ABSTRACT:
Input image data is stored in a register matrix of 7.times.7 in a successive manner. A pattern detecting section detects a black- or white-pixel connective pattern of the reference pixels of a marked pixel. When the reference pixel pattern is a black-pixel connective pattern of 1:n (n=1, 2, 3, . . . ), an enlarging/smoothing processor section interpolates a part of the enlarged marked pixel with black pixels. When it is a white-pixel connective pattern of 1:n (n=1, 2, 3, . . . ), the enlarging/smoothing processor erases a part of the enlarged marked pixel. As a result, the oblique line can be smoothed. The line that is made thick by the smoothing process can be shaped into a thin line. Thus, a high-quality image can be produced.
