An optical member drive control apparatus includes an acquiring unit configured to acquire first information corresponding to a movement speed of an optical member when a movement of the optical member is controlled and second information corresponding to a movement amount of the optical member; and a controller configured to output a signal to an actuator that moves the optical member and that can detect a drive amount of the actuator per unit time. The controller includes at least a first mode that carries out closed loop control of the actuator according to the detection result of the drive amount of the actuator per unit time and a second mode that carries out open loop control of the actuator, and the controller selects the first mode or the second mode based on the first information and the second information that have been acquired by the acquiring unit.

Imaging apparatus and control method for same

An image pickup apparatus includes a first drive unit, a first lens unit configured to be driven by the first drive unit to perform a magnification-varying operation, a second drive unit, a second lens unit configured to be driven by the second drive unit, and a controller configured to control the first drive unit and the second drive unit so as to drive the second lens unit with reference to a position of the first lens unit in performing the magnification-varying operation. The controller controls the second lens unit so as to move only in a first direction in performing the magnification-varying operation.

Image pickup apparatus that drives plural lens units using motors different from each other and drive control method of lens

In a mode in which a lens barrel need not be extended, if it is determined that a vibration is larger than a reference value, the lens barrel is driven so as to be retracted to a predetermined position.

Control apparatus, imaging apparatus, and control method for the imaging apparatus

An imaging apparatus which can capture a still image while capturing a moving image, can capture images in consideration of the aspect ratio settings of the moving image and the still image. For example, in the case where a user instructs to capture the still image while capturing a moving image, the still image is captured in an aspect ratio of recording the moving image. The captured still image can be used to complement a missing frame of the moving image.

Imaging apparatus and control method thereof, storage medium and program

Evaluation values are extracted at first timings with respect to a movement of a focus lens, and evaluation values are extracted at second timings having higher frequency than the first timings on the basis of the evaluation values extracted at the first timings. Then, even if the evaluation values have been extracted at the second timings in such a way, the focus lens is moved on the basis of the evaluation values extracted at the first timings. Thereby, the fast and suitable movement of AF can be implemented.
