Abstract:
1. An image stabilization apparatus comprising: a housing accommodating an optical system in the interior thereof; holding means for holding a part of optical members that compose said optical system in such a way as to allow angular displacement of said part of the optical members relative to said housing, in order to maintain the position of said part of the optical members in a predetermined state; driving means for angularly displacing said part of the optical members in the direction for restoring the position of said part of the optical members that has been angularly displaced; control means for controlling said driving means, said control means including detection means for detecting information on angular displacement of said part of the optical members and determination means for determining, based on the information detected by said detection means, a control mode for controlling said driving means and suitable for vibration applied to said housing; a vibration reduction on/off button; and a mode setting dial by which a vibration reduction mode differing in control mode is selectable and by which can be set, a SHIFT Position mode in which, upon depression of the vibration reduction on/off button, a vibration reduction mode set prior to the depression of vibration reduction on/off button is switched over to a vibration reduction mode differing therefrom.
