<p>PROBLEM TO BE SOLVED: To provide a device for deciding the breakdown of a shake sensor which decides whether the shake sensor is normal or broken down by checking the alignment state of the shake sensor incorporated in an optical device (a camera or a lens or the like), and to provide a camera system and an inter changeable lens equipped with the device. SOLUTION: This device decides the breakdown of the shake sensor 11 incorporated in the optical device 10 in order to detect the shake of the optical device 10, and is equipped with a decision starting means 17 for starting the decision of the breakdown of the sensor 11, a filter means 42 inputting a sensor signal outputted from the sensor 11 and making a signal component in a specified frequency band pass, and a decision means 48 deciding the breakdown of the sensor 11 based on the signal component in a specified time from start of the decision.</p> |
