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.

Abstract: An imaging system includes: a first control unit that controls an imaging unit to capture a first image of a subject at a first pixel density; a detection unit that detects an eye position of the subject from the first image; a setting unit that sets a peripheral area around eyes of the subject on the basis of the eye position; and a second control unit that controls the imaging unit to capture a second image of the peripheral area at a second pixel density that is higher than the first pixel density. According to such an imaging system, it is possible to properly capture an image of the periphery of the eyes of the subject.
