<P>PROBLEM TO BE SOLVED: To perform a zoom operation with excellent quality. <P>SOLUTION: An imaging optical system 21 is configured by using a zoom lens 211, a focus lens 212, etc.; an optical system driving unit 22 is configured to drive the imaging optical system 21; and a controller 43 configured to prevent an avoidance operation of avoiding an influence of hysteresis of a position of the zoom lens having the hysteresis with respect to a driving direction of the zoom lens in a first operation mode of recording a moving image, and to perform the avoidance operation in a second operation mode different from the first operation mode. Therefore, even when the zoom operation is performed during recording of the moving image, it is possible to prevent the variation in an angle of view due to the avoidance operation of avoiding the influence of the hysteresis. Moreover, since the avoidance operation is performed in the second operation mode, the influence of the hysteresis is avoided, so that the zoom lens can be positioned at a desired position. Therefore, the zoom operation with excellent quality can be performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
