1. An image processing apparatus comprising:
a printing unit configured to print an image in a region on a printing medium based on input image data by using a printing
head having an array of nozzles for ejecting ink;

an obtaining unit configured to obtain information regarding a state of ink ejected from the printing head to the region at
a timing when the image based on the input image data is printed by the printing unit;

a determination unit configured to determine an inspection item on which a read image is obtained by reading the image printed
by the printing unit based on the input image data by a reading unit to be inspected from a plurality of inspection items
based on the information obtained by the obtaining unit wherein a kind of the determined inspection item varies according
to the state indicated by the obtained information; and

an inspection unit configured to inspect the read image by performing, on image data of the read image, image processing corresponding
to the inspection item determined by the determination unit.
