Use the White Balance drop-down menu to select a white balance preset:
White Balance Presets
Descriptions
Off
No white balance performed.
Once
The camera analyzes only one image frame, calculates only one
set of color correction coefficients, and corrects all subsequent
frames with this set of coefficients.
Auto
The camera analyzes each frame, derives a set of correction
coefficients on each frame, and applies them to the next frame.
Manual
The camera uses the correction coefficients as entered from the
user.
Table 4: White balance presets
Use Manual WB Coefficients to manually define white balance coefficients for each color
(red, green, and blue). Coefficient values affect the intensity of each color and range from
0 to 4095. The Statistic area of the screen gives you the current (calculated) white balance
coefficients per color.
For best color accuracy and stability when the spectral source is constant, image a
uniform grey target with the camera using a desired light source. Select
Once
to find the
correct R, G, and B coefficients and write down the values. Then select
Manual
and load
these coefficients into the camera. Leave Manual selected. The camera will now apply
these coefficients to every frame captured.
