Patent number: 11790716Abstract: A face authentication apparatus includes a face image acquisition unit, a collation unit, a time measurement unit, and a threshold change unit. The face image acquisition unit acquires a face image of an authentication target. The collation unit performs face authentication on the face image of the authentication target on the basis of a threshold. The time measurement unit measures the elapsed time from the time of starting operation of the face authentication apparatus. The threshold change unit restricts changing of the threshold to a value larger than a value determined depending on the measured elapsed time.Type: GrantFiled: February 16, 2022Date of Patent: October 17, 2023Assignee: NEC CORPORATIONInventors: Taketo Kochi, Kenji Saito
