Patent number: 11188770Abstract: 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.Type: GrantFiled: March 13, 2014Date of Patent: November 30, 2021Assignee: NEC CORPORATIONInventors: Leiming Su, Mamoru Inoue, Kenta Aino, Hiroaki Morita

Publication number: 20210334526Abstract: A living body detection device (1) includes: an image acquisition unit (171), a determination unit (173) and a detection unit (174). The image acquisition unit (171) 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 (173) 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 (174) detects that the subject is a living body in a case where the determination unit (173) has determined that it is the relation exhibited by the living body.Type: ApplicationFiled: July 6, 2021Publication date: October 28, 2021Inventors: Leiming SU, Mamoru INOUE, Kenta AINO, Hiroaki MORITA

Patent number: 9544146Abstract: Interlace noises of the image of an iris included in the image of an eye picked up through an interlaced scheme are corrected precisely within a short time. An image processing apparatus (30) corrects a digital image P based on only low-brightness pixels configuring the image of a pupil included in the digital image P of an eye. Accordingly, interlace noises included in the image of the pupil of the eye and that of the iris can be corrected precisely within a short time. Next, a checking apparatus (50) performs authentication on a subject person based on the image of the iris specified based on the corrected digital image P. Hence, precise authentication is enabled.Type: GrantFiled: January 21, 2010Date of Patent: January 10, 2017Assignee: NEC CORPORATIONInventors: Leiming Su, Yukio Hoshino, Yukio Itakura
