PURPOSE: A system and a method for the group control of elevators by using a camera are provided to satisfy customers and to cut down the costs of elevator operation by reducing the average waiting time of passengers. CONSTITUTION: Cameras are installed in each floor. A group control unit allocates the elevator optimal to the hall calls of each floor by considering the hall calls of each floor, the number of waiting passengers, and the interior condition of the elevators. When the arrival pattern of passengers is changed, a control tuning unit generates an elevator allocation function by receiving a request from the group control unit. If one elevator is not enough for a hall call, more than two elevators are allocated previously. Thereby, the waiting time of the passengers is reduced.
