TWB mode: TWB is named Thermal White Balance. It balances color distribution
on the entire temperature span of the image.

When the TWB function is turned on, the overall image color display will be
balanced non-linearly according to the histogram of overall temperature.

It makes the extreme hot/cold area’s color display weaken, while other areas are
enhanced with more gradients.
