ABSTRACT:
An image processing apparatus is arranged to set a center pixel in coloring each area within a diagram image prepared by detecting an edge in an original image, to obtain the shortest of distances from the center pixel to the edge in eight directions, and to color the inside of a coloring circle whose radius is the shortest distance. The arrangement effectively prevents a colored area form excessively bulging out beyond the edge even when the edge includes a vague part, because the area of coloring is limited to the inside of the coloring circle. Therefore, the possibility of having an image prepared in any undesirable manner can be minimized. Further, a plurality of pixels selected at uniform intervals within the diagram image are arranged to be used as the center pixel for coloring.
