Abstract:
An image processing apparatus for executing magnification processing for a multivalued image, comprising:a generator, arranged to generate a plurality of binary images corresponding to respective density levels of a multivalued image;an outline extractor, arranged to extract a plurality of sets of outline vectors, from the respective plurality of binary images generated by said generator, each of the plurality of sets of outline vectors representing an outline of each respective plurality of binary images;a magnifier, arranged to magnify the plurality of sets of outline vectors extracted by said outline extractor in accordance with a designated magnification;a smoother, arranged to smooth the plurality of sets of outline vectors magnified by said magnifier;a multivalued image reproducer, arranged to reproduce a multivalued image on the basis of the plurality of sets of outline vectors magnified by said magnifier; andan interpolator, arranged to perform pixel value interpolation for the multivalued image reproduced by said multivalued image reproducer.
