摘要

Apparatus for reproducing a scanned picture with sharpness emphasized. A scanner is provided for scanning a picture to be reproduced in two directions perpendicular to one another and for generating and recording signals representing the scanned picture. There is a sharpness emphasizing device for summing and averaging a plurality of picture element signals aligned in one of the scanning directions in the vicinity of a scanning point in the picture being scanned and recorded to generate values and then summing and averaging a plurality of the resulting summed and averages picture signals aligned in the other scanning direction in the vicinity of said scanning point to generate further values and then producing a recording signal equal to S+k(S-U), where k is a constant chosen to enhance a particular characteristic of the scanned picture, S is the sharp signal component at said scanning point and U is a generated unsharp signal. Finally, there is a device for receiving the recording signal and for employing it to reproduce the scanned picture.
