ALC (Auto Light Control)
ALC function has two control methods, which is AGC (Auto Gain Control) and the auto shutter. The AGC and the auto
shutter sets up individually.
The camera parameters are adjusted to the brightness of the image is maintained with the target brightness
automatically with the ALC function.
GenICam parameters (for AGC and auto shutter)

Target brightness (TargetBrightness) formula
At 12bits output: Target brightness (grayscale) = TargetBrightness * 16
At 10bits output: Target brightness (grayscale) = TargetBrightness * 4
At 8bits output: Target brightness (grayscale) = TargetBrightness
About the importance ratio for the brightens peak at ALC control (ACL_Peak_Average)
When 0 sets, Average: 100%, Peak: 0%. The ALC control with the brightness average.
When 255 sets, Average: 0%, Peak: 100%. The ALC control with the brightness peak.
When 128 sets, Average: 50%, Peak: 50%.
