Abstract:
An image processing apparatus includes an acquisition unit, a determination unit, and a thinning unit. The acquisition unit may acquire color information concerning color of an image having an attribute of at least one of character or line drawing. The determination unit may determine a thinning ratio for thinning data of non-edge portions of the image according to the color information acquired by the acquisition unit. The thinning unit may thin data of the non-edge portions according to the thinning ratio determined by the determination unit. The thinning ratio determined by the determination unit when the color information indicates a color other than black is lower than the thinning ratio determined when the color information indicates black.
