Abstract
In order to correct a thin line to be thin and dense and to prevent the thin line from becoming patchy after binarization of image data without specifying the thin line from image data, an image processing apparatus has the following features. Density peak degrees in four directions are detected by density peak detection filters for four directions, on each pixel. Among the detected density peak degrees of four directions, the maximum density peak degree is used as a degree of thinness of the pixel. For each pixel, the degree of thinness is multiplied by a weight coefficient, and a value obtained by adding the resulting value to the pixel density is used as the new pixel density.
