PROBLEM TO BE SOLVED: To improve the definition of a picture photographed on the condition of a low illuminance, for example, at night. SOLUTION: Plural still pictures are synthesized by a picture taking-in part 1 which takes in plural continuous still pictures, an outline extraction circuit 10 which extracts outline parts of plural still pictures taken in by the picture taking-in part 1, a feature extraction picture area generation circuit 11 which extracts feature areas from pictures subjected to outline extraction in the outline extraction circuit 10, and a luminance extraction circuit 13 which extracts luminance signal components of still pictures corresponding to areas extracted as feature areas by the feature extraction picture area generation circuit 11. |
