gammacurve

dependent>
0~100
4/4
0: Fine-turned gamma curve by
Vivotek.
1: Gamma value = 0.01
2: Gamma value = 0.02
3: Gamma value = 0.03
...
100: Gamma value = 1
* Note: Although we set gamma value
to 100 level, but not all gamma values
are valid. Internal module will take the
closest valid one. For example, 1~45
may all be mapped to gamma value =
0.45, etc.

"capability_image_c<0~(n-
