1. An iris capture apparatus comprising:
a processor configured to:
activate a human sensor;
acquire, after the human sensor has detected a user, a first image, the first image depicting an iris of the user, by rotating a rotatable movable mirror, using a motor, of the iris capture apparatus in a first direction;
determine whether the iris is depicted in the first image;
rotate the rotatable movable mirror again, using the motor, in response to the iris not being depicted in the first image, to acquire a second image; and
recognize the user based on an acquired image of the iris,
wherein the processor is configured to capture a third image, the third image depicting iris of the user, from the second image,
wherein the rotatable movable mirror of the iris capture apparatus is rotatable about a first axis, and wherein the processor is configured to rotate the rotatable movable mirror of the iris capture apparatus about the first axis for a predetermined number of times, and
wherein respective parts of two neighboring capturing regions of the iris capture apparatus overlap with each other in a predetermined direction.
