发明名称 OPTICAL APPARATUS
摘要 The invention relates to an optical apparatus having a vibration detector that detects vibration, a holding member that holds an image stabilizing optical system, an elastic member that elastically supports the holding member so that the holding member can shift within a plane perpendicular to an optical axis, a drive unit that generates a drive force resisting against an elastic force of the elastic member, a drive circuit that drives the drive unit, a control circuit that controls the position of the holding member, a temperature sensor that measures temperature, and a viscous damper that damps movement of the holding member in the drive direction. The control circuit changes the image stabilizing drive control characteristic of the drive circuit to compensate for changes in viscosity of the viscous damper with temperature.
