Can i use a phone camera as USB or composite AV?

Ok i missed the Math question first time so now have to type this again! Is it possible to acquire a video signal from the CCD unit from a mobile phone (in this case a 5MP samsung D900) when removed from the phone, i.e, with separate power supply and either composite video or USB connection? I have removed the unit from the camera complete with it's ribbon cable and would appreciate any advice/wiring diagrams/don't bother you're mad-type comments from the learned readers herewith. I am attempting to construct a mobile eye-tracking device and have tried using commercially-available miniature CCD & CMOS units, but cannot get the resolution required from these, so thought perhaps this may be a solution. Many thanks

I don't see why not if you can figure out the pin-outs and the signal from those pins. To me, that would be the hard part.

You already have experience, so you'd probably think I'm just saying the obvious . . . The CCD itself won't get you an image. You'll need the lens as well. It might be on the phone, or glued onto the CCD.

Thanks Chieh,

Obvious but easily forgotten, the lens is part of the unit itself so not an issue here. My main concern is that for most CCD devices i've encountered up to now, there are four cables, power + & -, video ground and signal. There are at least six cables/conductors from this device, and i am concerned that they may be to do with autofocus etc, but have been unable to find ANY literature/wiring diagrams for this type of device. As the phone itself is dead, having descended four floors without stairs or a parachute, (but the camera still works!) i don't have much to lose :-), but it's always worth asking if anyone else has done the hard part for you already... Thanks again for your post, i will keep this thread going til i find a solution, or win the lottery and retire to the Seychelles!

Haha. Thanks for the heads-up. Looking forward to reading your adventure here.

I'm sure whatever you discover will be helpful to folks all around. I, among many, have a number of old camera phones sitting around, and sure wish we can do something more with them; the phone companies aren't taking them back.
