摘要：
A first equalizer generates a vibration-component signal indicating the amount of movement of an image pickup apparatus according to an output signal of a vibration detecting element for detecting the vibration of the image pickup apparatus. The second equalizer generates a drive signal used to control a driver element to correct the position of a lens or image pickup devices, based on the output signal of a position detecting element for detecting the position of the lens to be driven or the image pickup devices to be driven and the vibration-component signal. A control unit verifies the operations of the driver element, the position detecting element, the vibration detecting element and the first equalizer, based on the output signal of the position detecting element and the vibration-component signal.
