<P>PROBLEM TO BE SOLVED: To solve the problem that it is difficult in the conventional imaging device to image a whole emerging shooting star from its emergence with light to its extinction within one picture. <P>SOLUTION: A PC 4 obtains a direction of a shooting star 12 to be seen from a position at which a camera 1 presents and a sky range from which the lighting shooting star 12 emerges, by calculation based on orbital information of the shooting star 12 acquired by shooting star information acquisition means. View angle setting means sets a view angle of the camera 1 in S5 so that the view angle of the camera 1 matches the sky range obtained by the PC 4. A CPU of the camera 1 acquires a shooting star image in S8 by making imaging means image the shooting star 12 by using an imaging direction driven by a drive part 2 and the view angle set by the view angle setting means. Thereby, the view angle of the camera 1 is set to the view angle matching the sky range from which the lighting shooting star 12 emerges, to easily image the whole shooting star 12 emerging with light within one picture. <P>COPYRIGHT: (C)2012,JPO&INPIT |
