7.5 White Balance (on Color Models)
White balance capability has been implemented on color models of the camera. White balancing
can be used to adjust the color balance of the images transmitted from the camera.
With the white balancing scheme used on these cameras, the red intensity, green intensity, and blue
intensity can each be adjusted. For each color, a Balance Ratio parameter is used to set the
intensity of the color. If the Balance Ratio parameter for a color is set to a value of 1, the intensity
of the color will be unaffected by the white balance mechanism. If the ratio is set to a value lower
than 1, the intensity of the color will be reduced. If the ratio is set to a value greater than 1, the
intensity of the color will be increased. The increase or decrease in intensity is proportional. For
example, if the balance ratio for a color is set to 1.2, the intensity of that color will be increased by
20%.
The balance ratio value can range from 0.00 to 3.98. But you should be aware that if you set the
balance ratio for a color to a value lower than 1, this will not only decrease the intensity of that color
relative to the other two colors, but will also decrease the maximum intensity that the color can
achieve. For this reason, we don’t normally recommend setting a balance ratio less than 1 unless
you want to correct for the strong predominance of one color.
Setting the White Balance Using Basler pylon
Setting the Balance Ratio parameter for a color using Basler pylon is a two step process:
 Set the Balance Ratio Selector to red, green, or blue.
 Set the Balance Ratio Abs parameter to the desired value for the selected color.
This section (Section 7.5) describes how the camera’s white balance can be
adjusted "manually", i.e., by setting the value of the individual white balance
related parameters.
The camera also has a White Balance Auto function that can automatically adjust
the white balance. Manual adjustment of the white balance parameters will
only work correctly if the White Balance Auto function is disabled. For more
information about auto functions in general, see Section 7.8 on page 116. For
more information about the White Balance Auto function in particular, see
Section 7.8.7 on page 131.
Note that on cameras delivered from the factory, the exposure auto, gain auto, and
white balance auto (on color cameras) functions will all become enabled
whenever you power on or reset the camera. This behavior happens due to the
way that the camera’s configuration sets are set in the factory. More specifically, it
happens because the auto functions factory setup is selected as the default
configuration set and the default configuration set is designated as the "startup"
set. To change this behavior, you must change the configuration set settings. For
more information about configuration sets, see Section 7.19 on page 170.
