Next, the face image automatically specified and manually specified from the input image is specified as the face image to be determined. Next, a similar face image search is performed on the feature amount DB with time reduction. Next, how many retrieval results are less than or equal to a predetermined threshold value (high similarity degree) is calculated, and if the number of retrieval is large, it is assumed that the number of times of appearance is high and the possibility of wandering is high, the number of searches Is small, it is determined that the number of times of appearance is small and the possibility of wandering is low. Finally, the similarity between the face of the resident registered in advance and the person with the large number of searches is calculated, and if the similarity is high, it is determined as a resident regardless of the previous determination.(FIG.
