• a capturing process of capturing a measurement target place using a camera;
• a reception process of receiving an image captured by the camera;
• a number-of-people determination process of calculating a number of people in the measurement target place based on an image received in the reception process;
• an allocation process of allocating a car according to the number of people in the measurement target place calculated in the number-of-people determination process;
• and
• an abnormality determination process of determining an abnormality of the camera or a transmission path based on a reception status of an image in the reception process, wherein
• when an abnormality is determined in the abnormality determination process, the number-of-people determination process refers to a detection value of a sensor installed in the car or the measurement target place to calculate the number of people.

An elevator comprising:

• an in-car camera that is installed in a car and captures inside of the car;
• a reception unit that receives an image captured by the in-car camera;
• a number-of-people setting unit that calculates a number of people in a car based on an image received by the receiving unit;
• an allocation command unit that allocates a car according to the number of people determined by the number-of-people determination unit;
• and
• an abnormality determination unit that determines an abnormality of the in-car camera or a transmission path based on a reception status of an image captured by the in-car camera in the reception unit, wherein
• when the abnormality determination unit determines an abnormality, the number-of-people setting unit refers to a detection value of a load sensor installed in the car to calculate the number of people in the car.
