White Balance
White Balance parameters give you control over the individual red, green, and blue colors
produced by the sensor in color cameras.

values:
•
Off
– No white balance is performed.
•
Once
– The camera analyzes one image frame, calculates one set of correction
coefficients, and corrects all subsequent frames using this set of coefficients.
•
Continuous
– The camera analyzes every frame, derives a set of correction
coefficients for each frame, and applies them to the next frame.
•
Manual
– The camera uses the correction coefficients as entered from the user.
The range is from 0 to 4095 (0 is equal to 0.0x, 256 is equal to 1.0x, 4095 is equal
15.995x gain).
