Abstract:
1. A vibration correction control circuit for correcting an optical axis of an image pickup apparatus in response to a vibration thereof, the circuit comprising: a vibration-component signal generating unit configured to generate a vibration-component signal indicating an amount of movement of an image pickup apparatus according to an output signal of a vibration detecting element for detecting a vibration of the image pickup apparatus; a driver signal generating unit configured to generate a drive signal used to control a driver element to correct a position of a lens, based on an output signal of a position detecting element for detecting the position of the lens to be driven and the vibration-component signal; and a bit length converting circuit for a floating-point number configured to convert the bit length of the output signal of the vibration detecting element expressed by the floating-point number, the bit length converting circuit comprising:
