■BLC: When selected, a BLC window will appear on screen meaning that the center of the scene will be taken as a weighed area. This option enables light compensation for images that are too dark or too bright to recognize; for example, for the dark side of objects that is posed against bright sunlight.
Exposure control:
■Exposure level: You can manually set the Exposure level, which ranges from 0 to 8 (dark to bright). 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.
■Maximum 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 noise.
WDR Pro: This function allows users to identify more details of objects in the high contrast environment especially for details in the shaded area. This feature is enabled by default. You may select or deselect the Enable WDR Pro checkbox, and then adjust the strength (low, medium, high) to reach the best image quality depending on the lighting conditions.
