•
Back Light - Backlight compensation (BLC) adjusts the picture in
situations where a bright light source, such as window, is causing the
image to be improperly exposed.
•
Low Light Presets - There are a lot of controls in determining
how the camera behaves in low light conditions. To simplify low
light use, a number of Low Light Presets are available to instantly
configure the camera as required. The presets automatically set
all the other controls. If you'd like to manually set the advanced
controls select "Manual" in the Low Light Presets dropdown.
•
Exposure Limit - The camera will not expose the image sensor
above this value. The default is 32767 (about 0.7 seconds). A higher
value will make the camera more light sensitive in low light at the
expense of motion blur.
• Allow Extended Exposures - In darker lighting conditions, a
longer exposure produces a brighter image. A longer exposure also
produces an image where objects in motion may appear blurry. If
your application requires the best possible image quality and motion
blur is not a concern, enable Allow Extended Exposures and set the
Exposure Limit to a high value (up to 32767). If your application
requires capturing images of people or objects in motion, disable
Allow Extended Exposures.
•
Automatic Gain Control (AGC) - The picture is digitally
amplified in low light conditions or in situations where the exposure
is limited to reduce motion blur. Enabling AGC may introduce image
noise.
• AGC Limit - The higher the limit, the more digital amplification
occurs (assuming it's necessary). If you want to limit the digital gain
to reduce noise on the image, reduce this value.
• Low Light - In low light conditions, the analog low light mode of
the image sensor is enabled. Enabling Low Light may introduce
image noise.
• Pixel Rep - Groups pixels together for better light sensitivity, at the
expense of image clarity.
•
DNR (Digital Noise Reduction) - Reduces image noise using
digital algorithms.
• Image Speed - Determines when low light gain is initiated in
relation to the exposure.
•
Alternate YUV - Uses non-standard algorithms to process color,
allowing for improved light sensitivity.
