A still image generation device and a method thereof are provided to service a high-quality still image to a user on the basis of an image formed at the time when capturing a target object. An image sequence storage(310) stores plural consecutive images. An image sequence processing unit(320) extracts the plural consecutive images to generate one still image through image sequence processing on the basis of an image formed at the time when capturing a target object. The plural consecutive images consist of the image formed at the time when capturing the target object and consecutive images before and after the capturing time of the image.
