Abstract:
A coloring image generating apparatus includes: an acquiring unit that acquires an image; an edge intensity calculating unit that calculates an edge intensity frequency distribution of the image; a threshold value setting unit that sets a threshold value 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 value and generates a coloring image.
