PROBLEM TO BE SOLVED: To provide an imaging system capable of imparting a suitable gray- scale width to a main object in an image regardless of an area and a position of the object. SOLUTION: In an imaging system generating one image with wide dynamic range from more than one image imaged at different exposures, the system comprises an estimation part 14 for main object range to assume a main object range among images from a focus-locked focusing detecting range, a suitable exposure extracting part 13 to extract a suitable exposure range based on the level of an image signal image-by-image among a group of the images, a conversion characteristic calculation part 15 to execute a gray-scale correction to deliver the gray-scale width mainly to the assumed main object range for the extracted suitable exposure range, a brightness corrective part 16, a color- difference corrective part 17, a Y/C combining part 18 and an image combining par 20 to generate one image with wide dynamic range by combining the suitable exposure range of each image executed the gray-scale correction through the parts 15-18.
