Abstract
Even in the case where input image data is binary data, dot arrangement appropriate for a printing apparatus is achieved to output a high quality image that suppresses an adverse influence such as density unevenness, stripes, or granular feeling. For this purpose, after the inputted binary data has been converted to multivalued data having lower resolution, a dot arrangement pattern that preliminarily specifies printing or non-printing for each of print pixels is set with being related to the multivalued data, and thereby new binary data is generated. At this time, the dot arrangement pattern is set to the dot arrangement appropriate for the printing apparatus, and therefore the high quality image that suppresses the adverse influence such as the density unevenness, stripes, or granular feeling can be outputted.
