anybody know how to measure "spectral reflectance" from an image displayed on a monitor?

hi folks,

I am wondering what is the "spectral reflectance" and how to measure
it from an image displayed on a CRT monitor or LCD monitor? I guess
this is a term in the computer vision field? or computer graphics
field? I am not sure. Anybody can give some pointers? thank you very
much

Spectral reflectance is usually the frequency dependent amount of
reflected light from a material if the light source is directly above
the surface. I'm not sure how you would measure this with an image on
a CRT or LCD (this wouldn't be reflection then), but maybe there's a
different definition of the process that I am unaware of.

Hope this helps,
