Help!

I am using an AT&T Targa 16 board to capture images from a video camera.
It stores each pixel in RGB with 5 bits/color.  I would like to display
the image on a VGA display, except that it only has a color pallet of
256 colors.  How should one map from the larger color pallet to the
smaller one?  I naively thought this would be trivial, but am not satisfied
with my results.

Also, as a side question, how to you map from RGB to HLS?

All comments, pointers, hints, clues and remarks are gratefully accepted.
Thanks in advance,
