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

An image capture apparatus comprising:

• an image capture unit configured to generate an image signal of a captured image;
• a shake detecting unit configured to detect shake of the image capture apparatus;
• a first correction mechanism configured to correct, in the captured image, image blur in a first direction orthogonal to an optical axis;
• a second correction mechanism configured to correct, in the captured image, image blur in a second direction orthogonal to the optical axis and the first direction;
• a drive-current output unit configured to output a first drive current for driving the first correction mechanism and a second drive current for driving the second correction mechanism;
• and
• a drive-current limiting unit configured to limit the first drive current to a first limit value, limit the second drive current to a second limit value, and limit a total value of the first drive current and the second drive current to a third limit value that is smaller than a total value of the first limit value and the second limit value, in accordance with a detection result of the image blur, and to vary the first limit value by changing a power-supply time of the first drive current and vary the second limit value by changing a power-supply time of the second drive current.
