1. An information processing device used in an image capturing device illuminating an object and capturing reflected light from the object as a reflection image, the information processing device comprising:
a memory storing instructions; and
at least one processor configured to execute the instructions to perform:
on a basis of a measurement result of unevenness of a surface of the object, generating an inclination distribution representing a relationship between inclination angles at a plurality of points on the surface of the object and respective frequencies of the inclination angles, and calculating two types of inclination statistic values including a first inclination statistic value and a second inclination statistic value, the first inclination statistic value being an angle that halves an area of the inclination distribution, the second inclination statistic value being an angle extracted from a right bottom portion of the inclination distribution; and
determining an irradiation angle range for irradiating the object, on a basis of the calculated two types of inclination statistic values.
