<p>PURPOSE:To obtain an optical jiggle detection device which can detect the blurring of an object image caused by jiggle even in the midst of exposure. CONSTITUTION:An image formation optical system 4 which forms the image of an object on an image sensor 5 is provided as an object image detection means in addition to an image formation optical system by a photographing lens 2. The optical system 4 is constituted by being built in a camera main body 1 or an interchangeable photographing lens or utilizing a finder optical system or an external optical system range-finding means. Besides, a varying means by the switching of a zoom lens system which changes the focal distance of the image formation optical system according to the change of the focal distance by the photographing lens or plural lens systems whose focal distances are different is selectively installed. Moreover, a jiggle arithmetic device 6 is provided as a jiggle detection means which detects the jiggle of a camera based on the temporal change of a pattern outputted by the image sensor is provided.</p> |
