The present invention comprises the steps of one-dimensionally converting, into a vector, a dot distribution around an attentional pixel in a KxL coordinate (K and L=odd numbers, M=L or K NOTEQUAL L) adjacent to the attentional pixel, specifically, in a 3x3 coordinate, 3x5 (5x3) coordinate or 3x7 (7x3) coordinate on the basis of rasterized data of the coordinate; and then smoothing the image or heightening an image density by correcting a location error of the attentional pixel on the basis of the vector information and the kind of attentional pixel (a dot or a blank). Thus, according to the present invention, the image patterns can be smoothed and the image resolution can be increased in a pseudo state with ease and high precision without complicating a circuit constitution by a simple judgement operation.
