Och då är det inte "samma teknologi", eller hur?
Det är väl aldrig "samma teknologi" i två olika sensorer...
Här kommer några tankar om cmos-utvecklingen med synpunkt från just Eric Fossum, från nov 2008.
"Now, experts say, CMOS imaging technology is developing much faster than CCD, partly because CMOS
imaging chips are built with the same basic processes used in producing other kinds of semiconductors,
like memory chips and processors. CCDs, by contrast, are less familiar to the majority of semiconductor
New Chips Poised to Revolutionize Photography, Film engineers.
And thanks to Moore's Law, the power and speed of semiconductor technology keeps increasing
exponentially. That means CMOS image sensors are getting better and better, incorporating more
sophisticated noise compensation, shrinking the size of the gaps between each light-gathering pixel that are
devoted to wiring and other electronics, and adding image and video processing features to the chips
themselves.
"I'm amazed myself at how quickly the tech developed a life of its own and how fast it's evolving," says Eric
Fossum, an entrepreneur and engineer who developed the type of CMOS imaging technology used in most
modern cameras while he was a researcher at NASA's Jet Propulsion Laboratory in the early 1990s. "It's
kind of mind blowing to me." "
