Abstract
Image data of an original image in a prescribed pixel matrix is subjected to edge emphasis. On the other hand, a maximum and a minimum of the image data are detected. Then, values of the image data subjected to edge emphasis are limited between the maximum and the minimum to provide output data. Thus, edge emphasis can be performed without increasing noises even for hand-written characters of low densities.
