PURPOSE:To prevent image blurring due to a camera shake of the camera by providing optical fiber loops to the lens barrel or camera body of the camera. CONSTITUTION:The optical fiber loops 11a and 11b are provided in a surface curved in conformity with the curvature of the lens barrel 12 and a longitudinal and a lateral shake of the camera are detected through the loops 11a and 11b. Namely, the loops 11a and 11b have their winding center lines 13a and 13b at right angles to a longitudinal and a lateral shake vibration plane. Then light beam propagated in the loops 11a and 11b are inputted to detectors 45a and 45b respectively to detect variation in the intensity of interference light, and the variation is integrated and amplified by an analog integrator and outputted to driving parts 47a and 47b of a correction optical systems 46. Thus, the image blurring due to a camera shake of the camera can be prevented. |
