Image display device

An image display device connected to a display device that displays information to a remote operator that remotely instructs a vehicle, comprising:

• a processor configured to:
• acquire external sensor data detected at a first time point by an external sensor that detects information on an external environment of the vehicle from the vehicle;
• acquire internal sensor data detected at the first time point by an internal sensor that detects a travel state of the vehicle from the vehicle;
• determine a position of the vehicle at a second time point that is a future time point after a predetermined time has elapsed from the first time point, based on the internal sensor data at the first time point;
• display a monitoring image indicating surroundings of the vehicle on the display device based on the external sensor data at the first time point;
• superimpose an object indicating the position of the vehicle at the second time point at a position on the monitoring image corresponding to the position of the vehicle at the second time point,
• calculate a delay time of communication with the vehicle;
• determine an acceptable range of the position of the vehicle at the second time point based on the delay time;
• and
• superimpose an object indicating the acceptable range at a position on the monitoring image corresponding to the acceptable range.
