ABSTRACT:
An image processing apparatus processes image data which is obtained by reading an halftone dot image. In the image processing apparatus, the image data is separated into the image data corresponding to halftone dots which form the halftone dot image and other image data. On the image data corresponding the halftone dots, the smoothing process is performed, and on the other image data, the edge enhancement is performed. Both of image data are synthesized and outputted. Since only the separated image data corresponding to halftone dots are smoothed out, it is possible to suppress creation of a moiré due to the halftone dot image which is an aggregation of the halftone dots, without influencing the smoothing processing upon the character portion in the vicinity of the halftone dots. On the other hand, since the other image data are edge-enhanced, the character portion, a line and the like show sharp and legible.
