Table 10: Maximum Gain Off Example; Table 11: Maximum Gain Setting Examples - Teledyne FLIR A68 Series User Manual

For example, using the following sample image, the dynamic adaptive contrast mode
stretches the image automatically (max gain feature = off) such that the resulting 8-bit
image uses most of the dynamic range available (~215 DN) without saturating. This
results from the fact that the dynamic adaptive contrast has calculated a gain of ~1.5
to apply to the image.

Table 10: Maximum Gain Off Example

Image
Max Gain = Off
If however, the maximum gain was set to 1, the 16-bit image would not be stretched
and the max-min range remains the same in the 8-bit image.

Table 11: Maximum Gain Setting Examples

Image
Max Gain = 1
A maximum gain of less than 1 reduces the max-min range in the 16-bit image when
mapping to 8-bits. For example, a maximum gain of 0.5 effectively reduces the 8-bit
range in half from that present in the 16-bit image.
