发明名称 Image blur correction apparatus
摘要 In this invention, an image blur correction apparatus adapted to an optical apparatus, which has an image blur correction means, a driving means for driving the image blur correction means in a predetermined direction, and an energization control means for controlling energization to the driving means in accordance with a vibration signal corresponding to the vibration state of the optical apparatus, also has an energization restricting means for restricting a current supplied to the driving means by the energization control means to less than a predetermined restricting level, and a determination means for determining the restricting level of the energization restricting means in accordance with the detection result of a gravitation direction detection means for detecting the gravitation direction, whereby the upper limit of the energization amount to the driving means is changed in accordance with the gravitation direction to attain driving suitable for the direction of gravitation acting on the apparatus.
