Energy Star

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
Method of halftone (pseudo-grayscale) image processing which is based on black &
white pixel binarization. It sums the optical density of a pixel and its adjacent pixels,
then relocates black pixels in the order of density to minimize the difference between
scanned and output images. By diffusing the errors onto other pixels, the density data of
adjacent pixels can be binarized. This function suppresses moire patterns of dotted
halftone images such as newspapers, and reproduces its grayscale gradation.
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. They also provide the
certification of low power transmitters and the operation of certified transmitters without
a license.
