1. A display image formation apparatus comprising:
- a memory that stores instructions; and
a processor that, when executing the instructions stored in the memory, performs operations comprising;
selecting an omni-directional camera from a plurality of omni-directional cameras based on a positional relationship between a designated position on a plan map and positions of the plurality of omni-directional cameras;
determining an enlargement amount of an image region, as a parameter, to extract the image region from an omni-directional image captured by the selected omni-directional camera for display, according to a distance, in a plane of the omni-directional image, from a center of the omni-directional image captured by the selected omni-directional camera to the designated position in the omni-directional image;
determining the image region having the determined enlargement amount in the omni-directional image captured by the selected omni-directional camera using the parameter;
extracting the determined image region from the omni-directional image;
enlarging the extracted image region having the determined enlargement amount;
generating a display image including the enlarged extracted image region overlapping the plan map; and
outputting the generated display image to a display,wherein the image region is determined such that, as a size of the image region extracted from the omni-directional image captured by the selected omni-directional camera increases, the distance from the center of the captured omni-directional image, in the plane of the captured omni-directional image, becomes shorter and the enlargement amount decreases, and the extracted image region is processed by pixel interpolation to enlarge the extracted image region.

Abstract
A display image formation device enables, in an intuitive manner, designation of a location which the user wishes to see when multiple panoramic images obtained by multiple panoramic cameras are present, and enables display of the image for a designated site in a suitable state. One panoramic camera is selected from multiple panoramic cameras on the basis of the positional relationship between a designated position on a planar map and the multiple panoramic cameras. An extracted image region, which is extracted from the image photographed by the selected panoramic camera, is determined. A display image is generated such that the extracted image is arranged on the planar map.
