Figure 9-5 Select CSV file
CSV file can be manually modified by users. Currently, .csv storage format saves decimal number of every four
bytes to the first cell of each line in the file, and the maximum value of the number in each cell is 4095, a total
of 4096 lines. The polyline graph of the GUI updates the curve according to the number of the first line of every
16 lines. Failure to follow the format when manually modifying will result in failure to read the file.

Default
The Default option is the LUT data when the device is shipped from the factory, and is the initial value in
each situation. If there is an error in other situation, it will automatically switch to the default. The default
polyline graph is diagonal.
9.1.2.3.
Auto Create LUT
There are five sets of parameters in Auto Create LUT, the maximum LUT range (default value 4095, range
0~4095), minimum value (default value 0, range 0~4032), Gamma (default value 100, range 0~400),
brightness (default value 0, range -150~150), contrast (default value 0, range -150~150), where the
difference between the maximum and minimum values of the LUT range needs to be greater than or equal
to 63.
After selecting the Select Base LUT, when the above parameters are modified, the generated LUT will be
written to the device Flash in real time. At this time, the "Write To Device" is not selected. After the device
is powered off and restarted, the modified parameters will be lost. The generated LUT cannot be restored
by "Read From Device".
If the Select Base LUT is selected as Default or Standard LUT, then adjusting the parameter values in the
LUT group to generate LUT and saving the .lut file will save the parameter values together in the file.
Reading the file again will restore the saved case. If written to the device, the cameras will save and restore
the parameter.
