According to one embodiment, a server device (SV) stores, in an omnidirectional image storage unit (21), omnidirectional images of a three-dimensional space photographed at a plurality of positions, for each floor of a facility. Where two images of the same floor photographed at different dates and times are displayed for comparison, an omnidirectional image whose photography position coordinates are closest to the photography position coordinates of a comparison reference image is selected from among all omnidirectional images to be compared. The angle of the selected omnidirectional image to be compared is adjusted such that it corresponds to the angle of a comparison reference image. Comparison display image data is generated in which the adjusted comparison image and the comparison reference image are arranged side by side and is transmitted to the user terminal (UT1).
