The inclusive window refers to “weighted window“; the exclusive window refers to “ignored window“. It
adopts the weighted averages method to calculate the value.
■ BLC (Back Light Compensation): This option will automatically add a “weighted region“ in the middle of
the window and give the necessary light compensation.
Exposure control:
■
Exposure level: You can manually set the Exposure level, which ranges from -2.0 to +2.0 (dark to
bright).
■ Flickerless: Under some circumstances when there is a difference between the video capture
frequency and local AC power frequency (50Hz or 60Hz) due to the electronic rolling shutters of CMOS
sensor, the mismatch causes color shifts or ickering images. If the above mismatch occurs, select the
Flickerless check-box, and the range of Exposure time will be limited to a range in order to match the AC
power frequency. See the screen capture below.
You can click and drag the semi-circular pointers on the Exposure time and Gain control slide bars
to specify a range of shutter time and Gain control values within which the camera can automatically
tune to an optimal imaging result. For example, you may prefer a shorter shutter time to better capture
moving objects, while a faster shutter reduces light and needs to be compensated by electrical
brightness gains.
NOTE
* In a setup of Exposure time and Gain control, do not set maximum and minimum value as equal.
