<p>PROBLEM TO BE SOLVED: To consecutively and smoothly control a shake correction device after it is restarted in the case shake correction control is required again by constituting the shake correction device so that the actions of the device may not be stopped but controlled by judging that the shake correction control is not required. SOLUTION: A shake correction control part is composed of a microcomputer for vibration-proof control 3, a microcomputer for an ultrasonic motor 16, a microcomputer for communication 24, which are in a lens device 1, and a microcomputer for a body 25 in a body device 2. When a state where the output value of a shake detection part is smaller than a previously set specified value is continued for a fixed time or more, the shake correction control part changes the decided output value of a shake correction driving part to a small value so as to keep the shake correction device finely acting. In the case the output value of the shake detection part becomes equal to or above a specified value after changing to the small value, it is immediately restored to the output value of the shake correction driving part decided based on the output value of the shake detection part.</p> |
