See: http://1000nerds.kodak.com/default.asp?item=664294 David I would question the statement that CCDs were first designed specifically for cameras. Wasn't the analog delay line the first use of CCDs? The linear array CCD came along before the 2D matrix. |

What I did find interesting was the different emphasis being put on the reasons behind using CMOS - not because it provides a higher image quality, but because it makes for a cheaper system, and that the quality has only recently become "acceptable" for small sensors.

David Maybe they realize a policy of honesty will draw more support. |

But it could be the case. For one thing, "designed/developed" and "commercially available as a product" also are different things. :-) Back in the days of CCD's as analog delay lines (for low cost consumer applications) I know they were built (2" wafers I think, but could have been 1") for camera applications for telescopes by Tektronix (probably as part of Teklabs, in obviously small quantities). More of a research project (Teklabs back then was much like Bell Labs where they did pure research just for the pure science of it, not product related). So I don't know it to be true, but CCD's as camera devices could very well have happened before analog delay line applications -- at least in the lab that made them originally. |
