1. A photographing device having an image sensor for performing photoelectric conversion of a subject for synthesizing multiple images sequentially acquired by output signals from said image sensor so as to obtain a photography image, said photographing device comprising:

  • a detecting unit for extracting at least one characteristic point in each image of said multiple images and detecting movement of the characteristic point on another image as to a characteristic point on a reference image;

    a coordinate converting unit for performing coordinates conversion of said other image so as to match the characteristic point on said other image with the characteristic point on said reference image based on the detected results of said detecting unit;

    a synthesizing unit for synthesizing said reference image and said other image subjected to coordinates conversion by said coordinate converting unit;

    a determining unit for determining whether or not at least one characteristic point from one of the images acquired by said image sensor prior to photographing can be extracted by said detecting unit; and

    a warning unit for warning a user in the event that said determining unit cannot extract a characteristic point.
