<P>PROBLEM TO BE SOLVED: To provide an imaging device capable of properly imaging a moving image. <P>SOLUTION: An imaging device includes: a receiving part 21 for receiving a focal-length of an optical system from a lens barrel 3 provided with an optical system having a focal adjustment lens 33; a determination part 21 for determining whether or not the focal-length of the optical system is equal to a predetermined value or more; a mode setting part 28 capable of setting a moving image acquisition mode; a drive part 331 for driving a focus adjustment lens 33; and a control part 21 for controlling a driving speed of the focus adjustment lens 33. In the moving image acquisition mode, when the focal-length of the optical system is determined to be less than a predetermined value, the control part 21 limits the driving speed of the focal adjustment lens 33 not to exceed a first upper limit speed, and when the focal-length of the optical system is determined to be more than the predetermined value, the control part 21 limits the driving speed of the focus adjustment lens 33 not to exceed a second upper limit speed, which is faster than the first upper limit speed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
