Due: In class, 5p.m. Tuesday April 14


Color inkjet printers use the CMY model.  To make direct printing easier,
it is possible to purchase CMY cameras.  

a) Explain why color printers use CMY while CTR displays use RGB.
   Which strategy does a LCD display use?

b) Draw spectral curves depicting the spectral sensitivity of a CMY camera,
   based on Figure 4.17(a) of the text.

c) Plot that sensitivity on three dimensions, as in Figure 4.20(a).

d) Determine a transformation to convert CMY to RGB.

e) Discuss whether the colors resulting from CMY to RGB conversion are as good
   as the colors of a direct RGB camera or of the human eye, as in Figure 4.10.

f) Compare the colors achieved by converting a CMY camera to RGB and then back
   to CMY, with the colors achieved by converting a RGB camera to CMY for printing.
