PROBLEM TO BE SOLVED: To provide a new technology which can properly represent an image of relatively lower density.SOLUTION: An image processor comprises: a batch determination unit, which determines a specific batch out of a plurality of batches which correspond to a plurality of kinds of dot lengths that are lengths in a specific direction of a dot region, and which are printed by using a printing execution unit; an exposure pattern determination unit, which determines a plurality of exposure patterns corresponding to each of a plurality of low density values, makes a plurality of exposure patterns serve as patterns with an arrangement of dot regions in a prescribed-sized region, and makes the dot regions arranged in each of the plurality of exposure patterns keep a dot length larger than a dot length corresponding to the specific batch; and a printing image data generation unit, which determines a pixel value of printing image data corresponding to a noted pixel value on the basis of a corresponding exposure pattern when the noted pixel value of target image data is any of the plurality of low density values. |
