PROBLEM TO BE SOLVED: To improve the accuracy of image retrieval.SOLUTION: An image processor 10 is provided, including a storage part 11 for storing a reference image Phaving a plurality of feature areas A, Awith a plurality of pairs of pixels set, and a feature amount based on luminance differences d, dbetween pixels calculated about the pairs of pixels, and an operation part 12 for calculating a feature amount based on luminance differences d, dbetween pixels about pairs of pixels set in a plurality of feature areas B, Bbelonging to an object image P, and determining whether to include an area similar to the reference image Pin the object image Pby using a feature amount about the feature areas B, Bof the object image P, and a feature amount about the feature areas A, Aof the reference image P. The operation part 12 uses a feature amount satisfying a condition set about the magnitudes of the luminance differences d, d, d, damong the feature amounts for determination. |
