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)

Sensors used in digital cameras (table)

1. Given the vast number of digital cameras available, each with different sensor/filter/architecture configurations, I can't see how this "product comparison" table could ever hope to achieve its goal! 2. IMO, the data it contains is too specific for this article, and takes up a lot of screen space. Please may I remove it ? --Redbobblehat (talk) 13:51, 15 February 2011 (UTC)

Good luck with that, many people place a lot of faith in counting pixels and considering sensor areas. If anything, may I suggest creating another page called "List of electronic image sensor configurations"? Ehusman (talk) 03:07, 16 February 2013 (UTC)
I had the same thought, and just moved the info. Timtempleton (talk) 01:49, 28 April 2017 (UTC)

Sensors for security cameras, best sensor for specific purposes

I've read more than once that one type of sensor (that is, either CMOS or CCD) is better for security cameras in that it can capture colors better in low light conditions. (Of course, that may change as either technology advances.) Still, I'd like to suggest / request that a section be included (possibly a table) that does something like list which technology is better for specific applications (maybe security cameras, point and shoot cameras, cell phones, high end cameras, video cameras, and maybe separating into categories like low light applications, high resolution applications, or something similar).
