Abstract:
1. An image processing method for performing a predetermined conversion process with respect to input image data corresponding to each of pixels constituting an image to be formed on a recording medium by first and second dots which can display an identical hue and are different in at least one of a density and a diameter, said method comprising: a first generation step, performed by an image processing unit, for generating independent multi-level data corresponding to the first and second dots on the basis of input image data corresponding to a target pixel; and a second generation step, performed by the image processing unit, for generating data relating to an amount of generation of the first dot with respect to the target pixel on the basis of both of the multi-level data corresponding to the first dot and the multi-level data corresponding to the second dot and for generating data relating to an amount of generation of the second dot with respect to the target pixel on the basis of both of the multi-level data corresponding to the first dot and the multi-level data corresponding to the second dot.
