Claim 0:
1. An image pick-up system comprising:
a plurality of iris image pick-up cameras disposed at mutually different positions in a same field of view;
an overall image pick-up camera configured to perform image pick-up over a wider field of view than the same field of view of the iris image pick-up cameras;
a processor; and
a memory storing instructions executable by the processor to:
using an image from the overall image pick-up camera, reading out an image from the plurality of iris image pick-up cameras, wherein
the plurality of iris image pick-up cameras include:
three or more first iris image pick-up cameras having a focusing point at a predetermined position and configured to perform image pick-up of mutually different regions in a vertical direction, and
two or more second iris image pick-up cameras having a focusing point at a position closer to the first iris image pick-up cameras than the predetermined position, a distance between the focusing point of the first iris image pick-up cameras and the focusing point of the second iris image pick-up cameras being shorter than a distance that a person moves at a predetermined moving speed related to a moving speed of the person during a blink interval time related to a time interval between human blinks and longer than a distance that the person moves at the predetermined moving speed during a predetermined time related to duration of a blink,

each of the two or more of the second iris image pick-up cameras is disposed between two adjacent first iris image pick-up cameras.
