68 - User's Manual
■ Custom: This option allows you to manually add customized windows as inclusive or exclusive regions.
A total of 10 windows can be set.
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).
■ Exposure time: The Exposure time allows tuning for more or less light to enter the lens. The
configurable value ranges from 1/32000 to 1/5 of a second. An optimum shutter speed should be
maintained as long as the light level of the scene permits.
■ Gain control: Selects the reasonable gain value to maintain a good imaging quality. Note that the gain
control, lighting levels, and picture performance are closing related.
