• determining presence or absence of steadiness of the pupil of the subject in the first state based on the first pupil information;
• instructing, upon determining the presence of the steadiness, the subject to be in a second state in which the subject is looking at a position ahead by a second distance shorter than the first distance;
• and
• generating second pupil information that is information relating to the pupil based on an image generated by the photographing the subject in a case where the subject is in the second state.

A non-transitory computer readable storage medium storing a program for causing a computer to perform a process comprising:

• instructing a subject to be in a first state in which the subject is looking at a position ahead by a first distance;

• determining presence or absence of steadiness of the pupil of the subject in the first state based on the first pupil information;
• instructing, upon determining the presence of the steadiness, the subject to be in a second state in which the subject is looking at a position ahead by a second distance shorter than the first distance;
