Abstract
A technique for displaying a scale-changed view of a narrow-angle branch intersection in an easily visually recognizable manner through simple processing. A map display system that displays a map on a display section includes: narrow-angle branch intersection determination code for determining whether or not a guide target intersection is a narrow-angle branch intersection at which an intersection angle between roads is smaller than a predetermined threshold; and a scale-changed view display for displaying a scale-changed view, which is obtained by changing a scale of the guide target intersection included in the map such that a value obtained by dividing a horizontal scale change rate by a vertical scale change rate is larger than 1, on the display section in the case where the guide target intersection is the narrow-angle branch intersection.
