    摘要: An image processing apparatus includes an input section and a binarizing section. The input section inputs multilevel image data. The binarizing section binarizes multilevel image data to generate output image data representing halftone dots each having a hollow-structure. The binarizing section enlarges the halftone dots in a predetermined direction preferentially in accordance with the input multilevel image data.

    摘要: An image processing method generates a halftone-dot image by forming a halftone dot, which is represented by a set of one or plural output dots and corresponds to an intensity of an input image signal, while making a part of the dots constituting the halftone dot to be an actual non-output dot so as to reduce an amount of a coloring material of the halftone-dot portion. When the intensity of the image signal exceeds a predetermined value and is in a predetermined range, while maintaining contour dots, which are output dots contribute to formation of a contour of the halftone dot, to be the output dot, the image processing method makes a part of dots inside the contour dots to be the actual non-output dot.
