How to learn to the implementation a sensor?

Is there any document of the introduction of the implementation of CCD/CMOS sensor?thanks for help..

Start with this one:

Why sensor is difficult to implement for high image quality?Should I learn from analog or from image processing?Thanks.

Basically it is the number of pixels that determine resolution.
More on this subject you can find through GOOGLE; type: CCD+resolution

Example: http://www.camerafever.com/exp001_CCD.html

mmm....
The quality depends on the resolution..,but why is it difficult to implement?
The key is image processing or analog/ADC? sorry..I am a newer for this topics.

The answer is this: phisical size of single pixel.
If you are talking about mega-pixels and you want to fit them within 1/4square inch structure, what size is left?
Pretty common resolution is around 330 TV lines. But now you can buy CCD with resolution close to 750 lines: main difference - 2-3 times more pixels, and you pay 10x mor for the second.

By the way,why sensor need to use isp to correct the image?By you words, isp isn't very important,or I miss your words?.

Images of a scene can be distorted by aberrations in a lens system that warp or otherwise distort the images before they are digitized by an image sensor. Alternatively, the images formed by a flat panel or other electronically addressable display can be distorted when they are cast upon a screen when the image source is not parallel or at right angles to the screen.

And terefore digital signal processing is required but it has not much to do with number of pixels and resolution..

let me sum up some basic rules:

- more pixel (higher resolution) you have, smaller are the pixels or bigger is the sensor...
and
- smaller are the pixel size, worst is the image ( smaller light to current/voltage conversion ratio : SNR !)
- bigger is the sensor, more expensive is the system (smaller yield, large lenses...)

so, basically, the analog compromises will rule out the highest quality you can reach !

Typically, the ADC is not an issue as state-of-the-art ADCs can cope with SNR/data rate of best sensors.

Anyway, signal processing is always needed with any image sensors, whatever its "quality" !
Raw images are not "ready" for display... you have at least to perform color reconstruction and oftenly pattern correction (pixel pattern, column/row pattern) and bad pixels interpolation.
Then, other processing are oftenly needed (histogram enhancement, color enhancement & geometric corrections...)
