In the following, the front imaging device 120-1, the right imaging device 120-2, the rear imaging device 120-3, and the left imaging device 120-4 are collectively referred to as the imaging device 120.

The image information acquisition system 1 provides an image of the surroundings of the vehicle 900 for each of the vehicles 900.
The vehicle 900 corresponds to the example of a moving body. However, the scope of application of the image information acquisition system 1 is not limited to the vehicle, and various moving objects capable of capturing surrounding images can be used. For example, the image information acquisition system 1 may be applied to a ship.
Each of the vehicle-mounted devices 100 is mounted on the vehicle 900, and acquires an image of the surroundings of the vehicle 900 on which the vehicle-mounted device 100 itself is mounted. The vehicle 900 corresponds to the example of a moving body. The in-vehicle device 100 corresponds to an example of a mobile loading device.

Further, a vehicle 900 on which the in-vehicle device 100 or a portion thereof is mounted is referred to as a own vehicle 900. A vehicle 900 other than the vehicle 900 on which the in-vehicle device 100 or a portion thereof is mounted is referred to as another vehicle 900.
Further, the vehicle-mounted device 100 including a part of the vehicle-mounted device 100 itself is referred to as its own vehicle-mounted device 100. An in-vehicle device 100 other than the in-vehicle device 100 including a part of the in-vehicle device 100 itself is referred to as another in-vehicle device 100.
The in-vehicle device 100 is configured by using a computer such as a microcomputer.

The first communication unit 110 communicates with another device.
The transmission unit 111 executes transmission in the first communication unit 110. In particular, when the detection unit 191 detects a defect in the photographing device 120 or a defect in the image captured by the photographing device 120, the transmitting unit 111 can obtain the identification information of the photographing device 120 or the image in which the detection unit 191 detects the defect.
