The detection device 40 detects the presence of a driver in the driver seat 16 and the presence of a passenger in the passenger seat 18 from the captured video. An image recognition process is performed for these detections, but since a known technique may be used, description thereof is omitted here. In addition, when a driver is called a 1st user, a passenger is called a 2nd user. As described above, in the present embodiment, since the transition from the first state to the second state is an object of description, the detection device 40 first detects the presence of the driver and the presence of the passenger, and then follows this. Thus, the presence of the driver and the absence of the passenger are detected. The detection device 40 outputs the detection result to the display control device 50.

  The receiving unit 52 is connected to the detection device 40 and receives a detection result from the detection device 40. Here, the content of the detection result is switched from the presence of the driver and the presence of the passenger to the presence of the driver and the absence of the passenger. Thus, the number of users present in the vehicle is switched from “2” to “1”. The application processing unit 54 executes the driver application and the passenger application. Note that a plurality of driver applications and a plurality of passenger applications may be executed. Since a known technique may be used for execution of these applications, description thereof is omitted here. The storage unit 56 stores a history of driver applications executed in the past by the application processing unit 54, and stores a history of passenger applications executed in the past by the application processing unit 54. In addition, the storage unit 56 stores application priorities.

  The control unit 58 controls display of a driver application screen and a passenger application screen executed by the application processing unit 54. When the detection result received by the reception unit 52 indicates the presence of the driver and the passenger, the driver application screen is displayed on the first area 22 of the display device 20 and the second area 24 of the display device 20 is displayed. To display the passenger application screen. On the other hand, when the detection result received in the reception unit 52 is switched between the presence of the driver and the absence of the passenger, the control unit 58 keeps the driver application screen displayed in the first region 22 of the display device 20. Then, a screen of an application other than the passenger application is displayed in the second area 24 of the display device 20.
