Fig. 26 Colour key 256 colours(left)and 16 colours (right)
The "16 Steps" menu item toggles between the standard colour depth of 256 colours and a lower colour
depth of 16 colours It is usually possible to distinguish between up to 256 different temperature values
with colours. By activating the "16 Steps" function, only 16 temperature values can be distinguished. This
gradation is also particularly visible on the colour key (see Fig. 26).
Fig. 27 linear greyscale colour key (left) and its logarithmic representation (centre), and 16 colour
logarithmic representation (right)
The representation of the temperature values can be toggled between a linear and a logarithmic
progression with the
"Logarithmic" menu item The default representation of the temperatures is a linear
progression. By activating this function, it is possible to use a greater colour resolution for the lower
temperature range than for the higher. The effects of the logarithmic representation can be seen in Fig.
27. The linear colour key is shown on the left. In the centre, the colour key with logarithmic representation
set is shown. For better clarity of the logarithmic separation, a representation with only 16 colours is
shown on the right. Here, the higher colour resolution for the lower temperatures is also clear.
