Here is a video from Sony\'s Hugo Gaggioni discussing discussing Sony\'s sensor technology. Starting at 22:14 he talks about CDS (Correlated Double Sampling) and how it\'s used to normalize reset noise. At 24:30 he talks about Sony\'s digital CDS implementation and how it eliminates the banding seen on competing analog CDS designs. The context is for video broadcast technology but is applicable to both their Video and Still products. Sony calls this their EXMOR technology and I believe the first DSLR sensor to utilize it was their 12MP sensor in the A700 and derivatives for the Nikon D90/D5000, followed by the 16MP variant in the D7000/D5100/K5 and 16MP alphas.
One thing I wonder is if all that stuff is under Sony Patent and if there is any other way to match their low ISO DR, if not, we may be stuck for a long while with much worse DR. I hope not.
Very interesting video, thanks for sharing, snapsy. You both are right, \"if all that stuff is under Sony Patent\" then it will be a very long long long time for Canon to get rid of the pattern banding noise.... i wish we have 1dx raw black frame to check the latest Canon processing.
