Abstract

An apparatus for producing a contour line pattern image from an original image such as a character or the like recorded in binary format in a memory couples image element points equidistantly isolated from edges of the original image and thereby forms a contour line pattern curve. The coupling of the equidistant points and the formation of the contour line pattern curve in the contour line pattern image are repeatedly carried out. Smudged areas of the contour line pattern image are detected and eliminated and missing portions of the contour line pattern image are regenerated.
