To provide a technique for reducing the possibility that the visibility of information displayed in a balloon indicating a route is deteriorated.SOLUTION: A route display system includes: a route display unit for displaying a route on a screen; a center-of-gravity position acquisition unit that acquires a position of a center of gravity of a plurality of shape points indicating a shape of the route when the route is displayed on the screen; and a balloon display unit that displays a balloon including a main body that displays information indicating characteristics of the route and a pin that extends from the main body and that points to a set point on the route. When the set point set based on the position of the center of gravity is in an end region in the screen, the balloon is displayed so that the pin points to the set point from the opposite side of the edge of the screen based on the set point.SELECTED DRAWING: Figure 1
【課題】経路を指し示す吹き出しに表示される情報の視認性が低下する可能性を低減する技術の提供。【解決手段】経路を画面に表示する経路表示部と、前記経路を前記画面に表示した場合の、当該経路の形状を示す複数の形状点の重心の位置を取得する重心位置取得部と、前記経路の特徴を示す情報を表示する本体部と前記本体部から延び前記経路上の設定地点を指し示すピンとを含む吹き出しを表示する吹き出し表示部と、を備え、前記重心の位置に基づいて設定される前記設定地点が前記画面内の端部領域にある場合には、前記設定地点を基準として前記画面の端の反対側から前記ピンが前記設定地点を指し示すように前記吹き出しが表示される、経路表示システムを構成する。【選択図】図1
