    • There is provided a shake correction apparatus having an image pickup optical system that includes a correction lens capable of moving in a direction orthogonal to an optical axis. The shake correction apparatus comprises: a detection unit that detects shake applied to the shake correction apparatus; a determination unit that determines a reference position of the correction lens; and a drive unit that drives the correction lens with the reference position serving as a center position, so as to correct the shake detected by the detection unit. The determination unit determines the reference position, in a range where a condition that a Modulation Transfer Function (MTF) of the image pickup optical system when the correction lens is positioned at the determined reference position is equal to or larger than a threshold is satisfied.
    • 提供一种具有摄像光学系统的抖动校正装置,该摄像光学系统包括能够在与光轴正交的方向上移动的校正透镜。 抖动校正装置包括:检测单元,其检测施加到抖动校正装置的抖动; 确定单元,确定校正透镜的基准位置; 以及驱动单元,其以参考位置驱动所述校正透镜作为中心位置,以便校正由所述检测单元检测到的抖动。 确定单元确定在校正透镜位于所确定的基准位置处的摄像光学系统的调制传递函数(MTF)等于或大于阈值的条件的范围内的基准位置。
