    摘要: Method and apparatus for obtaining distance data from an object to a lens by obtaining an image of the object by an image input unit for forming an image of the object through the lens on an image receiving plane. Two observed images Is and Is' with different blurs from the image input unit are obtained by making a position of the lens and/or a position of the image receiving plane with regard to the object different by a minute distance .DELTA.z. A filtering process is then performed by applying a filter to the two input observed images Is and Is', thereby providing two output images Fs and Fs'. The distance a up to the object is calculated by using the two output images Fs and Fs' obtained by the filtering process based on the relation between the two output images Fs and Fs' and radius s of the blur and the distance a from the lens to the object.

    摘要: The present invention has been made to provide a technique capable of easily preventing the third party from misusing the data related to an individual physical feature in the case where individual authentication is performed based on the physical feature. An individual authentication system that authenticates an individual based on his or her physical feature comprises an authentication information acquisition section that acquires, at the time of authentication of an individual, information related to a state in which predetermined processing has applied to predetermined physical feature of the individual as authentication information for authentication determination; a registration information acquisition section that acquires the previously registered information related to a state in which predetermined processing has applied to predetermined individual physical feature as registration information for authentication; and an authentication determination section that determines authentication of the authentication information acquired by the authentication information acquisition section based on the registration information acquired by the registration information acquisition section.
