CCDs inspire ADCs to embrace signal processing. (computer-controlled display)(includes related article on analog to digital converters)

EDN, March, 1998 by Schweber, Bill

You need more than just a good A/D converter to effectively interface with a CCD image sensor. Newer converter architectures include signal-processing circuitry that simplifies the task while improving overall performance.

The CCD image sensor is a ubiquitous photon-to-current transducer for applications ranging from relatively slow scanners to high-end, still and full-motion cameras. As with most real-world transducers, under this simple statement is a complex interfacing challenge.

Although you can easily connect your system to a single-element CCD, this simple sensor would not have much practical use except in limited circumstances. As the CCD elements expand into a linear array, your interface challenge becomes more complex, and when you graduate...
