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?

This article seems biased toward CMOS sensors over CCD sensors, as it touts CMOS's improved speed and cheaper cost, but does not include information regarding CMOS's greater susceptibility to noise over CCDs (especially in low light conditions).

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]
