使用DCC调整DM8127中GAMMA,生成的GAMMA表中数据含义?



本人在用DCC调整DM8127中ISP功能,GAMMA插件会生成Generated_Gamma_file0002.txt这个文件,

文件中有两列数(大小512*2)

0,4,
4,4,
8,4,
12,4,
16,4,
20,4,
24,4,
28,4,
32,4,
36,4,
40,8,
48,4,
52,4,
56,4,
60,8,
68,4,
72,4,
76,8,
84,4,
88,8,
96,4,
100,8,
108,4,
请问有人明白数字的含义吗?

还有公式

LUT[index]/1024 = (index*8/4096)^(gamma).

slope[index] = LUT[index+1] – LUT[index] 

可以生成GAMMA表的两列数据,请问具体含义是什么?

谢谢~~
