5.1.2.3 DDE
Digital Detail Enhancement (DDE) is an algorithm which can be used to enhance image details
and/or suppress fixed pattern noise. DDE parameters are computed automatically based on scene
content and range from -20 to 100. Higher values represent higher degrees of detail enhancement.
If no enhancement is desired, a value of 0 should be set. Values greater than 0 sharpen the image,
while values less than 0 soften the image and filter fixed pattern noise. Although large values of
DDE will significantly enhance the edges of objects in the scene, it can also raise the fixed pattern
noise in the image.
5.1.2.4 ACE
The Active Contrast Enhancement (ACE) feature provides a contrast adjustment dependent on the
relative scene temperature. ACE thresholds greater than 0 impart more contrast to hotter scene
content and decrease contrast for colder scene content (e.g. sky or ocean). ACE threshold settings
less than 0 do the opposite by decreasing contrast for hotter scene content and leaving more of the
gray-scale shades to represent the colder scene content. ACE can range from -8 to 8 where -8
decreases contrast in darker regions while +8 increases contrast in darker regions. Although
individual operator preferences may vary, FLIR recommends using positive values of ACE when
selecting WhiteHot-based color palettes and negative values when selecting BlackHot. Color-based
palettes typically require only small (if any) changes to ACE.
5.1.2.5 SSO
The Smart Scene Optimization (SSO) value defines the percentage of colors that will be linearly
mapped. With SSO enabled, the difference in gray shades between two objects is more
representative of the difference in temperature. SSO helps to set how linear the Scene algorithms
are to provide the highest amount of perceived contrast in every scene. SSO can range from 0 to
100%.

5.1.2.6 Save Custom Scene Presets

Two user configurable Scene presets are provided. Saved settings include Scene algorithm, ROI,
DDE, ACE, and SSO. The Save buttons store the presets, while the Custom selections (on the Scene
page) recall them. To use this feature, begin by selecting the desired Scene preset. Once selected,
the Scene preset can be further optimized using the manual control sliders. Record the desired
settings by hitting the Save button.
5.1.3 IR Palette
The Duo Pro R detects and images long wave infrared radiation. Within the camera, this radiation
is mapped (as determined by the Scene Preset selected) to a range of 255 colors. In a black and
white palette, this range is converted to shades of gray with 0 being totally black and 255 being
totally white. Different palettes are available to change the appearance of the image. The most
common selection is either White Hot (hotter objects appear brighter than cooler objects) or Black
Hot (hotter objects appear darker than cooler objects).
