<p>PURPOSE:To control a proper voltage required for a vibration proofing action by providing a decision level varying means according to the state of a vibration proofing selection means in a source voltage decision means. CONSTITUTION:The check level of a source voltage is set so that it can be changed to VC2 from VC1 according to the state of the selection switch ISSW of the vibration proofing action. When the voltage VC2 for executing the vibration proofing action is selected, feedback control is executed so that the output of an angular displacement sensor (blurring displacement detection means) consisting of an outer jacket 2, liquid 3, a floating body 4 and light receiving and projecting elements 5 and 6 and the angular displacement output of a variable apex angle prism 41 (position detection means) are made equal. Besides, when gain is previously set so that a correction angle per unit angle of the prism 4 and a blurring angle per unit angle of the angular displacement sensor are made equal, the image of an object projected on the image surface of a camera is kept still by the action of a correction optical system even when the camera is moved with respect to absolute space by blurring.</p> |
