Abstract

An image processing apparatus that monochromatizes a gray pixel included in bitmap image data into black pixel includes: a detection unit (S202) configured to detect, in the case where a pixel of interest in the image data is a pixel constituting an edge, a pixel that exists in the vicinity of the pixel of interest and whose color is different from that of the pixel of interest; and a determination unit (S207) configured to determine a ratio of the processing to monochromatize into black for the pixel of interest that is a pixel constituting the edge based on the distance from the detected different color pixel.
