Wide Dynamic Range
Wide dynamic range (
Dynamic Contrast
) can improve the exposure when there is a considerable contrast between light and dark
areas in the image. Enable WDR in intense backlight conditions. Disable WDR in low light conditions for optimal exposure.
Note
This setting is only possible when using automatic exposure control.
Exposure Settings
Configure the exposure settings to suit the image quality requirements in relation to lighting, frame rate and bandwidth
considerations.
Exposure value -
Click in the bar to fine-tune the exposure.
Exposure control -
These settings is used to adapt to the amount of light used.
Automatic
is the default settings can be used in most
situations. The shutter speed is automatically set to produce optimum image quality.
Flicker-free 50 or 60 Hz
is used to remove
flicker which can be caused by fluorescent and other light sources. The
Hold current
option locks the current exposure settings.
Enable Backlight compensation -
Enable this option if a bright spot of light, for example a light bulb, causes other areas in
the image to appear too dark.
Exposure zones -
This settings determines which part of the image is used to calculate the exposure. For most situations, the
Auto
setting can be used. For particular requirement, select a predefined area.
Shutter & Gain
The shutter and gain settings affect the amount of motion blur and noise in the image. To adapt to different lighting, available
storage space and bandwidth, it is often necessary to prioritize either low motion blur or low noise. The Axis product allows
using different prioritization in normal light and in low light.
Shutter speed
is related to the amount of time the shutter is opened and is measured in seconds (s). A slow shutter speed allows
more light to reach the sensor and can help produce a brighter image in low light situations. On the other hand, a slow shutter
speed can cause moving objects to appear blurry.
Set
Shutter
to
•
Auto
to set the shutter speed automatically. If required, use
Max shutter
to limit the shutter speed to prevent the frame
rate from being reduced.
For example, to get 30 fps, set Max shutter to 1/30.
•
Fixed
to use a fixed shutter speed.
Gain
, measured in decibel (dB), is the amount of amplification applied to the image. A high gain may provide a better image in low
light situations but will increase the amount of image noise.
Set
Gain
to
•
Auto
to set the gain automatically. If required, use
Max gain
to limit the applied gain.
•
Fixed
to use a fixed gain.
When
Shutter
and
Gain
are both set to
Auto
, it is possible to set the
Priority
between low motion blur and low noise manually and to
use a different
Priority
in
Normal Light
and in
Low Light
.
Example
Consider an area where people or vehicles move during the day, but where there should be no movements during night. To be able to,
for example, recognize faces or license plates, move the normal light priority slider toward low motion blur. At nighttime, motion
detection is more important than identification. Motion blur is acceptable and since low light can cause a lot of noise, move
the low light priority slider toward low noise.
