<p>A method of automatically tracking and photographing celestial objects and a celestial-object auto-tracking photographing apparatus are achieved, in which the burden on the CPU can be reduced by eliminating unnecessary arithmetic processes and can clearly photograph a celestial object (s) so as to appear stationary without using an equatorial, which is expensive, large, heavy and requires complicated adjustments, and without using an actuator, which needs to be precisely controlled. A method of automatically tracking and photographing a celestial object, which moves relative to a photographic apparatus due to diurnal motion, in which, in order to photograph the celestial object, a trimming area that has been electronically trimmed from a part of an imaging area of an image sensor is moved while the celestial object is photographed, the method includes obtaining movement information of a celestial-object image on the imaging area; setting movement data for the trimming area based on the obtained the movement information of the celestial-object image; and carrying out a photographing operation while moving the trimming area based on the movement data of the set the trimming area at each trimming area, upon being moved.</p> |
