An image search device is provided which relatively easily outputs images that a user wishes to use for interpolation from among a large volume of stored image content data.The image search device includes: a degree-of-association database (102) which stores degrees of association between images; an input unit (103) which receives a first image and a second image; an interpolation range computing unit (104) which computes interpolation range including first photographing location of the first image and second photographing location of the second image; an imaging content inferring unit (107) which infers imaging content of interpolation images based on the degree of association between the first image and an image belonging to the interpolation range and the degree of association between the second image and the image belonging to the interpolation range; an interpolation image obtaining unit (108) which obtains interpolation images from among candidate images using the inferred imaging content; and an output unit (109) which outputs the interpolation images.
