Black Level
This parameter sets the black level (the clamp level for the black signal).
Sets the black level at “BlackLevel[Black Level Selector]”.
The lower limit of the signal is clamped at this setting level. The signal does not lower than this.
(*) “Analog All” is only selectable at “Black Level Selector”.

ALC (Auto Light Control)
ALC has AGC (Auto Gain Control) and auto exposure function. It can be set individually.
The camera parameters adjust automatically based on current brightness of image, to achieve the target brightness
with ALC function.

9.8.1 ALC Control Method
The brightness of image adjusts to achieve “Auto Light Target” brightness with AGC and auto exposure function.
When AGC and auto exposure are enabled, at first, the brightness adjusts with auto exposure function. If the
brightness does not achieve “Auto Light Target” brightness with auto exposure function, the brightness adjusts
with the AGC function.
