CCD or CIS: The Technology Decision
This White Paper will explain the two scanning technologies and compare them with respect to quality, usability, price and environmental aspects. The two technologies used in all document scanners are reduction type linear sensors (called CCD) and Contact Image Sensors (CIS). The abbreviation CCD actually stands for Charge Coupled Device, which is the technology used in all image sensors, therefore using CCD as a synonym for reduction type linear sensors is incorrect from a scientific standpoint. But since everyone is using the term CCD for reduction sensors, we will also use it for reduction cameras to avoid confusion
