Abstract:
1. A blur correction apparatus comprising: a blur correcting optical system including at least a part of a photographic optical system, which corrects a blur occurring at an image-capturing surface of a photographing apparatus by moving within a movable range extending along a direction substantially perpendicular to an optical axis of the photographic optical system; a blur correction drive unit that drives the blur correcting optical system; a blur correction operation enabling unit that selects either a blur correction enabled state in which a blur correction operation executed by driving the blur correcting optical system is enabled or a blur correction disabled state in which the blur correction operation is disabled; and a control unit that controls the blur correction drive unit in the blur correction disabled state so as to hold the blur correcting optical system at a specific position in the blur correction disabled state by supplying power during an entire holding period in the blur correction disabled state, and that stops supplying power to the blur correction drive unit in the blur correction disabled state so as to not hold the blur correcting optical system at any specific position, wherein the entire holding period is a period at which the photographing apparatus is subjected to a shock.
