ABSTRACT:
Subordinate images are produced by extracting parts of photographically obtained or externally supplied main image data of a predetermined image area for improving retrieval properties. First, subordinate image is produced by extracting part of photographically obtained or externally supplied main image data of a predetermined image area, and a second subordinate image is produced by extracting part of the image data of the first subordinate image produced by the first subordinate image producing means. Thus, the subordinate image can be produced from subordinate image data, increasing the freedom degree of the subordinate image production, and it is possible to extract only the necessary data.
