Claim 7:
8. An ejection position data generation device 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 processor that detects an edge with respect to at least a part of the image based on processing target data that is image data indicating an image to be printed by the printing apparatus;
an edge correction processor of performing image processing of correcting the edge detected in the edge detection processor on the image; and
an ejection position data generation processor of generating the ejection position data by reflecting a result of the image processing in the edge correction processor; 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;
the edge detection processor detects the edge 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
the edge correction processor performs the image processing of correcting the edge by changing the pixel value of the corresponding pixel to the non-ejection value 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 processor.
