1. An iris capture apparatus comprising:
a processor configured to:
activate a human sensor; and
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 of the iris capture apparatus repeatedly by a predetermined angle;
capturing different regions of a face of the user and outputting a group of images when the rotatable movable mirror is rotated by the predetermined angle, wherein:
capturing the different regions of the face of the user comprises capturing a first capturing region when the rotatable movable mirror is at a first state, the first capturing region including the face of the user;
rotating the rotatable movable mirror of the iris capture apparatus comprises rotating the rotatable movable mirror by the predetermined angle from the first state; and
capturing the different regions of the face of the user further comprises capturing a second capturing region, wherein the second capturing region is offset a predetermined distance in the vertical direction from the first capturing region; and
identifying an image depicting the iris of the user from the group of images as the first image.
