PROBLEM TO BE SOLVED: To obtain a high-quality high-dynamic range image by one photographing.SOLUTION: Preparatory imaging data is obtained in a color imaging device part 102 comprising a CMOS sensor by executing preparatory imaging of a subject. A bright/dark region map resulting from setting each pixel of the sensor to a bright or dark region is generated on the basis of the preparatory imaging data by a pixel bright/dark region map generation part 505, and boundary parts between bright regions and dark regions in the bright/dark region map are detected by a contour detection part 506, and such correction is performed by a contour correction part 507 that dark region pixels in the boundary parts become bright region pixels, and thus an exposure time map is generated. A driving pulse for each pixel of the sensor is generated in a timing generator part 507 in accordance with the exposure time map, whereby the subject is actually imaged. |
