1. An image capturing apparatus comprising: an image sensor in which a plurality of pixels are arrayed two-dimensionally; a driving unit that bends the image sensor; and a control unit that controls the driving unit to bend the image sensor at a predetermined curvature, wherein the control unit controls the driving unit so that stress acting on the image sensor in the case where an image capture operation is not carried out is lower than stress acting on the image sensor in the case where an image capture operation is carried out.
