pieces of image data such as moving images or static images recorded in analog or digital and in which the retrieval of

desired image data is performed by using the extracted char acteristic values and/or the pieces of extracted attribute information. 2. Description of Related Art FIG. 1 shows the con?guration of a system as an example

of a conventional image retrieval processing system. This system is disclosed in a letter “Synthesis and Evaluation of

the Image Database with Fully Automated Keyword Extrac tion by State Transition Model and Scene Description Lan guage” edited by Institute of Electronic Information and Communication Engineers of Japan, D-II Vol. J79-D-II No.4, pp.476*483, April of 1996. In this system, static

In the unit 105, an operation 106, in which a user 107 selects one predicate from predicates de?ned in advance and describes the selected predicate, is required, and the selected predicate is output as a scene description keyword 109. In a retrieval tool 102, conception keywords and scene description keywords are prepared in advance. A user 111 selects one conception keyword and one scene description
