Any idea how this can happen (except by some very effective image
processing before doing anything else to the raw data)?

There may be some specific noise suppression in the DIGIC processor
as well, but at least it is not obvious (apart from the absence of
noise).

Most of it is in the much inproved photo-diode resetting in CMOS
units, and using double correlation read-outs.


However, the S70, which has a CCD, also has extremely low readout noise.
This was the point of the question.
