Beschreibung
Zusammenfassung:	A sharpness emphasizing method and machine used in a picture reproducing machine such as a color separator, wherein a sharpness emphasizing signal is prepared from a main signal and an unsharp signal, which are obtained by scanning an original picture, in a sharpness emphasizing signal circuit, wherein a corrected sharpness emphasizing signal is selectively produced from the sharpness emphasizing signal depending on the leap of the unsharp signal in a sharpness emphasizing component pickup circuit, and wherein the corrected sharpness emphasizing signal is added to the main signal in a composer circuit, thereby obtaining a picture signal whose sharpness is emphasized in its detail portions.
