ABSTRACT:
The image processing method comprises the steps of: obtaining a distance between an ejection surface of a liquid ejection head in which a plurality of liquid droplet ejection ports are formed, and a recording surface onto which liquid droplets ejected from the liquid droplet ejection ports are deposited; identifying an amount of depositing position displacement of the liquid droplet ejected from each of the liquid droplet ejection ports on the recording surface, according to the distance; and generating droplet ejection arrangement data by correcting image data according to the identified amount of depositing position displacement and performing a halftoning process of the corrected image data.
