1. An authentication device comprising:
a memory storing instructions; and
at least one processor configured to execute the instructions to perform:
detecting an authentication target who is moving toward an exit of a predetermined area;
extracting first biological information of the authentication target from a first image in which an entire body of the authentication target is captured, the first image including the authentication target captured by a first image device;
extracting second biological information of the authentication target from a second image in which an iris of at least one of a right eye and a left eye of the authentication target is captured, the second biological information being different in type from the first biological information, the second image captured by a second image device after the first image is captured by the first image device;
detecting a movement of the authentication target in a direction other than toward the exit of the predetermined area, and stopping extraction of the first image and the second image;
determining whether to authenticate the authentication target using the first biological information and the second biological information; and
adjusting an imaging time when the second image device captures the second image so as to output an authenticate result before the authentication target arrives at the exit of the predetermined area.
