1. An image processing apparatus for inspecting a printed image printed based on image data by using a print head having a plurality of nozzles for discharging ink aligned at first alignment pitches in a first direction and printed on a printing medium conveyed in a second direction intersecting the first direction, the apparatus comprising:
a generating unit configured to generate, based on the image data, judgment image data used for inspection of the printed image, wherein a resolution of an image corresponding to the judgment image data in the first direction is a second resolution which is lower than a first resolution corresponding to the first alignment pitches; and an inspection unit configured to inspect the printed image by comparing read data, which represents an image having a resolution in the first direction equal to the second resolution and is acquired by reading the printed image printed on the printing medium, with the judgment image data. |
