The image signal analysis unit 242 analyzes the attributes of the user such as age, sex, height, face, clothes, facial expression, etc. by image processing in order to individually grasp the user from the input image signal, and the analysis The analyzed result is stored in the analysis result storage unit 243 (step S3).
Next, it is verified whether or not the child K exists in the analysis result. If the child K exists (step S4 YES), if the child K is on the board (step S11 YES) Then, it is determined whether or not the parent was accompanied at the time of entry (step S12). In this process, for example, the determination can be made from the result of the image processing of the building side monitoring camera 80 installed at the event venue or the entrance of the building. If the child is accompanied by the parent at the time of entry (YES in step S12), the child K is determined to be lost and user information is added to the lost child list from the user analysis data that is the analysis result of the image signal analysis unit 242 (step S13). ).

  In this case, if a lost child application is installed on a mobile terminal (smartphone or tablet) possessed by the guardian of the child K, the lost child information is displayed by the lost child application (steps S14 and S15). If the mobile terminal with the application installed is not possessed (NO at step S15), it is displayed as lost child information on the guidance display device 90 installed at the hall 4 on each floor (step S16). When the guardian or the staff issues the lost child information by viewing the display content of the guidance display device 90 (step S17 YES), or the guardian issues the lost child information from the portable terminal by viewing the lost child information displayed on the portable terminal. If this is the case (steps S18, S19 YES), the lost child guidance operation is performed to protect the lost child (steps S20, S21).

  For example, the disaster prevention center 70 that has received the lost child information notifies the elevator control device 50 to that effect, and drives the car to the floor where the lost child is located to protect the lost child. In this case, by using the hall speaker 42, anxiety is resolved by giving advice or guidance to the child K who is lost.

  As described above, according to the second embodiment, it is possible to detect a lost child effectively by image analysis using existing facilities such as the hall camera 22 and the car camera 23 installed in the elevator. In addition, since the lost child information can be notified to the portable terminal possessed by the guardian, the elevator facility can be used safely and safely for the guardian.
