That last comment must both be generating amounts of saliva dwarfing the throughput of Niagara falls while sending shrivers of concerns in more than a few camera company HQs...
For sure :p
Over the world many ppl think that the new sensor is not a "true" Foveon anymore, and they are wrong.
It is still a full 3 layers sensor. Just look at the picture below :
The signal is captured on the 3 layers, as usual.
The thing is that the GREEN and RED layers have much bigger pixels, 4 pixels binned in one. That is done for the CAPTION part.
The signal after processing is pretty simple, without any interpolations as some said: This is division of the GREEN and RED layers in a certain %age, after the caption.
The whole trick is in the binning technology.
The RED and GREEN layers have the same surface as the Blue layer : 23.5×15.7mm
On top of that, we go from 15 MP To 20 MP, 30% more resolution.
