An image blurring correction device includes a correction member which moves in a direction perpendicular to the optical axis of an imaging optical system to correct blurring of an optical image, two driving units which drive the correction member in different directions, a shake detection unit which detects a shake applied to the image blurring correction device, a correction amount calculation unit which calculates, based on shake information detected by the shake detection unit, a correction amount for correcting blurring of the optical image, and a conversion unit which converts the correction amount to cancel a driving error generated by a rotation moment applied to the correction member. The driving units drive the correction member based on the correction amount converted by the conversion unit, correcting blurring of the optical image.
