Abstract:
1. An image processing apparatus for printing images on a printing medium by relative scanning between the printing medium and a printing head comprising a plurality of nozzles to eject ink, the apparatus comprising: an acquisition unit configured to acquire both of multi-value image data that is to be printed to a first pixel on the printing medium by using predetermined nozzles, and a first parameter that indicates a degree of concentration of ink in the predetermined nozzles when the predetermined nozzles eject ink to the first pixel; a generation unit configured to generate (i) corrected data by correcting the multi-value image data based on the first parameter and the multi-value image data; and (ii) a second parameter that indicates the degree of concentration of ink in the predetermined nozzles when the predetermined nozzles eject ink to a second pixel that is printed next to the first pixel on the printing medium, based on the first parameter and the corrected data, wherein the generation unit generates the corrected data such that a difference between the corrected data and the multi-value image data in a case where the degree indicated by the first parameter is a first degree is larger than a difference between the corrected data and the multi-value image data in a case where the degree indicated by the first parameter is a second degree which is lower than the first degree.
