The increment length is ~0.0353 dB/step.
One-push automatic white balance
To configure this feature in control and status register (CSR): See Table 43:
White balance register on page 105.
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 both the
one-push and the automatic 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
L
The following ancillary conditions should be observed for suc-
cessful white balance:
• There are no stringent or special requirements on the
image content, it requires only the presence of mono-
chrome pixels in the image.
• Automatic white balance can be started both during
active image capture and when the camera is in idle
state.
