4.2.1 Exposure Mode
You can set the Exposure Mode to Global, BLC, HLC, or
DWDR.
• Global: The normal exposure mode, which performs
exposure according to the whole image brightness.
• BLC (Backlight Compensation): Compensates light
for the front object to make it clear, but may cause
overexposure of the background, where the light is
strong.
• HLC (Highlight Compensation): The camera detects
strong spots (overexposed portion of image), then
reduces the brightness of the strong spots to
improve the overall image.
• DWDR (Digital Wide Dynamic Range): The DWDR
helps the camera provide clear images even under
backlight circumstances. When both very bright
and very dark areas simultaneously exist in the
image, DWDR balances the brightness level of the
whole image to provide clear images with details.
4.2.2 Shutter
A photographic device that administers the exposure
by limiting the time over which light is admitted.
