PROBLEM TO BE SOLVED: To provide a similar image retrieving device capable of performing highly accurate similarity retrieval even when the illumination conditions of a key image and a search image are different. SOLUTION: The histograms of the key image and a search image 100 are inputted to a similarity calculating part 8. On the basis of limit conditions set by a limit condition setting part 9, an appearance parameter calculating part 10 calculates the model parameter of a color appearance model. On the basis of the parameter calculated by the appearance parameter calculating part 10, a normalizing part 8a of the similarity calculating part 8 normalizes the histogram of the search image. The similarity calculating part 8 calculates the similarity between the normalized histogram of the search image and the histogram of the key image. On the basis of the similarity calculated by the similarity calculating part 8, a searched result discriminating part 11 discriminates whether that search image is the candidate image of retrieval or not. |
