    The CCD element collects image information upon 'exposure'. This information is then shuffled into a very fast ADC, then off to memory.

    Modern digital cameras make the most of integration. Single or multiple piece chipsets will pack a lot of functionality into very small footprints. In a single camera chip you may expect to find the ADC, DSP filtering, Jpeg encoders/decoders, memory controller, CCD drivers, focus drives, etc, etc. And thats just the hardware.

    In many cases you'll find a secondary microcontroller that handles interfaces such as keypadding, power management, and the like.
