An input unit receives a first image that captures a scene in front of a vehicle or a scene in front of a user on board a vehicle at a first point of time. A generator generates a third image showing a result of prediction of the scene in front at the first point of time, based on a second image that captures the scene in front at a second point of time preceding the first point of time. A display controller controls display of information presentation based on a result of comparison between the first image received by the input unit and the third image generated by the generator using a predetermined criterion.
