1. A display system comprising:
a road surface undulation estimation that estimates undulation of a road surface;
a superimposing position determination that determines, based on the undulation estimated by the road surface undulation estimation, a superimposing position at which a content is to be displayed by being superimposed on a foreground; and
a display that displays the content with the content being superimposed on the foreground, at the superimposing position determined by the superimposing position determination, wherein
the road surface undulation estimation includes:
a road surface undulation information obtaining program obtains a plurality of road surface undulation information items indicating the undulation of the road surface at a plurality of points, the road surface undulation information items being calculated based on a plurality of images generated when an imaging program provided to a mobile body performs image capturing a plurality of times;
a determination program that determines whether or not each of the plurality of road surface undulation information items obtained by the road surface undulation information obtaining programming satisfies a predetermined condition; and
an estimation program that estimates the undulation of the road surface based on one or more road surface undulation information items which are determined by the determination program to satisfy the predetermined condition among the plurality of road surface undulation information items;
wherein each of the plurality of road surface undulation information items includes a relative position of an object with respect to the mobile body, the object being within a capturing range of the imaging program, and
wherein the predetermined condition is a condition that a change amount between relative positions included in the plurality of road surface undulation information items is within a predetermined threshold range.
