1. An information processing apparatus comprising:
one or more processors; and
a memory, including instructions thereon, which when executed by the processor cause the information processing apparatus to:
acquire information relating to a geometrical condition in a case where a color chart irradiated with light is captured; and
determine a position at which each of a plurality of color patches is laid out in the color chart based on the geometrical condition,
wherein in the plurality of color patches laid out in the color chart, a color patch having angle dependence and a color patch not having angle dependence are included, and
wherein the color patch having angle dependence is a color patch whose ratio of intensity in a specular reflection direction to intensity in a diffuse reflection direction is higher than that of the color patch not having angle dependence.
