Abstract
An imaging apparatus includes an imaging unit configured to image an image within a first range on an imaging surface, a first correction unit configured to optically compensate for image shake on the image surface resulting from shake of a device, a second correction unit configured to electronically correct image shake on the image surface resulting from shake of the imaging apparatus, and output an image from a second range that is narrower than the first range, and a control unit configured to determine the moveable range of the first correction unit. The control unit performs control to increase the moveable range of the first correction unit when the second correction unit is used in comparison to when the second correction unit is not used.
Claims10
An imaging apparatus comprising:
- an imaging unit configured to capture an image within a first range on an imaging surface;
- a first correction unit configured to optically correct for image shake on the image surface resulting from shake of the imaging apparatus;
- a second correction unit configured to electronically correct image shake on the image surface resulting from shake of the imaging apparatus, and output an image from a second range that is narrower than the first range;
- and
- a control unit configured to determine a moveable amount of the first correction unit,
- wherein the control unit performs control to increase the moveable amount of the first correction unit when second correction unit is performed in comparison to when the second correction unit is not performed.
An optical apparatus that is mounted on an imaging apparatus provided with a correction unit configured to electronically correct image shake resulting from shake of the apparatus, the optical apparatus comprising:
- an image stabilization unit configured to optically correct image shake on an image surface resulting from shake of the apparatus;
- a receiving unit configured to receive, from the imaging apparatus, information indicating whether the correction unit provided in the imaging apparatus is performed;
- and
- a control unit configured to determine a moveable amount of the image stabilization unit,
- wherein the control unit performs control to increase the moveable amount of the image stabilization unit when the information indicates that the correction unit is performed in comparison to when the information indicates that the correction unit is not performed.
An imaging system comprising:
- an optical apparatus comprising:
- an image stabilization unit configured to optically correct for image shake on an image surface resulting from shake of the apparatus;
- and
- a control unit configured to determine a moveable amount of the image stabilization unit;
- and
- an imaging apparatus comprising:
- an imaging unit configured to capture an image within a first range on the imaging surface;
- a correction unit configured to electronically correct image shake on the image surface resulting from shake of the apparatus, and output an image from a second range that is narrower than the first range, and
- wherein the control unit performs control to increase the moveable amount of the image stabilization unit when the correction unit is performed in comparison to when the correction unit is not performed.
A method for controlling an imaging apparatus, the method comprising:
- capturing an image within a first range on an imaging surface;
- optically correcting, by a first correction unit, for image shake on the image surface resulting from shake of the imaging apparatus;
- electronically correcting, by a second correction unit, image shake on the image surface resulting from shake of the imaging apparatus, and outputting an image from a second range that is narrower than the first range;
- and
- determining a moveable amount of the first correction unit,
- wherein, in the determining step, control is performed to increase the moveable amount of the first correction unit when the second correction unit is performed in comparison to when the second correction unit is not performed.
A method for controlling an optical apparatus that is mounted on an imaging apparatus provided with a correction unit configured to electronically correct image shake resulting from shake of the apparatus, the method comprising:
- optically correcting, by an image stabilization unit, image shake on an image surface resulting from shake of the apparatus;
- receiving, from the imaging apparatus, information indicating whether the correction unit provided in the imaging apparatus is performed;
- and
- determining a moveable amount of the image stabilization unit,
- wherein, in the determining step, control is performed to increase the moveable amount of the image stabilization unit when the information indicates that the correction unit is performed in comparison to when the information indicates that the correction unit is not performed.
