<P>PROBLEM TO BE SOLVED: To reduce random noise generated in a wide dynamic range image. <P>SOLUTION: A main processing composition unit 39 combines three images which are a short-time exposure image, a normal exposure image, and a long-time exposure image generated by imaging an identical subject by an imaging element with different exposure amounts to generate one wide dynamic range image. If a sensitivity determination unit 35 determines, in photographing, that the sensitivity of the imaging element is low sensitivity lower than a threshold, a pre-processing composition unit 38 combines plural images generated through plural times of imaging with an exposure amount smaller than that of normal exposure to generate one image for noise reduction, and then outputs the image for noise reduction to the main processing composition unit 39 as the short-time exposure image. <P>COPYRIGHT: (C)2013,JPO&INPIT |
