AXIS Q9216-SLV Network Camera
The device interface
Wide dynamic range
WDR
: Turn on to make both bright and dark areas of the image visible.
Local contrast
: Use the slider to adjust the contrast of the image. A higher value makes the contrast higher between dark
and light areas.
Tone mapping
: Use the slider to adjust the amount of tone mapping that is applied to the image. If the value is set to zero only
the standard gamma correction is applied, while a higher value increases the visibility in the image.
White balance
When the camera detects the color temperature of the incoming light, it can adjust the image to make the colors look more
natural. If this is not sufficient, you can select a suitable light source from the list.
The automatic white balance setting reduces the risk of color flicker by adapting to changes gradually. If the lighting changes, or
when the camera is first started, it can take up to 30 seconds to adapt to the new light source. If there is more than one type
of light source in a scene, that is they differ in color temperature, the dominating light source acts as a reference for the
automatic white balance algorithm. This behavior can be overridden by choosing a fixed white balance setting that matches
the light source you want to use as a reference.
