Abstract
A technique that makes it possible to obtain a natural photographed image which does not give a feeling of strangeness and emphasizes differences in brightness between bright stars and low-brightness stars, without depending on a photographic scene. In a case where photographing the starry sky, the number of bright spots is detected from a picked-up image, and image processing performed on the picked-up image is controlled to at least blurring processing or edge emphasis processing or neither the blurring processing nor the edge emphasis processing, according to the number of detected bright spots.
