2-6-2 Contrast Conversion
The LUT intensity can be mapped (re-assigned) while observing a histogram.
Mapping (re-assignment) results in changing the image contrast.
An image acquired by observation contains intensity information in values from 0 to 4095,
but the intensity information used in actual display takes values from 0 to 255 by assigning
the original values from 0 to 4095 to values from 0 to 255 usually. This facility changes the
contrast by noticing a certain section between 0 and
4095 and mapping this section to values between 0
and 255.
