Periphery image display control device

A periphery image display control device including a display control unit for displaying an image photographed by a camera which photographs a periphery area around an own vehicle on a display unit comprising:

• a prediction unit for predicting a travel path area which a vehicle-body of the own vehicle will pass through when the own vehicle travels along a predicted travel path;
• an obstacle detection unit for obtaining obstacle information including locations of obstacle points which are included in at least one of obstacles present in the travel path area and whose heights become higher as the obstacle points are farther from the own vehicle, and heights of the obstacle points in relation to the own vehicle;
• and
• a determination unit configured to:
• determine whether or not a first ratio is greater than a threshold, the first ratio being a ratio of a subtraction value obtained by subtracting a height of a first obstacle point which is nearer from the own vehicle between two of the obstacle points which are adjacent to each other in a direction of the predicted travel path from a height of a second obstacle point which is farther from the own vehicle between the two of the obstacle points, to a distance between the first obstacle point and the second obstacle point along the predicted travel path, and the threshold being a value which is preset based on a second ratio of a height between a ground point of a front wheel of the own vehicle and a bottom end at a front end of the vehicle-body of the own vehicle to a distance between the front end and the ground point in a horizontal direction of the vehicle-body;
• and
• determine that the obstacle including the second obstacle point is an alert obstacle, when the first ratio is determined to be greater than the threshold, and
• wherein the display control unit is configured to display an alert screen for causing the driver to pay attention to the alert obstacle on the display unit.
