摘要： 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.

摘要： An aperture plate for use in the exposure head of a picture scanning reproducer which constructs an image by exposure of a film attached to a rotating drum in scanning mode, the aperture of which plate has a shape incorporating parallel lines and end portions consisting of twin lines opening up away from a cusp, which in some embodiments may be exponential curves, whereby overlap effects in the constructed image are substantially eliminated.
