Abstract
A lens device is able to be installed in an imaging device via a mount part. The imaging device comprises a correction unit performing image blur correction through driving of an imaging element and a control unit which controls driving of the correction unit. The control unit determines a range of an amount of drive control of the correction unit on the basis of a difference between a second length and a positioning accuracy when the imaging element is positioned at the center of the mount part using the correction unit. The second length is obtained by subtracting a diagonal length associated with an imaging range of the imaging element from a first length corresponding to a closest distance to the center of the mount part from a circumference of an imaging circle when viewed from an optical axis direction of an imaging optical system included in the lens device.
