represent isochrome and close number; T (λ) represents light source transmitance;
represent normalization fixed number.
The pass of chromaticity coordinates x, y and transmitance Y and tristimulus values is:
X=X/ (X+Y+Z) formula (2)
Y=Y/ (X+Y+Z) formula (3)
Y=Y formula (4)
The pass of white point transmitance and RGB transmitance is:
T
w(λ)=[T
r(λ)+T
g(λ)+T
