We are trying to get decent color calibration (i.e. a table/function
from [r,g,b] to cie, cones, or some other standard color space) on an
old dlp projector (NEC NP4100) with a 4-color wheel. The problem is
challenging because the projector appears to add white in varying
amounts to colors in an internally determined way (and we cant find a
setting to turn that off). We found an old reference or two on the
problem, but thought CVNet might have updated knowledge. So...
Anyone have tips on how to calibrate a 4-color wheel DLP device?
