PROBLEM TO BE SOLVED: To acquire a reference image similar to an input image with high accuracy.SOLUTION: A feature amount calculation part 32 calculates a feature amount about each of reference images, a partial area determination part 40 determines a partial area of a reference image, which is also the partial area to be different from the other reference images on the basis of the calculated feature amount of the reference image and the feature amount of each reference image other than the calculated reference images and similar to the reference image, a partial feature amount calculation part 50 calculates a feature amount about each of the reference images, and about a partial area of the determined reference image, an input image feature amount calculation part 60 calculates a feature amount from an input image, a similarity calculation part calculates similarity between the input image and the reference image on the basis of the calculated feature amount of the input image and the calculated feature amount of the partial area of the reference image about each of the reference images, and an output part 90 outputs a reference image similar to the input image on the basis of each of calculated similarities.SELECTED DRAWING: Figure 1 |
