Claim:
1. An inspection apparatus comprising: an optical system portion on which a plurality of reflected light rays corresponding to a plurality of observation directions with respect to an optical variable image device are incident and which images the plurality of reflected light rays incident thereon; an imaging portion that images the plurality of reflected light rays imaged by the optical system portion and thereby generates reflected light images corresponding to the plurality of respective observation directions; an object relation determination portion that determines whether or not there is a predetermined geometric difference between objects that are contained in reflected light images imaged by the imaging portion and corresponding to different observation directions by applying a predetermined geometric transformation to at least one of a first object contained in a reflected light image corresponding to a first observation direction to obtain a first object transformation and a second object contained in a reflected light image corresponding to a second observation direction that is different from said first observation direction to determine a second object transformation, and then determines whether or not the first object and the second object coincide with each other by comparing the first and second object transformations, wherein the object relation determination portion moves at least one of the first object and the second object in a predetermined movement direction for a predetermined movement amount; and an authenticity determination portion that determines authenticity of the optical variable image device based on a result of the determination by the object relation determination portion.
