ABSTRACT:
An apparatus processes two-tone image data so as to magnify a relevant image and smooth a boundary line between a zone consisting of first-tone pixels of two-tone pixels constituting the relevant image and a zone consisting of second-tone pixels of the two-tone pixels. The apparatus is characterized in that the apparatus comprises a unit which, for each two-tone pixel of the two-tone pixels, determines a template pattern, from among a plurality of template patterns, as matching a pixel arrangement comprising pixels located around the each two-tone pixel; and a unit for converting the each two-tone pixel into either single multiple-tone pixel of plurality of multiple-tone pixels, the unit using a result of the determination performed by the unit for the converting.
