Abstract: An image processing apparatus in an embodiment is an image processing apparatus for forming structures on a print medium, the structures being configured to express such a characteristic that sparkle points change in position with change in angle of observation. The image processing apparatus in this embodiment includes a generation unit configured to generate arrangement data based on information on a characteristic of sparkle points, the arrangement data specifying arrangement of the structures of two or more types that are capable of being formed on the print medium and at least include one or more first structure associated with a first inclination angle and one or more second structures associated with a second inclination angle different from the first inclination angle.
