Publication number: 20230343129Abstract: 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: ApplicationFiled: June 27, 2023Publication date: October 26, 2023Applicant: NEC CorporationInventors: Leiming SU, Mamoru INOUE, Kenta AINO, Hiroaki MORITA
