Abstract
Filters that have transmission wavelength characteristics that change in stages are provided. An object being inspected is specified based on spectrum characteristics that are created from image data of images that have passed through the filters and been picked up by a CCD camera. The image data as well as the spectrum characteristic data are recorded as a database on a hard disk. Then, a comparison is made between this database and the data of the object being inspected.
