摘要

An image blur correction apparatus includes a vibration detection unit configured to detect vibration information of the image blur correction apparatus to output a vibration signal, a signal separation unit configured to separate the vibration signal into a first vibration signal and a second vibration signal, a first sensitivity correction unit configured to correct an amplitude of the first vibration signal, a second sensitivity correction unit configured to correct an amplitude of the second vibration signal, a first drive unit configured to drive the first optical correction unit based on an output signal from the first sensitivity correction unit, and a second drive unit configured to drive the second optical correction unit based on an output signal from the second sensitivity correction unit.
