Patent number: 8212860Abstract: A digital camera having an image mover includes a controller, a location information inputter, an orientation information inputter, a focal length information inputter, and an exposure time setter which sets an exposure time for which a celestial body image is exposed to an image sensor. The controller calculates a movement path of the celestial body image, which moves relative to the photographing optical system due to the rotation of the earth within the exposure time, using the location information that is input to the controller via the location information inputter, and the azimuth information and the altitude information that are input to the controller via the orientation information inputter. The controller drives the image mover in accordance with the calculated movement path to move the image sensor in a manner such that the image of the celestial body remains at a stationary position on the image sensor.Type: GrantFiled: October 22, 2009Date of Patent: July 3, 2012Assignee: Pentax Ricoh Imaging Company, Ltd.Inventor: Norio Numako
