The values in the
U/B_Value
field produce changes from green to blue; the
V/
R_Value
field from green to red as illustrated below.
The increment length is
~0.0353 dB/step.
One-push white balance
The camera automatically generates frames, based on the current settings of
all registers (GAIN, OFFSET, SHUTTER, etc.).
For white balance, in total
9
frames are processed. For the white balance
algorithm the whole image or a subset of it is used. The R-G-B component
values of the samples are added and are used as actual values for the
one-push
white balance
.
This feature uses the assumption that the R-G-B component sums of the
samples shall be equal; i.e., it assumes that the average of the sampled grid
pixels is to be monochrome.
Note
While lowering both U/B and V/R registers from 284 towards 0,
the lower one of the two effectively controls the green gain.
