ABSTRACT:
An anti-shake apparatus of a photographing-apparatus includes a movable-unit and a fixed-unit. The movable-unit has an imaging device, and is movable in a first-direction perpendicular to an optical axis of the photographing-apparatus, and performs an anti-shake operation by moving in the first-direction. The fixed-unit slidably supports the movable-unit in the first-direction. The movable-unit has first and second hall-elements for detecting a position of the movable-unit in the first-direction as a first location, in order to calculate a detected-position signal. The fixed-unit has first and second magnets for detecting the first location. The detected-position signal is calculated on the basis of an average of outputs of the first and second hall-elements.
