<p>PROBLEM TO BE SOLVED: To improve accuracy of retrieval of images by utilizing a past retrieval result.SOLUTION: Acquisition means 101 acquires a photographic image and positional information indicating the position where the photographic image is captured. Information specification means 102 specifies other positional information indicating the position in the same region as the position indicated by the positional information acquired by the acquisition means 101. Extraction means 103 extracts a similar image similar to the image acquired by the acquisition means 101 from a plurality of images respectively representing certain objects, and extracts an image by using the first extraction image extracted previously as the similar image of the image acquired with the positional information specified by the information specification means 102 among the plurality of images. In detail, the extraction means 103 extracts the image by increasing the priority of the image representing an object approximate to the object represented by the first extraction image in the retrieval among the plurality of the images and reflecting the priority.</p> |
