Abstract: An imaging apparatus includes an interchangeable lens, and a camera body. The interchangeable lens includes a correction lens, a lens driver, and a first controller. The camera body includes an image sensor, a sensor driver, and a second controller. The first or second controller selects one of the interchangeable lens and the camera body, in accordance with a level of correction capability to perform the image stabilization. Corresponding to the selected one, one driver of the lens driver and the sensor driver performs the image stabilization for the image blur within a predetermined range. The other driver corresponding to non-selected one performs the image stabilization for a remaining portion of the image blur exceeding the predetermined range.

Abstract: An image pickup apparatus of the present invention is an image pickup apparatus including an ultrasonic motor 35 that moves a focus lens 24, and further including a correction control part 100 that operates the ultrasonic motor 35 under a predetermined condition. The correction control part 100 is capable of executing a correction process by measuring a frequency characteristic of an applied voltage at the time of operating the ultrasonic motor 35 at a predetermined rotation speed, comparing the frequency characteristic with a preset reference frequency characteristic, and correcting the frequency characteristics on the basis of a difference between the frequency characteristic and the reference frequency characteristic so as to calculate a correction frequency characteristic. Accordingly, even when the frequency characteristic of the ultrasonic motor varies due to wear of the ultrasonic motor and mechanical components coupled thereto, a stable drive can be maintained over a long time.
