1. An imaging system comprising:
iris an imaging device configured to photograph an iris of a subject;
a first illuminator configured to apply light to the subject;
a second illuminator configured to apply light to the subject in such a manner that an angle between an optical axis of the light emitted from the second illuminator and an optical axis of the iris imaging device is larger than an angle between an optical axis of the light emitted from the first illuminator and the optical axis of the iris imaging device;
a controller configured to determine whether or not the subject is wearing glasses, and control an operation performed by the first and second illuminators based on a result of the determination; and
a guiding device configured to guide the subject, wherein
the controller operates the first illuminator so that the light is emitted from the first illuminator when the subject has been determined to not be wearing glasses,
the controller operates the second illuminator so that the light is emitted from the second illuminator when the subject is determined to be wearing glasses,
the controller operates the guiding device so that the subject is guided to move to an overlapping range between an irradiation range of the first illuminator and an imaging range of the iris imaging device when the subject is determined to not be wearing glasses, and
the controller operates the guiding device so that the subject is guided to move to an overlapping range between an irradiation range of the second illuminator and the imaging range of the iris imaging device when the subject is determined to be wearing glasses.
