Claim One:
1. An image accumulation device comprising: an input unit that inputs, as input images, images of shot locations; an image database storing specific locations each of which are uniquely associated with a corresponding peripheral region, a plurality of peripheral region coordinate information representing each of the peripheral regions, shot images associated with each specific location, and a plurality of incidental information each being added to one of the input images and including position information of the shot location of the input image and shooting time information of the input image, and data associations associating a single specific location with a single peripheral region in a one-to-one manner, and the shot images with the each specific location; and an identification unit that comprises: a search unit that searches, on the basis of the peripheral region coordinate information and the incidental information, for a single specific location associated with a peripheral region that includes the shot location of the input image, and the shooting time of the input image, and if the search is successful, the identification unit identifies the single specific location found by the search unit and stores in the database a data association associating the input images with the identified single specific location; and a rewriting unit which, when there is no peripheral region that includes the shot location of the input image, selects the peripheral region whose position information is closest to the shot location of the input image, and automatically rewrites the peripheral region coordinate information associated with the selected peripheral region so that the selected peripheral region is extended to include the shot location of the input image.
