<P>PROBLEM TO BE SOLVED: To generate a good coloring image based on an image. <P>SOLUTION: A coloring image generating apparatus includes: an acquisition unit that obtains the image; an edge intensity calculating unit that calculates an edge intensity frequency distribution of the image; a threshold setting unit that sets a threshold for dividing a coloring image into a contour portion and a blank portion according to distribution characteristics of the edge intensity frequency distribution; and a generating unit that discriminates the contour portion from the blank portion in the image on the basis of the threshold and generates a coloring image. <P>COPYRIGHT: (C)2010,JPO&INPIT |
