12.1.7 Color Distribution
There are two Color Distribution modes; Linear and Histogram.
In Linear mode, the colors are distributed linearly from the darkest
to the brightest pixel in the image.
In Histogram mode, the colors are distributed based on the contents
of the image.
The Histogram mode normally gives the best image, but for small details
the Linear mode may be better. The Linear mode also gives a more intui-
tive perception of the temperature contents.
NOTE: The most suitable color distribution setting depends on many factors. Toggle be-
tween Histogram and Linear to see which mode suits the current situation best.
