  • Patent number: 11983961
    Abstract: Iris image pick-up devices perform image pick-up of an iris of a moving subject. A guiding device guides the subject. A controller predicts a period in which the subject will blink next. Further, the controller predicts a period in which the subject will pass through the focusing point of the iris image pick-up devices. The controller controls the guiding device such that the subject does not blink at the focusing point in the case where the period in which the subject will blink next overlaps with the period in which the subject will pass through the focusing point.
