How is this analog?
"Each cell of a CCD image sensor is an analog device. When light strikes the chip it is held as a small electrical charge in each photo sensor". How is this analog? The photoelectric effect is literally the starting point of quantum mechanics, exchanging a quanta of light for a charge carrier (see Einstein 1905 and his Nobel prize 1921). The info and explanation in the article are the kind of things you would get from a guy at your local electronics store: lots of numbers and no actual understanding. Pixel counts are also a relatively low grade of information for an encyclopedia page, more useful would be a plot of pixel count in time and 2-3 notable milestones.

- It's analog because there is no way to count the photoelectrons; instead, the charge is measured via an analog voltage. Dicklyon (talk) 03:04, 8 March 2017 (UTC)
