The invention relates to a method of reproducing a gray scale image (1)
in colors on a color monitor (6), in which method each shade of gray (2)
is assigned, using a look-up table (4, 5), a given output value (R, G, B)
for driving the electron guns (8R, 8G, 8B) of the color monitor.
Assignment is performed in such a manner that a given color deviation is imparted
to successive shades of gray, which deviation enables differentiation of the shades
of gray by a human observer without such deviations becoming disturbing. Consequently,
the information concerning the optical density of the original gray scale image
(1) is preserved; this is important notably for the interpretation of medical
images. Additionally, the special display properties of the monitor (6)
and/or the ambient circumstances can be taken into account in the look-up table
(4, 5) in order to optimize the reproduction of the gray scale image.
