Look-up table (LUT) (D, G)
The temperature data of the microbolometer sensor is generally non-linear.
The LUT linearizes the data that have already been pre-corrected by two-point,
background and bad pixel correction, resulting in more exact temperature val-
ues. The LUT is implemented as 12-bit LUT.
The operation mode of the LUT is controlled with parameter G.
The following value assignment is applied:
Example
Activate the LUT for linearization.
> G=1[CR]
The file containing the LUT data is set with parameter D. Ex factory the LUT is
determined one time and stored into the flash. As generally only one LUT exists
in the camera, it is not necessary to change this parameter.
Example
Initialisation of the LUT with data from file number 0x80.
> D=80[CR]
Note

This function is currently not available as GigE Vision feature.
Value Description
0 Deactivated. Data are passed
through transparently.
1 Activated
2 Deactivated
Test mode: LUT data are output
sequentially. (*)

(*) Operation mode 2 exists only for test purposes. If activat-
ing this mode, the module does not transmit any incoming
image data anymore. It becomes a data source itself instead.
