Look-up table (LUT) and gamma function
The Guppy PRO camera provides
one
user-defined look-up table (LUT). The use
of this LUT allows any function (in the form Output = F(Input)) to be stored in
the camera's RAM and to be applied on the individual pixels of an image at
runtime.
The address lines of the RAM are connected to the incoming digital data, these
in turn point to the values of functions which are calculated offline, e.g. with a
spreadsheet program.
This function needs to be loaded into the camera's RAM before use.
One example of using an LUT is the gamma LUT:
There is one gamma LUT (gamma=
0.45)
Output = (Input)
0.45
or with normalized values:
Output/1023 = (Input/4095)
0.45

Note
The use of the mirror function with color models and image
output in RAW format has implications on the Bayer-ordering
of the colors.
