An apparatus for generating a first, second and third pseudocolor video signals from monochromatic video signals having a range of possible amplitudes I between 0 and A, said range comprising n sections, n being a positive integer, and A being a predetermined constant, said apparatus comprising:

• means for generating a first, second and third pseudocolor video signals S1, S2, S3 whose amplitudes are constants or functions of I in each of said n sections, wherein at least the amplitudes of the pseudocolor video signals in one section are not constants and are functions of I that are different from the constant or function in at least one other section, said functions being substantially linear or sinusoidal;
• and
• means for outputting said three pseudocolor video signal.
