摘要:
Mask size data M and a sharpness enhancement coefficient K are set in accordance with the pixel density of image data S.sub.ij * to be output. The image data S.sub.ij * is determined asS.sub.ij *=S.sub.ij +K.multidot.(S.sub.ij -U.sub.ij)using the mask size data M and the sharpness enhancement coefficient K, wherein the smoothed image data U.sub.ij is defined by the following equation: ##EQU1##
