the various viewing environments and for the adaptive effects
that each environment would have on the color perceptions of a
viewer.
Representative claim 41 is reproduced as follows:
41. A method for forming at least one transform for
transforming colorimetrically-specified values to intermediary
color-image data encoding values, comprising the steps of:
a) specifying an input-image viewing environment in terms
of its illuminant spectral energy distribution, amount of
viewing flare light, surround type, and adaptive white point
chromaticities;
b) specifying an encoded-image viewing environment in
terms of its amount of viewing flare light, surround type, and
adaptive white point chromaticitiers;
c) generating colorimetrically-specified test color
values which adequately sample and cover the useful
colorimetric value range;
d) adjusting said colorimetric values in accordance with
the difference in the amount of viewing flare light specified
for the input-image viewing environment and the encoded-image
viewing environment to form flare-adjusted colorimetric
values;
e) adjusting said flare-adjusted colorimetric values in
accordance with the difference in the surround types specified
for the input-image viewing environment and the encoded-image
viewing environment to form surround-adjusted colorimetric
