Vertical & Horizontal Binning (2x2 Superpixels)
(... 5)
Steps 1 - 4

Vertical
Binning
of Two
Rows

4 Charge from two rows has already been vertically binned into the shift register
(see 'Vertical Binning of Two Rows', above). Now charge in the shift register
is moved horizontally by one pixel, so that charge on the endmost pixel of the
shift register is moved into the Gain Register, and subsequently into the output
node of the amplifier.)
5 Charge in the shift register is again moved horizontally, so that the output node
of the amplifier now contains charge from two pixels of the shift register - i.e.
the charge has been horizontally binned.
The charge in the output node of the amplifier is passed to the analog-to-digital
6
converter and is read out.
7 Steps 4 to 6 are repeated until the shift register is empty. The process is
repeated from Step 2 (again, see 'Vertical Binning of Two Rows', above) until
the whole frame is read out.
