  • Publication number: 20250095404
    Abstract: 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.

  • Patent number: 12183112
    Abstract: A light source (11) of a disguising mask detecting device (1) emits light at a person who is a subject. A camera (12) acquires images in multiple different wavelength ranges of reflected light of the light emitted at the person. A face detector (172) detects a face region of the person from the images acquired by the camera (12). A determiner (173) 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.

  • Patent number: 12131585
    Abstract: 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.
