Entrance management apparatus and entrance management method

Abstract

Feature amounts of faces of visitors photographed at a first gate are registered in a registration section in relation to entrance permission time information items each of which defines a period of time during which entrance through a second gate provided inside the first gate is permitted. At the second gate, the face of the visitor is photographed and the feature amount of the photographed face of the visitor is collated with the face feature amounts registered in the registration section. Entrance through the second gate is controlled based on the result of collation and the entrance permission time information registered in the registration section.
