Claim 0:
1. A method for generating ejection position data for generating ejection position data that is data indicating an ejection position where ink is ejected from an inkjet head in a printing apparatus, the method comprising:
an edge detection process of detecting an edge with respect to at least a part of an image based on processing target data that is image data indicating the image to be printed by the printing apparatus;
an edge correction process of performing image processing of correcting the edge detected in the edge detection process on the image; and
an ejection position data generation process of generating the ejection position data by reflecting a result of the image processing in the edge correction process; wherein
the processing target data is data indicating the image configured by pixels associated with the ejection position, and in which a non-ejection value that is a value indicating that ink is not ejected to the corresponding ejection position or an ejection value that is a value other than the non-ejection value is set as a pixel value of each pixel;
in the edge detection process, the edge is detected by detecting a position where a pixel to which the non-ejection value is set and a pixel to which the ejection value is set are adjacent to each other; and
in the edge correction process, the image processing of correcting the edge by changing the pixel value of the corresponding pixel to the non-ejection value is performed for at least a part of the ejection position where ink is ejected from the inkjet head to draw the edge detected in the edge detection process.
