Highlight Compensation Menu (HLC)
LEVEL:
Sets when highlights will be masked. The lower the value, the lower the
required luminance value will be for the camera to mask it, and thus the more
areas of the screen will be masked.
MODE:
You can choose when HLC will be active.
ALL DAY
will leave HLC on
at all times, whereas selecting
NIGHT ONLY
will leave highlights during the day
unaffected - this is a good option if you’re looking to mask, for example, car
headlights or an inconveniently placed street lamp.
