Abstract
Official abstract text for this publication.
An image capturing apparatus includes an image sensor, an optical system that forms a subject image on an image sensing plane of the image sensor, a driving unit that curves the image sensor, and a control unit that controls the driving unit to curve the image sensor to a curvature according to aberration of the optical system and image capturing conditions.
First claim
Opening claim text (preview).
What is claimed is: 1 . An image capturing apparatus comprising: an image sensor; an optical system configured to form a subject image on an image sensing plane of the image sensor; a driving unit configured to curve the image sensor; and a control unit configured to control the driving unit to curve the image sensor to a curvature according to aberration of the optical system and image capturing conditions. 2 . The image capturing apparatus according to claim 1 , wherein the image sensor has a characteristic in which dark current noise varies according to the curvature. 3 . The image capturing apparatus according to claim 2 , wherein the control unit controls the driving unit to curve the image sensor to a curvature at which the dark current noise in the image sensor decreases. 4 . The image capturing apparatus according to claim 1 , wherein the driving unit curves at least the image sensing plane of the image sensor. 5 . The image capturing apparatus according to claim 1 , wherein the aberration of the optical system includes a curvature of field aberration. 6 . The image capturing apparatus according to claim 1 , wherein the image capturing conditions include sensitivity. 7 . The image capturing apparatus according to claim 1 , wherein the image capturing conditions include exposure time of the image sensor. 8 . The image capturing apparatus according to claim 1 , wherein the image capturing conditions include temperature at image capture. 9 . The image capturing apparatus according to claim 1 , wherein the image capturing conditions include aperture value. 10 . The image capturing apparatus according to claim 1 , wherein the control unit, in a case where a region that is to be focused on in the optical system is outside of a predetermined range of the image sensing plane of the image sensor, controls the driving unit to curve the image sensor to a curvature that prioritizes correction of the aberration of the optical system. 11 . The image capturing apparatus according to claim 1 , wherein the control unit, in a case where a subject that is to be focused on in the optical system is outside of a predetermined range of the image sensing plane of the image sensor, controls the driving unit to curve the image sensor to a curvature that prioritizes correction of the aberration of the optical system. 12 . The image capturing apparatus according to claim 1 , wherein the driving unit curves the image sensor by using magnetic force. 13 . A method of controlling an image capturing apparatus that includes an image sensor, an optical system configured to form a subject image on an image sensing plane of the image sensor, and a driving unit configured to curve the image sensor, the method comprising: controlling the driving unit to curve the image sensor to a curvature according to aberration of the optical system and image capturing conditions.
