The object of the present invention is to provide a photographing device,
iris image input device and iris image input method capable of rapidly and
accurately acquiring an iris pattern code of a person to be identified
regardless of the height of the person to be identified. In order to
achieve this object, with an iris image input device of the present
invention, a portable photographing device is connected to a recognition
unit and a monitor. The person to be identified that is to photograph
their iris uses this iris input device in the following manner. The person
to be identified takes the photographing device in one hand, lines up the
photographing device with the eye with the iris to be photographed and
photographs the iris. While doing this, because the iris image of the eye
of the person to be identified photographed by the photographing device is
displayed at a monitor of the iris image input device, the person to be
identified can adjust the position of the photographing device while
looking at the image with their other eye in such a manner that the focal
point of the photographing device lines up with the eye being
photographed. The iris image input device can therefore acquire iris
pattern code for the person to be identified rapidly and accurately.
