Abstract:
1. A digital camera equipped with an image mover which moves an object image formed via a photographing optical system in a predetermined path in a plane orthogonal to an optical axis of said photographing optical system, said digital camera comprising: a controller; a location information inputter via which location information on said digital camera is input to said controller; an orientation information inputter via which azimuth information and altitude information are input to said controller; a focal length information inputter via which focal length information on said photographing optical system is input to said controller; and an exposure time setter which sets an exposure time for which an image of a celestial body formed through said photographing optical system is exposed to an image sensor, wherein said controller calculates a movement path of said image of said celestial body, which moves relative to an initial position of an image circle of said photographing optical system due to the rotation of the earth within said exposure time, using said location information, said azimuth information and said altitude information that are input to said controller, and wherein said controller drives said image mover in accordance with said calculated movement path to move said image in a manner such that said image of said celestial body remains at a stationary position on said image sensor.
