BACKLIGHT COMPENSATION (BLC)
If a bright backlight is present, the subjects in the picture may appear dark or as a silhouette.
Backlight compensation enhances objects in the center of the picture. The dome uses the center
of the picture to adjust the iris. If there is a bright light source outside of this area, it will wash
out to white. The camera will adjust the iris so that the object in the sensitive area is properly
exposed.
There are two backlight compensation settings:
ON Backlight compensation is activated.
OFF (default) Backlight compensation is not activated.
NOTE: If backlight compensation is ON, decrease the Auto Iris setting and adjust the Auto IR
Level to a darker setting. Refer to the
Auto Iris
and
Auto Iris
Level
sections.
*This setting only applies to
Pressurized Spectra III dome
systems with software version
1.27 or higher.
