Tech-On: Ericsson AB of Sweden revealed its efforts in LTE mobile standard promotion at a press conference Nov 6, 2008. During the conference, Ericsson mentioned its concept of a future mobile terminal as "a mobile device in 2012." According to the concept, high-function terminals, in the future, will be equipped with a 12- to 20MP camera and support full HD video shooting capability.
Assuming the "2012 mobile device" has 1/3" sensor, this translates to 1.1um (12MP) or 0.8um (20MP) pixel pitch. As for 1.1um pixel, it's probably safe to assume that it will be mass produced sometime in 2012. I'm less sure about 0.8um generation. Probably Ericsson AB is more optimistic than me on the time table of the image sensor industry. One needs a real leapfrog to make 0.8um in 2012.
