摘要： An apparatus is provided for extracting feature information from images of an object. The images of the object include a first in-focus image and a second soft focus image. The apparatus includes an optical system that includes at least one common image forming optical element. The optical system forms the first image and the second image of the object in different focus conditions. A photosensitive sensor converts the first image and the second image formed by the optical system to first and second image signals. An extracting feature device extracts the feature information of the object from a difference between the first image signals and the second image signals.
