Re: image sensor

has anyone used an image sensor particularly the CDD one?
What is the output of that image sensor, digital or analog, tnx

Added after 39 seconds:

CCD sensor i mean, not CDD
 

Re: image sensor

Try to imagine a 2-D array of thousands or millions of tiny solar cells, each of which transforms the light from one small portion of the image into electrons.
After that the next step is to read the value (accumulated charge) of each cell in the image. The charge is then transported across the chip and read at one corner of the array. An analog-to-digital converter turns each pixel's value into a digital value. And because the A/D converter is always associate with that array, you can easily say, that the output from a CCD sensor is digital ..
