Abstract
The invention relates to a method of reproducing a gray scale image () in colors on a color monitor (), in which method each shade of gray () is assigned, using a look-up table (), a given output value (R, G, B) for driving the electron guns (R,G,B) 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 () is preserved; this is important notably for the interpretation of medical images. Additionally, the special display properties of the monitor () and/or the ambient circumstances can be taken into account in the look-up table () in order to optimize the reproduction of the gray scale image.
