Changing the Values in the Luminance Lookup Table and Enabling the Table
Using Basler pylon
You can change the values in the luminance lookup table (LUT) and enable the use of the lookup
table by doing the following:
1. Use the LUTSelector parameter to select a lookup table. (Currently there is only one lookup
table available, i.e., the "luminance" lookup table described above.)
2. Use the LUTIndex parameter to select an index number.
3. Use the LUTValue parameter to enter the substitute value that will be stored at the index
number that you selected in step 2.
4. Repeat steps 2 and 3 to enter other substitute values into the table as desired.
5. Use the LUTEnable parameter to enable the table.
You can set the LUTSelector, the LUTIndex, and the LUTValue parameters from within your
application software by using the pylon API. The following code snippet illustrates using the API to
set the parameter values:
// Select the lookup table
camera.LUTSelector.SetValue(LUTSelector_Luminance);
// Write a lookup table to the device.
// The following lookup table causes an inversion of the sensor values
// (bright -> dark, dark -> bright)
for (int i = 0; i < 4096; i += 8)
{
camera.LUTIndex.SetValue(i);
camera.LUTValue.SetValue(4095 - i);
}
// Enable the lookup table
camera.LUTEnable.SetValue(true);
For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide
and API Reference.
You can also use the Basler pylon Viewer application to easily set the parameters.
Changing the Values in the Luminance Lookup Table and Enabling the Table
Using Direct Register Access
When setting up the luminance lookup table via direct register access, two registers are involved:
the LUT register and the LUT Enable register.
 The LUT register is simply an array register that holds the 4096 12 bit values described earlier
in this section. As a first step to using the lookup table feature. You must populate this register
with 12 bit values.
 Once the LUT register has been populated, you can enable the use of the lookup table by
setting the value of the LUT Enable register to 1 (enabled).
For more information about direct register access, see Section 3.2 on page 28.
