A keyword determining section determines a keyword among a search query input by a user. A related word searching section searches a thesaurus database and retrieves words related to the determined keyword and information on relevancy of each related word to the keyword. Based on the keyword and its related words, an image searching section retrieves images from an image database. The search result by the image searching section is displayed on a monitor in a manner to reflect mutual relations between the retrieved images, such that images corresponding to the keyword are displayed in a center section, whereas images corresponding to broader or super-ordinate words to the keyword are arranged in an upper section, and images corresponding to narrower or subordinate words to the keyword are arranged in a lower section. Other images hit with synonyms and other related words to the keyword are arranged in side sections.
