SOLUTION: A query image is provided for an image search engine executing image retrieval based on a multi-resolution model, and a first retrieval result is obtained. Then, designation of correct and/or incorrect about the image included in the first retrieval result is accepted. Next, weight on a degree of similarity for each of resolutions is calculated in accordance with the designation of correct and/or incorrect. After that, with the usage of the calculated weight, the degree of similarity between the query image and the retrieved image is re-calculated by the image search engine. Thus, a second retrieval result is obtained. Further, a document for output is generated wherein the images by the second retrieval result are arranged in descending order of the re-calculated degree of similarity. COPYRIGHT: (C)2010,JPO&INPIT
