Kell Factor
The Kell factor, named after RCA engineer Raymond D. Kell, is a parameter used to limit the bandwidth of a sampled image signal to avoid the appearance of beat frequency patterns when displaying the image in a discrete display device, usually taken to be 0.7. The number was first measured in 1934 by Raymond D. Kell and his associates as 0.64 but has suffered several revisions given that it is based on image perception, hence subjective, and is not independent of the type of display. It was later revised to 0.85 but can go higher than 0.9, when fixed pixel scanning (e.g., charge-coupled device, CCD or Active pixel sensor, CMOS) and fixed pixel displays (e.g., liquid crystal display, LCD or plasma display, plasma) are used, or as low as 0.7 for electron gun scanning. From a different perspective, the Kell factor defines the effective image resolution, resolution of a discrete display device since the full resolution cannot be used without viewing experience degradation.
