ABSTRACT:
An image processing apparatus includes a binarizing unit, a determining unit, a counting unit, and a correcting unit. The binarizing unit binarizes image data based on density of the image data. The determining unit determines a pixel with high density as a character pixel and a pixel with low density as a non-character pixel in the binarized image data. The counting unit counts the number of a sequence of character pixels in a scanning direction. The correcting unit corrects, when the number of the sequence of the character pixels exceeds a threshold value, the character pixels to non-character pixels.
