Image stabilization apparatus, control method therefor, optical apparatus and image capturing apparatus |
摘要 |
An image stabilization apparatus comprises: an image stabilization unit that reduces image blur due to a shake by moving a driven unit; a calculation unit that estimates the shake based on a position of the driven unit and a driving force applied to the driven unit and that calculates a translational shake correction amount based on the estimated shake; and a driving unit that drives the driven unit of the image stabilization unit based on the translational shake correction amount. When the driven unit is at a position away from a center of a range of movement of the driven unit, the calculation unit sets the translational shake correction amount to be smaller than that when the driven unit is at the center of the range of movement. |

1. An image stabilization apparatus comprising:
an image stabilization unit that reduces image blur due to a shake by moving a driven unit; a calculation unit that estimates the shake based on a position of the driven unit and a driving force applied to the driven unit and that calculates a translational shake correction amount based on the estimated shake; and a driving unit that drives the driven unit of the image stabilization unit based on the translational shake correction amount, wherein when the driven unit is at a position away from a center of a range of movement of the driven unit, the calculation unit sets the translational shake correction amount to be smaller than that when the driven unit is at the center of the range of movement. |
