CCD and CMOS sensor

[raprap]

can anybody tell me which is better whats the difference between this two?

There are some differences, most of them minor for most purposes, and the differences are mostly handled adequately in the camera.

There are plenty of more important differences between cameras than the process used to manufacture the image seonsor. I suggest you narrow down your choice of camera by what you want to shoot, how you want to shoot it, and how much you want to spend, not the type of image sensor a particular camera might have.

Most experts agree and extensive research has shown that the CCD sensor is far superior to the newer CMOS sensor. The CCD sensor has much better image quality (better resolution, less noise, more dynamic range and more saturated and vibrant color contrast) However, if picture quality is not that important to you, the new CMOS sensor is absolutly outstanding for low light picture taking....must better than the CCD sensor. Another place where the CMOS sensor beats the CCD sensor is that it uses less power...a lot less. The camera manufactures like it as well because it is much cheaper to manufacture. The CMOS sensor is rather new as compared to the CCD sensor and the technology is constantly evolving, so don't be surprised that someday it will be far superior to the CCD sensor in all respects.

Instead of asking which technology is better, it makes more sense to ask which particular chip is best for a given spec. You can find such evaluations on DXO (http://www.dxomark.com/) I'm not sure I would know what to make of the notion that CCD is better than CMOS, but this particular CMOS chip outperforms any existing CCD chip in terms of noise or dynamic range or what-have-you. Since the chips that exist have been evaluated for various performance characteristics, why not just examine them. Next year's crop of chips may have different performance characteristics. But, in the words of Anselm, "Existence is greater than nonexistence."

To add to the above but to put into other terms...

It's like motor cars - some use diesel fuel, others use gasoline
Both end up doing the same job but with differing but similar technologies
... and like anything else, each has its followers and its detractors

Camera sensors are the same

Actually, the difference between CCD and CMOS sensors is slight, and how they are implimented in each model camera has more to do with image quality than the type of technology used to create the sensor.

Any time you try to make generalizations, even if your right, you're still wrong as much as 49% of the time.

[TCav]

That's why I almost never make generalizations.

[VTphotog]

In general, you mean.

A good comparison between a CCD sensor and a CMOS sensor as far as "image quality" goes is to simply look back at all the reviews comparing the old Fuji S200 EXR with the newer Fuji HS-10 EXR and HS-20 EXR models. The old Fuji S200 EXR used what Fuji called the Super CCD sensor. The newer Fuji HS-10 and HS-20 models came with CMOS sensors. In every review when comparing "image quality only", the experts all agreed that the image quality was far superior with the old Fuji S200 with it's CCD sensor as compared with the other two newer models that used CMOS sensors.
