that adjusted color
values are obtained for the remaining colors found in subset 14,
in a manner preserving the continuity between subsets 12 and 16,
and that Spaulding discloses producing adjusted color values for
nominal colors that have parameter values that lie in a range
from the limit value to the threshold value. We further find
that the color values beyond the threshold value, in subset 12,
having the most saturated colors, are reduced using uniform
compression. Moreover, we find that the color values of subset
16, which have a parameter value below the limit value are
maintained. However, claim 9 requires more. Claim 9
additionally requires that color values beyond the threshold
value are reduced "to values that lie within a range from said
