ccd camera to arduino

Hello, I want to ask is it possible to connect CCD camera to Arduino Uno or Mega with composite cable? I have a CCD camera lying around, I tested it with TV it works fine. I want it to be hooked to Arduino and the to pc. I want to see a live video on pc display.

What sort of resolution are you expecting?

I don't thing a 16MHz (or 20MHz) ATMega is anywhere near fast enough for this.

I've done useful commercial image processing on CCIR video on a 20 MHz processor.
It did, however, have a somewhat faster ADC.

I really don’t care about resolution.

I think the ATMega ADC can be operated at CLK/4 or 4MHz on a 16MHz. This gives a sample interval of .25 uS -- fast enough to count out the length of horizontal sync pulses and distinguish the vertical sync from the horizontal for B&W NTSC. But you'd only have about 4 instructions to drive your counting and state machine to time out the actual pixel samples. Going CLK/8 or CLK/16 gives you more processing time, but at CLK/16 or 1Mhz I don't think the timing resolution is fast enough to do the business.
If you managed the frame capture, I suppose you could spit out a 64x48 4-bit deep at a few frames/sec over reasonable serial rates. If you cranked up to a megabit/sec the overhead of loading data to the UART would seriously eat into the time needed to capture the video.
My back-of-envelope guesstimation is that this is not really feasible.
