White Balance
White balance can be described as the reference color against which all
other colors in an image are compared. In considering the operational
aspects of the AXIS 200, the white balance is of particular importance.
You set the white balance parameter on the Configuration - Image
page.
The resident white balancing system within the AXIS 200 can
automatically detect white colors in any image, and use these
intelligently as a reference for other colors it views. In certain
situations, this system will not operate effectively.
Generally, problems will occur if the viewed image does not contain
any white color at all, or if the dominant color is something other than
white. In such circumstances, the AXIS 200 might erroneously base
the white balance on some other visible color in the scanned image.
Consequently, the colors may become distorted. A pale background
picture with foreground objects of an acute reddish or blue hue are
symptomatic of this condition. If this is the case, it is best to operate
the AXIS 200 in a fixed white balance mode.
White balance modes
You can specify one of these white balance modes:
Mode Description
Automatic The AXIS 200 uses the dominant color in the scanned image as
the white balance reference. This is the recommended mode.
Fixed outdoor This provides a standard white balance setting that is normally
suitable for outdoor use of the AXIS 200.
Fixed indoor This provides a standard white balance setting that is normally
suitable for indoor use of the AXIS 200.
Freeze The AXIS 200 uses a fix white balance that you establish
manually. See “Setting the white balance manually” on page 31..
Note that the setting will be lost when the AXIS 200 is powered
off.
