Abstract:
1. A camera system for imaging a subject, the camera system comprising: a camera body including an imaging unit for imaging the subject, and a body control unit for controlling the imaging action of the imaging unit; and an interchangeable lens including a shake detection unit for detecting shake of the camera system, an image blur correction unit for adjusting the optical path from the subject to the camera body and thereby correcting the blurring of an image caused by shaking of the camera system, and a lens control unit for controlling the correction action of the image blur correction unit according to the amount of shake detected by the shake detection unit, wherein the body control unit is capable of sending and receiving information to and from the lens control unit, and stores body information related to the camera body, the lens control unit stores lens information related to the image blur correction unit, one of the body control unit and the lens control unit determines one of timings including correction timing at which the image blur correction unit starts the correction action, exposure timing at which the imaging unit starts exposure, and exposure preparation timing at which the imaging unit starts exposure preparation, based on the body information and the lens information, the body information includes an exposure preparation time required from the point when the camera body begins exposure preparation until the exposure preparation is completed, the lens information includes a correction stabilization time required from the point when the image blur correction unit is actuated until a specific image blur correction effect is obtained, and one of the body control unit and the lens control unit determines one of the correction timing, the exposure timing, and the exposure preparation timing, based on the exposure preparation time and the correction stabilization time.
