USING SPECIAL FEATURES

Lens adjustment

You may adjust the focus and zoom of the lens to bring the object in focus.

This lens has two focal distances. The change of Tele/Wide can be done with

zooming. You could switch focus between Tele/Wide, by re-adjusting focusing once again.

Back Light Compensation

When BLC is turned on, the AGC, ES or 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.
