Weighted region Ignored region | Vivotek FD8169 instruction

VIVOTEK

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). 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. 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.

■Flickerless: This function helps avoid the flickering on images because of the fast shutter movement and the inconsistency between power line frequency (50 or 60Hz) and exposure time.

When selected, the exposure time will be forced to stay longer than 1/120 second. For cameras that come with fixed iris lens, setting the exposure time to longer than 1/120 second may introduce too much lights to the lens. Users can use this option to observe whether the result of long exposure time is satisfactory.
