数码相机CCD：原理、分类及优缺点英文双语对照

数码相机CCD工作原理

对于数码相机来说，CCD（电荷耦合器件）是一种重要的影像感应器件。它通过将光线转换为电信号的方式，实现捕获图像的功能。CCD工作原理主要基于光电效应，当光线照射到CCD上时，产生电荷，并通过信号放大电路和模数转换电路输出为数字图像。

数码相机CCD分类

根据制作工艺和结构，数码相机的CCD主要分为两种：前照式CCD和后照式CCD。前照式CCD是指光线先穿过透镜透过感光面照射到CCD上，而后照式CCD则是光线先穿过CCD后再通过透镜透射到CCD上。

数码相机CCD优缺点

数码相机CCD的优点是感光元件数量多，灵敏度高，并且适用于成像画质较高的设备。然而，CCD也存在一些缺点，比如功耗高、成本昂贵以及成像速度相对较慢。

通过了解数码相机CCD的工作原理、分类以及优缺点，可以更好地选择适合自己需求的数码相机，同时也有助于更好地理解数码相机的成像原理。

Principle of job of digital camera CCD

To digital camera, CCD (charge coupling parts of an apparatus) it is a kind of important video induction parts of an apparatus. It adopts the way that changes the light the signal that it is report, implementation captures the function of image. CCD job principle basically is based on photoemission, when radial illuminate arrives on CCD, generation charge, magnify through signal circuit and modulus change-over circuit output picture of amount to word.

Digital camera CCD is classified

The basis makes craft and structure, the CCD main component of digital camera is two kinds: Type CCD is illuminated after be being mixed according to type CCD before. Type CCD is being illuminated before is to show the light crosses lens to arrive through sensitive face illuminate on CCD first, illuminating type CCD after that is transmission of lens of the repass after the light crosses CCD first arrives on CCD.

Defect of actor of digital camera CCD

The advantage of digital camera CCD is sensitive component amount much, sensitivity is tall, and apply to become qualitative like the picture higher equipment. However, CCD also is put in a few defect, power comsumption is for instance tall, cost is high and into opposite like speed slower.

The working principle that adopts CCD of knowledge number camera, classification and actor defect, can choose to suit the digital camera of own demand better, also conduce to what understand digital camera better becoming at the same time like the principle.
