<p>PROBLEM TO BE SOLVED: To reduce resources required for a dither mask even when using the dither mask corresponding to a non-injecting nozzle, and to prevent a gradation from being reduced by dither processing even if the non-injecting nozzle is generated.SOLUTION: An image processing section includes: a storage part for storing a predetermined dither mask; a defective nozzle detection part for detecting a defective nozzle; and an interpolation processing part which identifies a mask position corresponding to a position of the detected defective mask from among mask positions included in the dither mask, and changes a threshold value of a predetermined mask position included in the dither mask so as to turn on a dot at the predetermined mask position in the case where a dot at the identified mask position is ON.</p> |
