什麼是CMOS

What is CMOS?

 

CMOS(Complementary Metal Oxide Semiconductor)是“互補式金屬氧化物半導體”元件的縮寫。和較為廣泛使用的CCD(Charge-coupled Device電荷耦合元件)相比,這是一種較新式的感光元件。概略的說,CCD耗電量較大,CMOS的雜訊較高,但是在數位影像技術突飛猛進的今天,這兩種元件的差異已經相當的小。所以廠商可以自由根據相機的整體設計來選擇適用的感光元件。

Complementary Metal Oxide Semi-conductor (CMOS) is a type of light sensor that is used by manufacturers as an alternative to the more wide spread Charge-Coupled Device (CCD) sensor types. In very broad terms CCD sensor types exhibit a higher power consumption compared with CMOS designs, but conversely CMOS sensor have an inherently higher electronic noise level. However, in truth digital imaging technology is advancing so fast that such differences are becoming blurred so much so that a manufacturer will use whichever sensor type they deem most appropriate for their camera design.

迄今(本文發稿)除了D2H之外,尼康數位單眼都是使用CCD元件。D2H用的是一種混合式的CMOS感光板。它包括了耗電量極低的JFET和LBCAST(側向電荷累積感光陣列)。D2X則是尼康第一台使用標準的CMOS感光元件的數位單眼。

To date Nikon have used CCD sensors in their D-SLR cameras, with the exception of the D2H model, which uses a hybrid CMOS sensor of their own design known as the Joint Field-Effect Transistor (JFET) Lateral Buried Charge Accumulator and Sensing Transistor array (LBCAST) imaging sensor. The JEFET portion refers to the very low power consumption characteristics of this particular sensor type, and the LBCAST refers to the way in which it accumulates and stores image data. The D2X was the first Nikon D-SLR to use a standard CMOS type sensor.
