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): 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.
4.2.3
AGC (Automatic Gain Control)
Optimizes the clarity of the image in poor light
conditions. The AGC level can be set to HIGH, MEDIUM,
or LOW.
The noise will be amplified when setting
the AGC level.
