Image sensor comparisons

A comparison of image sensor characteristics might encompass "Human Eyes as Image Sensor"[1], Fukui, Y. (2002?). --Redbobblehat (talk) 20:51, 13 February 2009 (UTC)[reply]

Shooting video

Why is there no explanation of these new sensors ability to shoot video?

I would like to know more about it. —Preceding unsigned comment added by 69.154.215.222 (talk) 19:17, 1 June 2009 (UTC) Videos are just images captured at a high rate and put together, and the article mentions speed (CMOS > CCD). This is actually one reason among others why CMOS has begun to vastly overtake CCD in digital imaging. —Preceding unsigned comment added by 129.97.120.206 (talk) 23:29, 30 March 2010 (UTC)[reply]

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)[reply]

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)[reply]

I had the same thought, and just moved the info. Timtempleton (talk) 01:49, 28 April 2017 (UTC)[reply]

Companies

In the list of companies that manufacture image sensors - do all of the companied listed actually manufacture them? For instance I thought Nikon only designs their sensors (or modifies other designs) and then gets other companies to do the actual manufacturing. This needs clarifying. — Preceding unsigned comment added by 202.89.25.245 (talk) 03:06, 26 September 2013 (UTC) I don't think that the companies that manufacture image sensors should be included in the article at all, unless it has a strong relation with the actual description of an image sensor. — Preceding unsigned comment added by 194.98.70.135 (talk) 14:33, 12 August 2014 (UTC)[reply]

Article needs improvement

This article is not very useful because it does not clearly explain how image sensing is done. I don't see the need for having a huge table with sensor names and sizes when what the article really needs is a section that unveils the technology (possibly before making the CCD/CMOS technology comparison).

This section is somewhat unclear: "Neither technology has a clear advantage in image quality.^{[citation needed]} On one hand, CCD sensors are more susceptible to vertical smear from bright light sources when the sensor is overloaded; high-end CMOS sensors in turn do not suffer from this problem. On the other hand, cheaper CMOS sensors are susceptible to undesired effects that come as a result of rolling shutter.^{[citation needed]}". Also, what would be the source of the overload?

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. Fincle (talk) 17:27, 16 June 2016 (UTC)[reply]

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)[reply]
