Back Light Compensation

When BLC is turned on, the AGC, ES and IRIS operating point is determined by
averaging over the center area instead of entire field-of-view, so that a dimly-lit
foreground object at center area can be clearly distinguished from brightly-lit
backgrounds.
BLC should not be used unless it is needed to compensate for back-lit
