Charge-coupled device 電偶設備的功用
Re: Charge-coupled device 電偶設備的功用
Charge-coupled device 即CCD，是數碼攝影機及攝錄機常用的感光元件，另一種常用感光元件是 CMOS (Complementary Metal Oxide Semiconductor)。梅西爾 寫:Charge-coupled device 電偶設備有何功用？

如來如此，
多謝你的提醒，
低是那種故好用？

那CCD(Charge-coupled device)與CMOS (Complementary Metal Oxide Semiconductor)的分別在那裡？CHYeung 寫:Charge-coupled device 即CCD，是數碼攝影機及攝錄機常用的感光元件，另一種常用感光元件是 CMOS (Complementary Metal Oxide Semiconductor)。梅西爾 寫:Charge-coupled device 電偶設備有何功用？

Attached two figures from the 2nd link: CCD vs CMOS: Facts and Fiction by Dave Litwiller
In CCD, electronic circuit push/shift roll of electric charges to the bottom row. Again, electronic circuit push/shift each cell of charge of the bottom row out of the CCD for detection.
In CMOS sensor, pixel is selected by electric circuit and the voltage level is then detected inside the chips. The voltage of the pixel is then represented out by digital figure.
(*** In generally, CMOS (互補式金屬-氧化層-半導體) is only a kind of digital IC circuity or manufacturing method http://zh.wikipedia.org/w/index.php?tit ... iant=zh-hk )
CCD was invented for imaging in 1969. (http://www.dpreview.com/news/0601/06010 ... esmith.asp)
CMOS was applied for imaging only in recent years. (excluding CMOS light sensor)
There are some links about CCD vs CMOS
