Camera system and camera body

1. A camera system for forming an image of a subject, comprising:

a camera main body having an imaging unit configured to form an image of the subject, a main body shake detector configured to detect shake of the camera system, a main body image blur corrector configured to correct image blur produced by the shake, and a main body controller configured to control the main body shake detector and the main body image blur corrector; and

an interchangeable lens arranged to be removably attachable to the camera main body, having a lens shake detector configured to detect the shake, a lens image blur corrector configured to correct image blur produced by the shake, and a lens controller electrically connected to the main body controller and configured to control the lens shake detector and the lens image blur corrector,

the main body controller having a selector configured to select either a first combination of the main body image blur corrector and the lens shake detector or a second combination of the lens image blur corrector and the main body shake detector, and a switching part configured to activate one of the first combination or the second combination while deactivating the other of the first combination or the second combination, thereby detecting the shake of the camera system and correcting the image blur produced by the shake.

2. The camera system according to claim 1 ,

wherein the selector selects the lens image blur corrector when the main body shake detector is selected, and selects the main body image blur corrector when the lens shake detector is selected.

3. The camera system according to claim 2 ,

wherein the main body controller holds main body information pertaining to the camera main body,

the lens controller holds lens information pertaining to the interchangeable lens, and

the selector selects either the main body or the lens shake detector on the basis of the main body information and lens information.

4. The camera system according to claim 1 ,

wherein the selector selects the lens shake detector when the main body image blur corrector is selected, and selects the main body shake detector when the lens image blur corrector is selected.

5. The camera system according to claim 4 ,

wherein the main body controller holds main body information pertaining to the camera main body,

the lens controller holds lens information pertaining to the interchangeable lens, and

the selector is configured to select either the main body or lens image blur corrector on the basis of the main body information and lens information.

6. The camera system according to claim 1 ,

wherein the selector selects preset shake detector from the main body and lens shake detector when selecting the shake detector, and selects preset image blur corrector from the main body and lens image blur corrector when selecting the image blur corrector.

7. A camera main body to which an interchangeable lens is removably attachable, constituting, along with the interchangeable lens, a camera system for forming an image of a subject, and having a lens shake detector configured to detect shake of the camera system, a lens image blur corrector configured to correct image blur produced by the shake, and a lens controller configured to control the lens shake detector and the lens image blur corrector, comprising:

an imaging unit configured to form an image of the subject;

a main body shake detector configured to detect shake of the camera system;

a main body image blur corrector configured to correct image blur produced by the shake; and

a main body controller configured to control the main body shake detector and the main body image blur corrector,

the main body controller electrically connected to the lens controller, and having a selector configured to select either a first combination of the main body image blur corrector and the lens shake detector or a second combination of the lens image blur corrector and the main body shake detector, and a switching part configured to activate one of the first combination or the second combination while deactivating the other of the first combination or the second combination, thereby detecting the shake of the camera system and correcting the image blur produced by the shake.

8. The camera main body according to claim 7 ,

wherein the selector selects the lens image blur corrector when the main body shake detector is selected, and selects the main body image blur corrector when the lens shake detector is selected.

9. The camera main body according to claim 7 ,

wherein the selector selects the lens shake detector when the main body image blur corrector is selected, and selects the main body shake detector when the lens image blur corrector is selected.

10. A camera system for forming an image of a subject, comprising:

a camera main body having an imaging unit configured to form an image of the subject, a main body shake detector configured to detect shake of the camera system, and a main body controller configured to control the imaging unit and the main body shake detector; and

an interchangeable lens arranged to be removably attachable to the camera main body, having a lens shake detector configured to detect the shake, and a lens controller electrically connected to the main body controller and configured to control the lens shake detector,

the camera main body and/or the interchangeable lens further having an image blur corrector configured to correct image blur produced by the shake, and

the main body controller having a selector configured to select either a first combination of the image blur corrector and the lens shake detector when only the camera main body has the image blur corrector or a second combination of the image blur corrector and the main body shake detector when only the interchangeable lens has the image blur corrector, and a switching part configured to activate one of the first combination or the second combination while deactivating the other of the first combination or the second combination, thereby detecting the shake of the camera system and correcting the image blur produced by the shake.

11. A camera system for forming an image of a subject, comprising:

a camera main body, having an imaging unit configured to form an image of the subject, a main body image blur corrector configured to correct image blur produced by shake of the camera system, and a main body controller configured to control the imaging unit and the main body image blur corrector; and

an interchangeable lens arranged to be removably attachable to the camera main body, having a lens image blur corrector configured to correct image blur produced by the shake, and a lens controller electrically connected to the main body controller and configured to control the lens image blur corrector,

the camera main body and/or the interchangeable lens further having a shake detector configured to detect the shake, and

the main body controller having a selector configured to select either a first combination of the shake detector and the lens image blur corrector when only the camera main body has the shake detector or a second combination of the shake detector and the main body image blur corrector when only the interchangeable lens has the shake detector, and a switching part configured to activate one of the first combination or the second combination while deactivating the other of the first combination or the second combination, thereby detecting the shake of the camera system and correcting the image blur produced by the shake.
