Grey level transformation is remapping of the grey level values of an input image to new
values which transform the image in some way. The look-up-table (LUT) is used to convert the
greyscale value of each pixel in an image into another grey value. It is typically used to
implement a transfer curve for contrast expansion.
This camera performs a 12-to-8-bit mapping, so that 4096 input grey levels can be mapped to
256 output grey levels (0 to 4096 and 0 to 255).
This camera support 2 LUT, both are identical. The default LUTs is a gain function with value =
1. LUT0 has higher priority as LUT1.
Both LUT can be configured with the built-in Gain / Gamma functions or with a LUT-file
LUTX
Enable LUT X Enable the LUTX
Gain: Linear function. Y = 256 / 4096 * value * X; Valid range for value [1...4].
Gamma: Gamma function. Y = 256 / 4096^value * X ^ value; Valid range for value [0.4...4].
