title="監控攝像機">監控攝像機來說，CCD是最核心的部件，相當于監控攝像機的眼睛?，F階段CCD芯片市場如何？
按照成像色彩、分辨率、靈敏度以及靶面尺寸的不同有不同的分類。一般來說，大的CCD芯片，其相應的象素面積也較大，接收所攝光的面積增大，必然使象素輸出電荷增多，靈敏度上升，在弱光條件下具有較好的拍攝能力，容易使攝像機整體質量提高，圖像細部明顯細膩自然。而光學系統聚焦影像時的焦平面越小，則成像過程中丟失的細節就越多，得到的影像放大后細部過渡就可能有突變的現象，顯得不自然。
另外小尺寸CCD擁有更多的象素和更高的分辨率也會導致單個像素的感光面積縮小，有曝光不足的可能。單個像素的面積越小，其感光性能越低，信噪比越低，動態范圍越窄。每個象素上的信息趨于與在它附近的象素的信息混合(在電子學上這個概念叫做色度亮度干擾)。
CCD與CMOS的比較
互補性氧化金屬半導體CMOS(ComplementaryMetal-OxideSemiconductor)和CCD一樣同為在數碼相機中可記錄光線變化的半導體。CMOS的制造技術和一般計算機芯片沒什么差別，主要是利用硅和鍺這兩種元素所做成的半導體，使其在CMOS上共存著帶N(帶-電)和P(帶 電)級的半導體，這兩個互補效應所產生的電流即可被處理芯片紀錄和解讀成影像。然而，CMOS的缺點就是太容易出現雜點，這主要是因為早期的設計使CMOS在處理快速變化的影像時，由于電流變化過于頻繁而會產生過熱的現象。
CCD與CMOS不同工作原理
由兩種感光器件的工作原理可以看出，CCD的優勢在于成像質量好，但是由于制造工藝復雜，只有少數的廠商能夠掌握，所以導致制造成本居高不下，特別是大型CCD，價格非常高昂。
在相同分辨率下，CMOS價格比CCD便宜，但是CMOS器件產生的圖像質量相比CCD來說要低一些。CMOS感應器則作為低端產品應用于一些攝像頭上。
CMOS影像傳感器的優點之一是電源消耗量比CCD低，CCD為提供優異的影像品質，付出代價即是較高的電源消耗量，為使電荷傳輸順暢，噪聲降低，需由高壓差改善傳輸效果。但CMOS影像傳感器將每一畫素的電荷轉換成電壓，讀取前便將其放大，利用3.3V的電源即可驅動，電源消耗量比CCD低。
CMOS影像傳感器的另一優點，是與周邊電路的整合性高，可將ADC與訊號處理器整合在一起，使體積大幅縮小，例如，CMOS影像傳感器只需一組電源，CCD卻需三或四組電源，由于ADC與訊號處理器的制程與CCD不同，要縮小CCD套件的體積很困難。但目前CMOS影像傳感器首要解決的問題就是降低噪聲的產生，未來CMOS影像傳感器是否可以改變長久以來被CCD壓抑的宿命，往后技術的發展是重要關鍵。
CCD的市場現狀
CCD更接近于人眼對視覺的工作方式。只不過，人眼的視網膜是由負責光強度感應的桿細胞和色彩感應的錐細胞，分工合作組成視覺感應。CCD經過長達三十多年的發展，大致的形狀和運作方式都已經定型。CCD的組成主要是由一個類似馬賽克的網格、聚光鏡片以及墊于最底下的電子線路矩陣所組成。目前有能力生產CCD的公司分別為：SONY、Philps、Kodak、Matsushita、Fuji和Sharp，大半是日本廠商。我國監控攝像機使用的CCD大多是日本制造的。前段時間日本地震，日本SONY、Sharp等廠商受到影響，我國監控攝像機的價格就隨之上漲。
21世紀，世界進入了信息時代，數字化、計算機化、通訊、電視融為一體的網絡化即將成為現實，讓人們去面對、去學習、去研究。從整個系統來講，CCD攝像機是核心的元件之一，但由于我國CCD攝像機制造技術和CCD傳感器生產線正處于發展和不斷完善的階段，因此，目前我國CCD產業亟待發展，才能適應市場的需求。隨著我國經濟的高速增長，信息產業化進程的加快，CCD攝像機的市場會越來越大，應用的領域將深入到每一個相關的專業領域，將給人們帶來新的概念。
