Abstract
Automatically tracking and photographing celestial objects and a celestial-object auto-tracking photographing apparatus, in which the burden on the CPU can be reduced by eliminating unnecessary arithmetic processes and can clearly photograph an object(s) so as to appear stationary without using an equatorial, and without using an actuator, which must be precisely controlled. The method includes moving relative to a photographic apparatus due to diurnal motion, to photograph a trimming area that has been electronically trimmed from a part of an imaging area of an image sensor, moving while the celestial object is photographed, including obtaining movement information of an image on the imaging area; setting movement data for the trimming area based on the obtained movement information of the image; and carrying out a photographing operation while moving the trimming area based on the movement data of the set trimming area at each trimming area, upon being moved.
