Characters or image portions are extracted from a background whose color is similar to that of the characters or the image portions. In order to chromatically isolate the characters and the image portions, a threshold value used for binarization is adjusted as the binarization is repeated as necessary or for a predetermined number of times. The adjusted threshold value allows the chromatic isolation of similar colors.
