The CCD imager is an analog device, whose output is represented in digital form. A CCD device is basically a photon counter, whose voltage signal is directly related to how much light hits the CCD element. After a predetermined amount of time, the digital representation of these voltage levels are clocked out of a shift register, and converted to an image, or whatever the CCD device is being used for.

I think it would be considered an analog device. Even though it has a certain number of pixels, the amount of light that falls onto each pixel is represented in analog form, not digital. I don't follow this very closely and I suppose that there could be a digital CCD. In that case it could be either.
