White Balance:
Sets the White balance mode of operation.
1.
“Off” – No white balance is performed.
2.
“AWB Once” – the camera analyzes only one image frame,
calculates only one set correction coefficients, and all
subsequent frames are corrected with this set of coefficients.
3.
“AWB Tracking” – the camera analyzes every frame, a set of
correction coefficients are derived for each frame and applied
to the next frame.
4.
“Manual” – the camera uses the correction coefficients as
entered from the user.
Manual WBC:
The user enters manually the white balance coefficients for each
color. The range is from 0 to 255 (255 is equal to 1.0x). The user
has option to set all coefficients to “Zero”.
Tracking Speed:
For Auto-White Balance (AWB), the user has the option of
selecting from five update rates. When 1x is selected, the AWB
algorithm responds slowly to any changes in the scene
illumination whereas 5x tracking provides most responsiveness.
Manual WB:
The user can set individually the desired digital gain for each
primary color R G B (1.0x to 4.0x, 0.001x increment) via the
arrows or by entering the desired value. The user has option to
set all gains to “Unity” (1.0x)
