<p>PURPOSE:To prevent the influence of vignetting from carelessly being made large by providing an aperture control means which controls the aperture of the vibration-proof camera according to the relation between information on the photographic state of the camera and the operation state of a vibration- proofing device. CONSTITUTION:Aperture information from an aperture information output means 12 is inputted to a display means 13 and a limiting means 11. This aperture information is a larger and larger output as the aperture is smaller and smaller and the limit level of a limiting means 11 varies according to the output. Then, the limiting means 11 has a function which cuts a large-amplitude part, shown by 14b, of the hand shake output 14a of a vibration detecting means 14 during operation, and the extent of cutting is larger and larger as the aperture is smaller and smaller. A driving means 15 faithfully drives a correction optical means by using the signal of the handshake output 14b after the large amplitude is cut as a command signal. The correction optical means is therefore not driven with the large amplitude and the influence of vignetting is made small.</p> |
