1. An imaging system comprising:
a memory storing instructions, and
a processor configured to execute the instructions stored in the memory to:
control, in such a way as to fix a focal position in a predetermined position, an iris imaging unit capturing an image focusing on an iris of a target person;
authenticate the target person, based on an iris image of the target person being captured by the controlled iris imaging unit;
control the iris imaging unit in such a way as to scan a focal position in a predetermined range, in order to re-authenticate the target person when authentication of the target person fails;
control in such a way as to fix the focal position when the target person is authenticated in a first authentication mode; and
perform control in such a way as to scan the focal position when the target person is authenticated in a second authentication mode, wherein
the first authentication mode is an authentication mode of authenticating the target person while moving, and
the second authentication mode is an authentication mode of authenticating the target person while stopping.
