IMAGING APPARATUS |
| 摘要 |
An imaging apparatus according to the present disclosure includes: a focus lens, a motor for driving the focus lens, an origin detection unit for detecting an arrival of the focus lens at a reference position, a drive amount detection unit for detecting an amount of drive of the focus lens driven by the motor, and a controller for recognizing a position of the focus lens based on an output from the drive amount detection unit and for controlling the position of the focus lens. The controller receives a detection signal from the origin detection unit during driving the focus lens, and determines an occurrence of step-out of the motor based on both the received detection signal and the position of the focus lens recognized by the controller. |
