Method
WDR It is intended to provide clear image
performance in strong backlight areas such as
exterior light coming through a window or
glass door. High contract light conditions are
no longer a problem when you need to
capture detailed images. [Setting method]
Drag the slider.
[Default value]
50
HLC It indicates reverse bright points in the picture
to black. As an effective approach to
recognize vehicle plate number at night, HLC
function can detect any spotlight diffused by
object-vehicle and compensate it for
obtaining clearer image. [Setting method]
Drag the slider.
[Default value]
50
BLC It indicates Back Light Compensation (BLC)
automatically brings more detail to darker
areas of an image when bright light shining
from behind obscures it and provides perfect
exposure for an object in front of very strong
back light. The electronic shutter of the
camera basically adjusts its exposure to try to
allow for more light to be allowed in the
darker areas.
This parameter applies only to visible light.
[Setting method]
Drag the slider.
