Apparatus for generating image data, method, and medium

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.

An image processing apparatus is used for processing of reproducing a target object by applying color onto a structure formed based on a concavo-convex signal indicating a shape of the target object. The image processing apparatus determines, based on concavo-convex data, color data, and color reproducibility, a correction area which is an area in which color reproduction represented by the color data is decreased according to the shape represented by the concavo-convex data. The image processing apparatus corrects the concavo-convex data by smoothing the concavo-convex signal corresponding to the determined correction area.

Provided is an image processing apparatus capable of adjusting a color of an image of an observation target depending on differences between viewing angles. The image processing apparatus obtains a viewing angle of a first observation target and a viewing angle of a second observation target, and then corrects the color of each observation target by using the obtained viewing angles of the first and second observation targets.
