Full Frame Mode
In this operation mode, the entire sensor shown in
sequencer, and the behavior of the data and sync channels (overview and detail of one line).
Off Chip Automatic Black Level Calibration
The last time slot not only contains valid pixels but also two
dummy columns, six grey columns, and eight black columns.
The grey column values are used to perform off chip black level
calibration to maintain a constant black level against any type of
drift. These values gauge the response of normal pixels in the
dark conditions.
Grey columns are generated by applying a minimal integration
time (black timer register) to the columns. Black columns share
the same minimal integration time; additionally, the pixels in that
column are shielded. Grey columns can be used if the integration
time is large compared to the minimal integration time. Black
columns are used if the integration time is in the same order of
magnitude as the minimal integration time.

The procedure is as follows:
1. Decide what digital code should be the desired black level.

Make sure that the grey (or black) columns can be read out
without clipping.
Make sure that this is the case for every sensor including
dc-shifts due to Vt and temperature differences.
