Provided is an image search device which relatively easily searches a large amount of stored images for images that a user wishes to use for interpolation, and which includes: an interpolation range computing unit (103) which computes, as an interpolation range, a range of an area including a first photographing location where a first interpolation target image was taken and a second photographing location where a second interpolation target image was taken; an interpolation image candidate obtaining unit (104) which obtains, as candidate images, images whose photographing location are included in the interpolation range from the plurality of images; and an interpolation image selecting unit (106) which selects, from the candidate images, an image having a greater subject distance, which is a distance between a subject and an imaging device when the image was taken, as a traveling speed between the first photographing location and the second photographing location increases.
