Density processing is performed by
comparing the data in the conversion table
provided for performing edge emphasis, with the
target picture element. (Refer to Fig. 2-510.)
The stages in edge emphasis can be
changed by changing the conversion table and
reproduction ratio (B) of the conversion table.
If the density of the target picture element is
increased fourfold and the density of the other
four points multiplied by -1, the overall density will
remain unchanged.
