I was puzzled at the lsc gain table when I use lsc module source code. Since the r/Gr/Gb/bGain table is [13*17], I supposed the rows number is 13, and columns number is 17.
So, the left top gain index should be 0, right top index be 16, left down index be [12*17], right down index be [13*17-1].
But, left top idx is set to , right top idx is set to , left down is set to , right down is set to .
I wonder what's the proper LSC gain table format requirements? so that I can use the lsc module properly.
