Imaging device, control method thereof, and imaging system

An imaging system including an imaging device in which a lens device is able to be installed via a mount part, comprising:

• at least one processor and memory holding a program which makes the processor function as:
• a correction unit configured to perform image blur correction through driving of an imaging element;
• and
• a control unit configured to control driving of the correction unit based on detection information of a detection unit configured to detect shaking of the lens device or the imaging device,
• wherein, when a first lens device is installed in the imaging device, the control unit determines a range of the amount of drive control using information acquired from a storage unit of the first lens device, and
• when a second lens device is installed in the imaging device, the control unit determines the range of the amount of drive control using information acquired from the storage unit of the imaging device.

A control method performed using an imaging device in which a lens device is able to be installed via a mount part, comprising:

• acquiring, by a control unit, detection information of a detection unit configured to detect shaking of the lens device or the imaging device and determining a range of an amount of drive control of a correction unit included in the imaging device;
• and
• performing image blur correction when the correction unit drives an imaging element included in the imaging device in accordance with the amount of drive control,
• wherein, in the determining, the control unit determines the range of the amount of drive control of the correction unit on the basis of a difference between a second length and positioning accuracy when the imaging element is positioned at a center of the mount part using the correction unit and
• wherein 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.
