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”.
GenICam Parameters
BlackLevel[Black Level Selector]
IFloat Type
Black Level, Default: 7 (on 8bits output)
Range:
8bits output: 0 to 31
10bits output: 0 to 127 (10bits Packed outputs same as this mode)
12bits output: 0 to 511 (12bits Packed outputs same as this mode)
9.7
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.
GenICam Parameters (for AGC and Auto Exposure)
AutoLightTarget
Integer Type
Target Brightness
Range: 0 to 255, Default: 127
Target Brightness Formula (Auto Light Target)
8bits output: Target Brightness (Gradient)
＝
Auto Light Target
10bits output: Target Brightness (Gradient)
＝
Auto Light Target × 4
12bits output: Target Brightness (Gradient)
＝
Auto Light Target × 16
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 adjust 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.
