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 sam-
ples shall be equal; i.e., it assumes that the average of the sampled grid pix-
els 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.
