The spectral formula is given by:


And the equations for X,Y,Z are:
      

The raw xyz data provided The linearly interpolated xyz data


CIE XYZ->RGB Conversion Matrix Per-Channel Scaling Max-Channel Scaling Clamp Negatives, Per-Channel Scaling Clamp Negatives, Max-Channel Scaling Clamp All [0..255] Clamp All [0..1] Tim's Special #1 Tim's Special #2


These images were obtained using the conversion matrix found in Glassner's Principles of Digital Image Synthesis.


These images were obtained using the above conversion matrix found here.
 
The rest of these images were obtained using the various conversion matricies found here.


This matrix is supposed to be conversion to PAL and SECAM.


This matrix is supposed to be conversion to NTSC.


This matrix is supposed to be conversion to SMPTE-C.


This matrix is supposed to be conversion to an interim HTDV standard.


This matrix is supposed to be conversion to an alternate NTSC coding.



*All images were generated by a VB program running on a PC in 16M color mode.
