An image-blur correction device includes a drive-current output unit that outputs a first drive current for driving a first correction mechanism for correcting image blur in a first direction orthogonal to an optical axis and a second drive current for driving a second correction mechanism for correcting image blur in a second direction orthogonal to the optical axis and the first direction; and a drive-current limiting unit that limits the first drive current to a first limit value, limits the second drive current to a second limit value, limits a total value of the first and second drive currents to a third limit value smaller than a total value of the first and second limit values, varies the first limit value by changing a power-supply time of the first drive current, and varies the second limit value by changing a power-supply time of the second drive current.

Image-blur correction device, image-blur correction method, and image capture apparatus

A lens unitincluding an imaging optical systemand an imaging unitto generate an image signal of an imaged image is supported rotatably in a yawing direction and in a pitching direction. Based on a shake which is applied to the lens unitand is detected by a shake detection unit, a barycentric position of the lens unitwhich position is calculated by a barycentric position calculation unit, and a position of the lens unitwhich position is detected by a position detection unit, a driving operation by a drive unitto perform rotation driving of the lens unitin the yawing direction and in the pitching direction is controlled and image blur correction of the imaged image is performed. Even when the barycentric position of the lens unit varies due to a focus adjusting operation, a zooming operation, or the like, it becomes possible to perform optimal image blur correction and to improve performance in image blur correction.

Image blur correction apparatus, method of correcting image blur, and imaging apparatus

Provided is an image blur correction apparatus including a lens unit having an imaging optical system and an imaging unit configured to generate an image signal of a captured image, a blur detection unit configured to detect blurring occurring in the lens unit, a first correction unit configured to perform image blur correction by turning the lens unit in a first direction and in a second direction, a second correction unit configured to perform image blur correction on a captured image obtained by the imaging optical system, and an image blur correction control unit configured to drive the first correction unit and the second correction unit based on blurring detected by the blur detection unit.

Image blur correction apparatus, image blur correction method, and imaging apparatus

A blur correcting device includes a shake detecting unit configured to detect a shake and output a detection signal indicating a result of the detection; a drive unit configured to displace a relative positional relationship between a lens unit and an image pickup element relative to an optical axis such that a position of an optical image formed on an image pickup surface of the image pickup element is displaced on the image pickup surface; and a control unit configured to increase a displacement range when the amount of shake indicated by the detection signal is larger than a predetermined level, displace the relative positional relationship between the lens unit and the image pickup element within the increased displacement range in accordance with the detection signal, and thereby correct a blur of the optical image on the image pickup surface caused by the shake detected by the shake detecting unit.
