The method includes: performing a halftone process with a dither matrix on image data that represents a tone value of each pixel making up an original image to determine a state of dot formation at each of print pixels of a print image that is to be formed on the printing medium, and generating dot data that represents the determined state of dot formation; and generating a print image by mutually combining each of dot groups that are formed at each of a plurality of pixel groups in a common print region according to the dot data, the plurality of pixel groups being assumed to have different physical conditions with respect to the dot formation. The dither matrix stores each threshold value such that a number of dots to be allocated to each of the plurality of dot groups is determined according to a dot formation order of each of the plurality of dot groups in the common print region in the halftone process.

摘要： An image is divided into first a second regions on the basis of inputted image data, and a comparison is made between the gradation values of pixels in the first region and threshold values corresponding to the pixels of the first region of a dither mask. The results of the comparison are referenced to determine whether or not dots are formed in the pixels of the first region. Errors are calculated based on the results of determining the first boundary pixels, which are in the first region near the boundary between the first region second regions. Some of the errors are distributed as diffusion errors to pixels in the second region near the boundary. The diffusion errors distributed from the first boundary pixels are added, and it is determined whether or not dots are formed by the error diffusion method in the pixels of the second region.
