Abstract
A smoothing method and a smoothing apparatus for smoothing a contour of a dot pattern of a character extract a contour of a dot pattern of a character to be smoothened, smoothen the contour of the dot pattern, and carry out a rectilinear interpolation and a corner rounding process on a smoothened contour which is obtained after the contour is smoothened. The process of smoothing the contour includes a step of extracting corner points of the contour of the dot pattern, and a step of determining each position of curve points of each object corner point based on the direction and distance of each object corner point from other corner points before and after the object corner point for each of the extracted corner points, where the curve points constitute the smoothened contour of the character.
