ICC profiles for pro digital cameras

[Dale]

you have a "linear with light" sensor

you have filtration on the sensor that matches XYZ (tristimulus values)

you add a dial to the camera that allows you to select the lightsource
you are under or are using, the dial, through the electronics, then
populates the appropriate white point tag's data in the ICC profile

this allows you to adjust the XYZ data for appearance in the overall profile

you could even have a little colorimeter attached to the dial to measure
the light source

keep in mind, the sensor does not measure the light color, only photon
counts

requires the right filtration, I believe Kodak owns this intelluctual
property on scanners from Eikonix
