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

The example embodiments provides a processing system including an extraction unit that extracts a feature amount of light reflected by a cornea of a person from an image generated by a first imaging apparatus, a comparison unit that specifies an imaging apparatus corresponding to the extracted feature amount of the light based on the extracted feature amount of the light and a reference feature amount indicating a feature of light emitted by each of a plurality of imaging apparatuses at a time of imaging, and a biometric detection unit that performs biometric detection based on a result of whether or not the first imaging apparatus matches the specified imaging apparatus.

Processing system, processing method, and non-transitory storage medium

A living body detection device () includes: an image acquisition unit (), a determination unit () and a detection unit (). The image acquisition unit () acquires a first image in which a subject irradiated by light in a first wavelength range is imaged, and a second image in which the subject irradiated by light in a second wavelength range is imaged, the second wavelength range being different from the first wavelength range. The determination unit () determines whether a relation expressed by luminance of the subject imaged in the first image and luminance of the subject imaged in the second image is a relation exhibited by a living body. The detection unit () detects that the subject is a living body in a case where the determination unit () has determined that it is the relation exhibited by the living body.

Living body detection device, living body detection method, and recording medium

A living body detection device includes: an image acquisition unit, a determination unit and a detection unit. The image acquisition unit acquires a first image in which a subject irradiated by light in a first wavelength range is imaged, and a second image m which the subject irradiated by light in a second wavelength range is imaged, the second wavelength range being different from the first wavelength range. The determination unit determines whether a relation expressed by luminance of the subject imaged in the first image and luminance of the subject imaged in the second image is a relation exhibited by a living body. The detection unit detects that the subject is a living body in a case where the determination unit has determined that it is the relation exhibited by the living body.
