Notes:
❏
From the AXIS 200+ Home Page, you can access the Image
Wizard that allows you to tune the image parameter settings
iteratively. See “ Stage 7. Adjusting the Image Parameters ” on page
19.
❏
If you use CGI parameters within a URL request, these
parameters will override any settings defined within the
Configuration - Image page. You will find more information on
the CGI parameters on page 59.
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+
automatically detects white colors in any image and uses these
intelligently as a reference for other colors. However, 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 another than white.
In such circumstances, the AXIS 200+ might erroneously base the
white balance on another visible color in the image. Consequently, the
colors will become distorted. A pale background picture with
foreground objects of an acute reddish or blue hue are symptomatic of
this condition. In this case, you are recommended 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
Normal Automatic color adjustment. The camera tries to find a white area
in the image within normal limits.The color in the identified area is
defined as white and all other colors are adjusted proportionally.
Automatic
Narrow Automatic color adjustment. The camera tries to find a white area
in the image within narrow limits. The color in the identified area
is defined as white and all other colors are adjusted
proportionally. If the camera cannot identify such a white area,
the automatic color adjustment is turned off.
