菜鸟的CCD问题。

jhtaiyang

初来咋到，对CCD器件很不熟悉。我想问问如何确定CCD的摄像时能拍摄到的面积是多少？问的很不专业，还请各位高手耐心解答。小女子不胜感激！

怎么没有人回答？是不是问题太简单了，高手们都不屑一顾啊！

这个问题和CCD无关。而是取决于镜头等设备和工作距离等。简单的说，好比照相机，即可以成像在无穷远处（拍摄的面积很大），也可以成像在很近的地方（面积较小）。不知道是不是你问的？

well.. it depends what area you are talking about, the object or the ccd chip?

first , for the first case, Lengxue is right , you can try to measure the object or you can calibrate your lens before you take shot.

for the second case, that's really a problem. for normal ccd camera, the effective area ( the area which was used for imaging) is a bit smaller than the full area of the CCD chip, You may check the specification of your camera, there may be some parameters for this. or you can check with the manufacturor.

应该可以根据摄像头和焦距有关
