An image processing apparatus acquires, based on a captured image of an evaluation target object, an optical profile indicating an attribute of an image reflected on a surface of the object. The image processing apparatus also acquires angle information about an angle at each position of the surface of the object relative to an imaging apparatus that captures the image of the object, and corrects the optical profile based on the angle information. The image processing apparatus then acquires an evaluation value indicating a state of the surface of the object based on the corrected optical profile.
