<p>PURPOSE:To reduce cost by miniaturizing the device and reducing parts and an assembly stage. CONSTITUTION:This device is provided with apex angle detection means 9P, 9Y to 11P and 11Y arranged in the vicinity of the central plane of a variable apex angle prism 1 whose one surface is held to freely rock to a fixed member 6 and detecting the apex angle of the prism 1 in a two-dimensional direction, and a control means controlling at least two or more driving means 8P and 8Y based on the apex angle signal obtained from the apex angle detection means and a deflection signal obtained from a deflection detection means. Then, image blurring is corrected only by driving one surface of the prism 1.</p> |
