Abstract
A query device part image and an assembly drawing image from a drawing database which is a search target are input. The assembly drawing image is classified into text and non-text areas in the layout analysis unit 10. In the device part extraction unit 11, part images are extracted from non-text areas. The device part comparison unit 12 collates the extracted part image and the query device part image.
