Abstract

An electronic apparatus to which an external apparatus is detachably attachable includes a controlling unit configured to make a vibration device vibrate by using a vibration parameter corresponding to a type of the external apparatus to be attached to the electronic apparatus, the vibration device being provided on at least one of the electronic apparatus and the external apparatus.

First claim

What is claimed is:

1. A camera body to which an external apparatus which is at least one of a lens unit, a strobe unit, a microphone, a viewfinder unit, a tripod, and a jacket is detachably attachable, the camera body comprising:
a vibration device provided on at least one of the camera body and the external apparatus;
a detecting unit configured to output a detection signal indicating that the external apparatus is attached to the camera body;
a vibration detecting unit configured to detect a vibration of the vibration device; and
at least one processor or circuit which functions as a controlling unit configured to make the vibration device vibrate by using a vibration parameter corresponding to a type of the external apparatus to be attached to the camera body,
wherein when the detection signal is acquired, the controlling unit makes the vibration device vibrate by using a vibration parameter corresponding to the type of the external apparatus to be attached to the camera body, the vibration parameter being acquired from management data relating to a vibration parameter of the vibration device,
wherein when the management data does not store the vibration parameter corresponding to the type of the external apparatus to be attached to the camera body, the controlling unit makes the vibration device vibrate by using a vibration parameter corresponding to the type of the external apparatus to be attached to the camera body, the vibration parameter being acquired by performing calibration that causes the vibration device to generate a vibration, and
wherein in the calibration, the controlling unit causes the vibration device to vibrate at a plurality of frequencies and acquires the vibration parameter corresponding to the type of the external apparatus to be attached to the camera body based on a detection result that the vibration detecting unit acquires when the vibration device is caused to vibrate at each of the plurality of frequencies.

2. The camera body according to claim 1 , further comprising a memory unit configured to store the management data,
wherein the controlling unit makes the vibration device vibrate by using a vibration parameter corresponding to the type of the external apparatus to be attached to the camera body, the vibration parameter being acquired from the management data.

3. The camera body according to claim 1 ,
wherein the controlling unit makes the vibration device vibrate by using the vibration parameter corresponding to the type of the external apparatus to be attached to the camera body, the vibration parameter being acquired from the management data that is stored on the external apparatus to be attached to the camera body.

4. The camera body according to claim 1 ,
wherein when a power of the camera body is turned on, the controlling unit makes the vibration device vibrate by using a vibration parameter corresponding to the type of the external apparatus to be attached to the camera body, the vibration parameter being acquired by performing the calibration that causes the vibration device to generate a vibration.

5. The camera body according to claim 1 , further comprising a memory unit configured to store a detection result of the vibration detecting unit,
wherein when a difference is more than a predetermined value between a detection result of the vibration detecting unit for a last vibration of the vibration device and a detection result of the vibration detecting unit for a current vibration of the vibration device, the controlling unit corrects the vibration parameter corresponding to the type of the external apparatus to be attached to the camera body based on the difference.

6. The camera body according to claim 5 ,
wherein the controlling unit periodically makes the vibration device vibrate.

7. The camera body according to claim 1 ,
wherein the vibration detecting unit is capable of detecting a shake of the camera body.

8. The camera body according to claim 1 ,
wherein the vibration device is included in the external apparatus.

9. The camera body according to claim 1 ,
wherein the vibration device is included in the camera body.

10. The camera body according to claim 1 ,
wherein the vibration parameter includes at least one of a vibration frequency, amplitude, and duration.

11. An electronic apparatus to which an external apparatus is detachably attachable comprising:
a vibration detecting unit configured to detect vibrations of a plurality of vibration devices provided on at least one of the electronic apparatus and the external apparatus; and
at least one processor or circuit which functions as a controlling unit configured to make the plurality of vibration devices vibrate by using a vibration parameter corresponding to a type of the external apparatus to be attached to the electronic apparatus, and
wherein the controlling unit controls calibration on vibration parameters for the plurality of vibration devices in order that a vibration amount of the vibration detecting unit is equal to or less than a predetermined threshold.

12. The electronic apparatus according to claim 11 ,
wherein the controlling unit controls the calibration by controlling a phase difference of driving signals of the plurality of vibration devices.

13. An optical apparatus comprising:
an optical element; and
an electronic apparatus according to claim 11 .

14. An image pickup apparatus comprising:
an image sensor configured to convert an optical image of an object into an electrical signal by a photoelectric conversion; and
an electronic apparatus according to claim 11 .

15. A control method of a camera body to which an external apparatus which is at least one of a lens unit, a strobe unit, a microphone, a viewfinder unit, a tripod, and a jacket is detachably attachable, the camera body including a vibration device provided on at least one of the camera body and the external apparatus and a vibration detecting unit configured to detect a vibration of the vibration device, the control method comprising steps of:
acquiring a detection signal indicating that the external apparatus is attached to the camera body;
acquiring a vibration parameter corresponding to a type of the external apparatus to be attached to the camera body; and
making the vibration device vibrate by using the vibration parameter,
wherein when the detection signal is acquired, a vibration parameter corresponding to the type of the external apparatus to be attached to the camera body is acquired from management data relating to a vibration parameter of the vibration device, and the vibration device is made to vibrate,
wherein when the management data does not store the vibration parameter corresponding to the type of the external apparatus to be attached to the camera body, a vibration parameter corresponding to the type of the external apparatus to be attached to the camera body is acquired by calibration that causes the vibration device to generate a vibration, and the vibration device is made to vibrate, and
wherein in the calibration, the vibration device is caused to vibrate at a plurality of frequencies, and the vibration parameter corresponding to the type of the external apparatus to be attached to the camera body is acquired based on a detection result that the vibration detecting unit acquires when the vibration device is caused to vibrate at each of the plurality of frequencies.

16. A non-transitory computer-readable storage medium storing a computer program that causes a computer to execute the control method according to claim 15 .
