So the video is the whole image that the sensor picks up, upsampled to 640x480?

I'm not sure that 'upsampled to 640x480' is as correct as "converted to NTSC". Depending what camera module you have, you either get an NTSC signal or a PAL signal, and since they are strictly analog they don't really have pixels.

It's a close approximation to NTSC or PAL, anyway. And its modulation is digital enough to make talking about pixels reasonable.

And after all this, the answer to the question itself is what?
