ABSTRACT:
The multi-tone image data is converted to a plural sets of binary image data with a plurality of density levels as threshold values. Contraction and expansion are sequentially executed on the plural sets of binary image data to correct a contour of each binary image. The plural sets of the processed binary image data are re-converted to multi-tone image data which represents a multi-tone image having a corrected contour.
