Iris capture apparatus, iris capture method, and storage medium

A method of capturing an iris executed by an apparatus that includes a camera capturing a person, a motion sensor detecting a person being present within a region where the camera can capture an iris, and a light source emitting infrared light to a person, the method comprising:

• causing the camera to repeatedly capture an image including a first capturing region and a second capturing region to cause the camera to capture a first facial image of the person, the second capturing region being a region shifted from the first capturing region in a vertical direction by a predetermined length;
• determining whether an iris image of the person usable for iris recognition has been obtained from the first facial image;
• when determined that the iris image has not been obtained, causing the camera to perform the repeatedly capturing an image including the first and second capturing regions again to cause the camera to capture a second facial image of the person;
• determining whether the iris image of the person has been obtained from the second facial image;
• and
• when determined that the second facial image includes the iris image, executing the iris recognition.

A non-transitory computer readable storage medium storing a program that causes a computer to control an apparatus that includes a camera capturing a person, a motion sensor detecting a person being present within a region where the camera can capture an iris, and a light source emitting infrared light to a person, the computer controlling the apparatus to:

• cause the camera to repeatedly capture an image including a first capturing region and a second capturing region to cause the camera to capture a first facial image of the person, the second capturing region being a region shifted from the first capturing region in a vertical direction by a predetermined length;
• determine whether an iris image of the person usable for iris recognition has been obtained from the first facial image;
• when determined that the iris image has not been obtained, cause the camera to perform the repeatedly capturing an image including the first and second capturing regions again to cause the camera to capture a second facial image of the person;
• determine whether the iris image of the person has been obtained from the second facial image;
• and
• when determined that the second facial image includes the iris image, execute the iris recognition.
