Image switching device for vehicle

An image switching device for a vehicle includes: a reference distance determination device that determines a reference distance; and a determination device that prohibits an image display device from displaying an image captured by an on-board camera, based on a feature that a detection distance from an object to a vehicle is longer than the reference distance, and allows the image display device to display the image captured by the on-board camera, based on a feature that the detection distance is shorter than the reference distance. The reference distance determination device shortens the reference distance in a case where an absolute value of acceleration of the vehicle is a second value which is greater than a first value, compared to a case where the absolute value of acceleration of the vehicle is the first value.
