Hi,
I'm doing some color induction experiments, and need to allow the user
to adjust the color of a test-patch to match the induced color on the
CRT. I would like to do this in the CIE colorspace.
The toolbox includes RenderDemo.m, which shows how to find the RGB
value for a given xyY, but requires a calibration file. I'd like to
generate such a calibration file, but it appears that all of the
routines require a PR650, or some equivalent device which measures
SPD, whereas I have a CRS ColorCal, which only measures xyY. Is there
a way to modify this code so that a color meter can be used instead?
Or is there some other approach (other than trial-and-error) to
converting from CIE to RGB? I've found various matrices posted on the
web which convert between the two spaces, but none make very accurate
conversions, since they are not calibrated to the monitor we are using.
Thanks!
