    Abstract: The disclosure is detecting an authentication target who is moving in a predetermined direction in a video; inputting a first image in which an entire body of the target; calculating characteristic information from an image of the entire body in the first image, comparing the calculated characteristic information with characteristic information of the entire body stored in first memory that stores characteristic information of entire bodies of targets, and extracting candidate information of the targets from the first memory based on a first authentication result; inputting a second image in which an iris of the target; and comparing characteristic information of irises stored in second memory that stores the characteristic information of the irises of targets with characteristic information of an iris from the second image, calculating a verification score, executing second authentication on the target in the second image based on the verification score, and outputting an authentication result.

    Abstract: An illumination device emits light toward a moving subject. A controller controls light emitted from the illumination device so that the amount of light applied to the subject is adjusted to a specific amount or smaller. For example, when the illumination device emits light in a pulsed manner, the controller may control the amount of light applied to the subject by controlling at least one of the pulse width and the pulse intensity of the light. The controller may, for example, control the light emitted from the illumination device according to the distance between the illumination device and the subject.

    Abstract: A biometric authentication system (10) comprises a first imaging unit (11) that images a first image including a living body; a detecting unit (115) that detects a position of the living body in the first image; a second imaging unit (120) that images a second image including an authentication portion of the living body, based on the position of the living body in the first image; a calculating unit (140) that calculates an error between the first imaging unit and the second imaging unit based on the position of the living body in the first image and a position of the authentication portion in the second image; and an adjusting unit (150) that adjusts a set value relating to the second imaging unit, based on the error.

    Abstract: Provided is a gate system arranged between a first region and a second region, including a guide that defines a movement path of a user from the first region to the second region and an imaging device that photographs the user to acquire an image used for biometric authentication. The movement path includes a first portion in which the user is photographed and a second portion through which the user passes after being photographed. The first portion extends from the first region toward the imaging device in a first direction that is parallel to an optical axis of the imaging device. The second portion extends from an end of the first portion in a second direction that is not parallel to the first direction.
