Energy Star
ENERGY STAR is an international standard for energy-efficient electronic equipment which was established by the US
Environmental Protection Agency (EPA) in 1992. The standard program has now been adopted by countries around the world.
Error diffusion
High-quality halftone (pseudo-grayscale) image processing based on black-and-white pixel binarization. A pixel's optical
density and that of adjacent pixels are summed, with black pixels relocated in their order of density as they relate to adjacent
pixels. The purpose of this technique is to minimize the average error between scanned and printed densities. Density data for
adjacent pixels is modified by diffusing errors on the objective pixel into several pixels, which are then binarized. This
maintains high grayscale levels and resolution during scanning, while suppressing more patterns by dotted halftone images
such as newspaper photographs.
F
FCC
Acronym for "The Federal Communications Commission", an independent United States government agency which is in
charge of regulating interstate and international communications via radio, television, wire, satellite and cable. The Part 15 of
the FCC regulations mentioned in this manual is designed to prevent harmful interferences on radio communication of radio
receivers and other devices which radiate radio frequency energy, and provides for the certification of radio receivers. It also
provides the certification of low power transmitters and the operation of certificated transmitters without a license.
