| 摘要 |
An imaging device includes an image stabilizer which detects vibration applied to a photographing optical system and moves at least one optical element of the photographing optical system in a plane orthogonal to a common optical axis of the photographing optical system to counteract image shake in accordance with a direction and a magnitude of the vibration; and a radially-retracting device which moves the optical element between a photographing position, at which the optical element is located on the common optical axis in a photographic state, and a radially-retracted position, at which the optical element is radially retracted away from the common optical axis in a non-photographing state.
