Internal Calculation Processing
The instrument calculate data according to following formula
Chromaticity coordinate
xy chromaticity coordinates of a XYZ color coordinate system
u'v' chromaticity coordinates of a UCS color coordinate system
Color Temperature, Deviation
Color temperature and deviation are calculated according to JIS Z 8725 "Method for
determining distribution temperature and color temperature or correlated color temperature
of light source."
