摘要： A first face detecting section detects the face of a passerby based on an image obtained from a first camera set to be easily recognized by the passerby. A second face detecting section detects the face of the passerby based on an image obtained from a second camera set so that the camera will be difficult to be recognized by the passerby. A classifying section classifies the passerby based on the detection results of the faces by the first and second face detecting sections and adjusts a threshold value for authentication based on the classification result. The face collating section calculates the similarity between the face of the passerby and each of faces of registrants and determines whether the passerby is a registrant or not according to whether the degree of calculated similarity is not lower than the adjusted threshold value for authentication.
