In an image processing apparatus, a first recognition section recognizes a black character portion and a color character portion in CMY color signals input from a color conversion section, and outputs a recognition result to a third recognition section. A second recognition section recognizes a low-density region (including a white portion) and a narrow region surrounded by the low-density region in the CMY color signals input from the color conversion section as a low-density region, and outputs a recognition result to the third recognition section. The third recognition section synthesizes the recognition result from the first recognition section and the recognition result from the second recognition section, and delivers a resultant recognition signal to a filtering section, a black signal generating section and a tone processing section. The filtering section, black signal generating section and tone processing section execute processes in accordance with the recognition signal from the third recognition section.
