IMAGE-BLUR CORRECTION DEVICE, IMAGE-BLUR CORRECTION METHOD, AND IMAGE CAPTURE APPARATUS

摘要

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.
