  • Patent number: 11968452
    Abstract: An imaging apparatus includes: an imaging sensor that captures an object image formed through an interchangeable lens to generate image data; a driver that performs image blur correction by moving the imaging sensor in a plane perpendicular to an optical axis; and a controller that causes the driver to move the imaging sensor. The controller causes the driver to move the imaging sensor automatically, thereby detecting a movable amount of the imaging sensor that does not cause a vignetting in the captured image at a time when moving the imaging sensor for image blur correction, and causes the driver to move the imaging sensor within a range of the detected movable amount.
