Abstract:
An image is generated by performing area coverage modulation to express a halftone color according to a gross area of dots displayed in a pixel of the image. The image is generated in such a manner that the halftone color is expressed with a selected one of dither patterns corresponding to respective predetermined densities, each of the densities being determined by the gross area of dots calculated in view of shapes of the dots.
