Astronomical imaging apparatus, astronomical imaging method, and program

摘要

PROBLEM TO BE SOLVED: To provide technology capable of restoring an image without deterioration from a deteriorated image by properly acquiring a point spread function representing the influence of blur and out-of-focus during imaging.SOLUTION: An imaging device of the present invention includes first imaging means for imaging a subject and outputting subject image data, second imaging means for imaging a point light source and outputting point image data, and image processing means for generating improved subject image data on the basis of the subject image data and the point image data. The first imaging means and the second imaging means are supported by a common support base to mutually synchronously perform imaging. The subject and the point light source are mounted on a common mounting stand. The image processing means acquires a point spread function on the basis of the point image data to generate improved subject image data on the basis of the point spread function and the subject image data.
