Abstract:
An image fluctuation correction device includes a shake detecting means 5 for detecting a shake occurring in a photographic device, two movable refraction elements 10A, 10B arranged on an incident light path to an optical lens 3 to change a direction of refraction of incident light on the optic lens, two rotating means 4A, 4B for rotating each of the two movable refraction elements 10A, 10B about an optical axis within a predetermined movable range, a rotating control amount calculating means 6A for calculating rotating control amounts of the two rotating means 4A, 4B so as to cancel the shake detected by the shake detecting means, and rotating control means 6B for controlling the two rotating means 4A, 4B on the basis of the rotating control amounts calculated by the rotating control amount calculating means 6A.
