Default contrast Default brightness
Increasing the contrast uses more of the outer colors of the
color palette i.e. black and white in the rainbow example.
Increasing the thermal brightness uses more of the upper
half of the color bar.
Reducing the contrast uses less of the outer colors of the
color palette, and uses more of the central colors i.e. green
and yellow in the rainbow example.
Decreasing the thermal brightness uses more of the lower
half. See the examples in Figure 18 for more information.
Figure 19: These 6 figures show the effect of increasing and decreasing the auto mode’s brightness and contrast.
The practical advantage of this is that the user can completely control the appearance of the image without having to adjust
the level and span manually when viewing different scene temperatures.
NOTE : The brightness and contrast can be reset back to the defaults by pressing hot button 4 to manual mode,
and then hot button 4 again back to auto mode.
