Image processing apparatus, image processing method and storage medium

A non-transitory computer readable storage medium storing a program for causing a computer to function as an image processing apparatus, wherein

• the image processing apparatus comprises:
• an image data acquisition unit configured to acquire image data;
• a generation unit configured to generate an ejection pattern of ink droplets from the image data, which are ejected for forming dots from a plurality of nozzles of an image forming apparatus;
• a characteristic acquisition unit configured to acquire an ejection characteristic of ink droplets of the image forming apparatus;
• and
• a pattern change processing unit configured to change the ejection pattern based on the ejection characteristic and the ejection pattern, wherein
• the pattern change processing unit repeatedly performs, in a case where a gap occurs between dots that should be formed so as to contact each other by the image forming apparatus, the ejection pattern change until the gap is eliminated.

An image processing method in an image processing apparatus, the image processing method comprising:

• an image data acquisition step of acquiring image data;
• a generation step of generating an ejection pattern of ink droplets from the image data, which are ejected for forming dots from a plurality of nozzles of an image forming apparatus;
• a characteristic acquisition step of acquiring an ejection characteristic of ink droplets of the image forming apparatus;
• and
• a pattern change processing step of changing the ejection pattern based on the ejection characteristic and the ejection pattern, wherein
• in a case where a gap occurs between dots that should be formed so as to contact each other by the image forming apparatus, the pattern change processing step is performed repeatedly until the gap is eliminated.
