Patent number: 11132536Abstract: 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: GrantFiled: January 3, 2020Date of Patent: September 28, 2021Assignee: NEC CORPORATIONInventors: Leiming Su, Mamoru Inoue, Kenta Aino, Hiroaki Morita

Publication number: 20170017852Abstract: 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: March 13, 2014Publication date: January 19, 2017Applicant: NEC CorporationInventors: Leiming SU, Mamoru INOUE, Kenta AINO, Hiroaki MORITA

Publication number: 20160188266Abstract: An image processing apparatus includes an input unit that receives setting information and a processor. The processor logs in a user based on authentication information received by the input unit, and then sets a setting state of the image processing apparatus for performing an image processing function, according to the setting information received by the input unit after the user is logged in. In response to a logout instruction received by the input unit, the processor provides the setting information to a storage unit accessible to the processor so that the setting information is stored in correspondence with the authentication information in the storage unit, and logs the user out. When the user is logged in again, the processor retrieves the stored setting information corresponding to the authentication information of the user, and sets the setting state of the image processing apparatus according to the retrieved setting information.Type: ApplicationFiled: March 7, 2016Publication date: June 30, 2016Inventor: Hiroaki MORITA

Patent number: 9311033Abstract: An image processing apparatus according to an embodiment includes an authentication unit that authenticates a user and logs in the user when the user is authenticated. An input unit receives an input from the user indicating a setting of a function of the image processing apparatus. A setting management unit causes a storage unit to store setting information corresponding to the setting indicated by the input from the user, while the user is logged in, and to store the setting information when the user logs out. A setting state control unit retrieves the setting information of the user and sets a setting state of the image processing apparatus according to the retrieved setting information when the authentication unit logs in the user.Type: GrantFiled: August 7, 2014Date of Patent: April 12, 2016Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventor: Hiroaki Morita
