ABSTRACT:
An apparatus for inspecting a blur correction function of a blur correction camera, which comprises an optical axis changing unit for changing the optical axis of a photographing optical system so as to correct a blur generated by a vibration, a displacement detecting unit for detecting a displacement of the photographing optical system by the optical axis changing unit, a maximum/minimum displacement detecting unit for detecting maximum and minimum values of an output value from the displacement detecting unit, and an angular velocity detecting unit for detecting an angular velocity caused by the vibration, includes: an information exchange unit for exchanging information with the blur correction camera, a vibration applying unit for applying a sinusoidal vibration having a predetermined angular amplitude in a detection direction of the angular velocity of the angular velocity detecting unit of the blur correction camera, a reading unit for reading an output value from the maximum/minimum displacement detecting unit of the blur correction camera upon application of the sinusoidal vibration, and a discrimination unit for discriminating, based on the output value read by the reading unit, whether or not the blur correction function of the blur correction camera is normal.
