In the LEVEL option, you can adjust the overall brightness.

In the BACKLIGHT option, you can adjust the BLC(Back Light Compensation) function
to improve the sharpness of the image in a high contrast scene.
If you select the BACKLIGHT option to WDR*, you can adjust the shutter speed in

SHUTTER : OFF, AUTO1/100(120)~1/10K, 1/100(120)~1/10K
You can select one of the 7 options from 1/100(PAL : 1/120) to 1/10K for the fixed high
speed electronic shutter, which is mostly used for snapping a fast moving object. The
auto high speed electronic shutter operates as the fixed high speed shutter in a high
contrast scene but automatically focuses the target if the iris opens fully in a low
contrast scene like in ELC mode. When it gets bright again, the mode will switch to the
fixed high speed electronic shutter mode.
