发明名称 Verfahren und Anordnung zum Erzeugen eines Konturvektors und zur Bildvergrösserung/-verkleinerung
摘要 When an image is input, that input image is separated into a halftone region, such as a photograph, and a binary region, such as a character/line. Contour vector data along an edge of the separated binary image region is extracted. The contour vector is smoothed and isolated pixels in the binary region are removed. Regarding the binary image region, when the input image is to be enlarged or reduced and then output, individual coordinates in the extracted contour vector data are enlarged or reduced to reproduce the binary image. <IMAGE>
