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. 

5. 

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.
