BLC: Backlight Compensation (BLC) is used to compensate AGC in
adjusting color intensity. For scenes with strong light in the
background and dim light in the foreground, AGC is not effective
because AGC averages the light intensity of a whole frame. BLC
compensates for this characteristic by restricting AGC to adjust color
intensity of a specific area. To turn on, use the drop-down list, select
On , and select a level among 0 to 7. A higher value indicates a
stronger compensation effect.
