The inclusive window refers to the “weighed window“; the exclusive window refers to “ignored window“. It adopts the weighed averages method to calculate the value. The inclusive windows have a higher priority. You can overlap these windows, and, if you place an exclusive window within a larger inclusive window, the exclusive part of the overlapped windows will be deducted from the inclusive window. An exposure value will then be calculated out of the remaining of the inclusive window.

■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 (NTSC or PAL), the mismatch causes color shifts or flickering images. If the above mismatch occurs, select the Flickerless checkbox, and the range of Exposure time (the shutter 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 automaticallly 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.
