<p><font size="4">Dear CVNet,</font></p>
<p><font size="4">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...<br>
</font></p>
<p><font size="4">Anyone have tips on how to calibrate a 4-color
wheel DLP device?</font></p>
<p><font size="4">Thanks, <br>
