The present invention provides a technology that acquires a high resolution iris image more quickly than before. An iris capture apparatus according to one example embodiment of the present invention includes a rotatable movable mirror; a control unit that controls rotation of the movable mirror; a capture unit that captures different regions of a face of a user via the movable mirror and outputs a group of images every time the control unit rotates the movable mirror by a predetermined angle; and an iris image acquisition unit that acquires an image of an iris of the user from the group of images.

Iris capture apparatus, iris capture method, and storage medium

A light source () of a disguising mask detecting device () emits light at a person who is a subject. A camera () acquires images in multiple different wavelength ranges of reflected light of the light emitted at the person. A face detector () detects a face region of the person from the images acquired by the camera (). A determiner () determines that the person is wearing a disguising mask when luminances of the face region in the images satisfy specific relations different from relations exhibited by skin.

Detecting device, detecting method, and recording medium

An example embodiment includes: a determination unit that, based on an image including an eye of a recognition subject, determines whether or not a colored contact lens is worn; and a matching unit that, when it is determined by the determination unit that the colored contact lens is worn, performs matching of the iris by using a feature amount extracted from a region excluding a predetermined range including an outer circumference of the iris out of a region of the iris included in the image.

Iris recognition system, iris recognition method, and storage medium

Provided is an information processing system including: a comparison information acquisition unit that acquires comparison information regarding iris comparison generated based on an iris image including an iris of a recognition subject; and a display image generation unit that generates a display image including an image indicating a content of the comparison information in association with positions in the iris.

Information processing system, information processing method, and storage medium

Provided is a colored contact lens having: a lens; and a colored region formed in the lens, at least a part of the colored region is arranged at a position overlapping an iris of a wearer when the colored contact lens is worn, and the colored region has infrared transparency.

Colored contact lens, manufacturing method of colored contact lens, and iris recognition system

An image processing device outputs, by using a result of machine learning, an image including three or more gradations and indicating a central line in response to an input of a fingerprint image, the machine learning being performed by using data including at least a fingerprint image, central line information indicating a central line in the fingerprint image, and zone information indicating a zone that is a portion of the fingerprint image which is effective for fingerprint collation, and generates a binary central line image based on the output image.
