  • Patent number: 9759801
    Abstract: A celestial object is automatically tracked and photographed. Azimuth information of the celestial object is obtained relative to a photographic apparatus. First-tracking drive control data for performing a first-tracking photographing operation is calculated based on the azimuth information. The photographing operation is performed during a predetermined exposure time based on the first-tracking drive control data. After the photographing operation finishes, a first image taken in the photographing operation is obtained upon lapse of a predetermined time, and a second image corresponding to an ending of images taken by the photographing operation is obtained. An amount of deviation between a celestial object image in the first image and a corresponding celestial object image in the second image is calculated. A judgement is made as to whether a second-tracking photographing operation is to be performed based on a comparison between the deviation amount and a predetermined threshold.

  • Patent number: 9310459
    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.
