PROBLEM TO BE SOLVED: To solve the problem in which an image device is required to sufficiently secure a tremor-proof range during an exposure, and execute a stable tremor-proof even when a panning operation or large tremor occurs upon through-imaging.SOLUTION: An image tremor correction device includes an image pick-up element converting a subject image formed by a photographing optical system into an electric signal and first and second optical correction means causing a relative position of the image pickup element with respect to the subject image to vary in an imaging-plane, and the problem is solved by the image tremor correction device that comprises: tremor detection means for detecting a tremor applied to the image tremor correction device; target position calculation means for calculating respective target positions of the first and second optical correction means in accordance with the tremor detected by the tremor detection means; current position detection means for detecting a current position of the first and second optical correction means; and feedback control means for performing a feedback control so that respective current positions detected by the current position detection means converge to the target position calculated by the target position calculation means. |
