摘要： A lens control apparatus, and an interchangeable lens including the lens control apparatus, are provided which can obtain, in zoom tracking operation, excellent optical images at subject distances in a wider range. A lens control apparatus controls drive of an optical system including a first and a second focus lens for adjusting a focus state and a zoom lens for adjusting an angle of view. The lens control apparatus includes: a first driver that drives the first focus lens; a second driver that drives the second focus lens; a controller that controls the first and second drivers; and a storage unit that stores first and second tracking data, the first and second tracking data each being information that associates a position of the first and second focus lenses respectively with a position of the zoom lens for focusing on a subject.

摘要： 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.
摘要翻译：本发明的图像拾取装置是包括移动聚焦透镜24的超声波马达35的图像拾取装置，并且还包括在预定条件下操作超声波马达35的校正控制部100。校正控制部100能够通过以预定的转速测量超声波马达35的运转时的施加电压的频率特性，将频率特性与预先设定的基准频率特性进行比较来进行校正处理，基于频率特性和参考频率特性之间的差异来计算校正频率特性。因此，即使当超声波马达的频率特性由于超声波马达的磨损和与其耦合的机械部件而变化时，可以长时间保持稳定的驱动。
