LUT (Lookup table)
The Fire-i OEM board cameras support a LUT, 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)
