Digitization Effects
•The “diameter” d of a pixel determines the highest frequency representable in an image
•
•
•
•Real scenes may contain higher frequencies resulting in aliasing of the signal.
•
•In practice, this effect is often dominated by other digitization artifacts.
•
•One problem in particular is differing sampling rates between digitizer and camera readout of a row.
