Measurement Window: This function allows user to set measurement window(s) for low light

compesation�

■ Full view: Calculate the full range of view and offer appropriate

light compesation�

■ BLC (Back Light Compensation): This option allows you to use the center of the current view

as the measuring area� The measuring window refers to “weighted window“ where the lighting

condition within the particular area is taken into account� Camera firmware then adopts the

weighted averages method to calculate the value and provides necessary light compensation�

Exposure control:

■

Exposure level: You can manually set the Exposure level, which ranges from 0 to 8 (dark to

bright)�

■ Flickerless

: This function helps avoid the flickering on images because of the fast shutter

movement� When selected, the exposure time will be forced to stay longer than 1/120 second�

■

Exposure time: you can split the round pointers on the Exposure time and Gain control slide

bars into two halves and drag them on the bars to designate a range of values in which rmware

can automatically adapt to� Note that Firmware will then automatically tune the Gain, Exposure

time, and Iris opening within the ranges you specied. For example, in low-light condition, you

may prefer a longer exposure time and more electronic gains� However, the noises in the image

will also increase�

■

Gain control: Tune the slider bar to set the Gain Control to the best image quality� Higher gain

control value will generate a certain amount of noises, and that the gain control, lighting levels,

and picture performance are closely related�
