ABSTRACT:
The contour vectors of an image are stored in a small storage capacity, and are enlarged/reduced in correspondence with a desired variable-magnification factor to be faithful to an input image. For this purpose, when a binary image is input from a binary image input unit (11), a contour vector extraction unit extracts contour vectors, and detects the positions of isolated points. The contour vectors are enlarged/reduced by a vector variable-magnification/smoothing unit (13), and a binary image is reproduced by a binary image reproduction unit (15). On the other hand, each of the isolated points is subjected to variable-magnification processing by an isolated point variable-magnification processing unit (14), so that its position is converted into a position corresponding to the variable-magnification factor, and points corresponding in number to the variable-magnification factor form the isolated point. Thus, the storage capacity of the isolated points can be reduced, and the isolated points are subjected to variable-magnification processing at an appropriate variable-magnification factor corresponding to the desired variable-magnification factor.
