WHAT IS ICOP?

Icop is an interactive program that can be used to make computer-generated
colors legal in the NTSC (or PAL) color systems.

Often, images generated on the computer are made for use in movies which
ultimately end up on video tape.  However, the range of colors (as specified
by their RGB values) on a computer does not match the range of colors that
can be represented using the NTSC (or PAL) systems.  If an image with
"illegal" colors is sent directly to an NTSC (or PAL) video system for
recording, the "illegal" colors will be clipped.  This may result in an
undesirable looking picture.

This utility will test each pixel in an image to see if it falls within
the legal NTSC (or PAL) range.  If not, the pixel's luminance and
saturation is reduced so that it does fall within legal limits.
