LUT (Lookup table)
The Fire-i industrial cameras support a LUT (2008 production models or newer), which is providing users with an
image with the user’s defined dynamic range. Through the LUT, users can process the images from saturation to dark.
The LUT can be used optionally with Brightness, Sharpness and Gamma. However, the applied sequence is that the
LUT is applied prior to features like Brightness, Sharpness and Gamma.
(Priority: LUT > Brightness and Sharpness and Gamma)
4.10.1.
4-step knee lookup table
The users can set the 4 points for the images, called the knee, and apply them to LUT.
4.10.2.
User defined lookup table
The users can set defined points (data file) for the images and apply them to the LUT. User’s defined LUT running
procedure is as follows. LUT index is N (o~15). The total index number of user’s defined LUT is 16, but only one user
defined LUT is used at a time.
Priority: User’s defined LUT > 4 point LUT > Features (Brightness, Sharpness, Gamma)
