To perform a plurality of photography operations of a single subject under different photography conditions to obtain a plurality of image data sets corresponding to each photography operation, then process the image data to obtain a single dynamic range expanded image data set, without the dynamic range being limited by hardware specifications. A photography method is selected from among: a first method, in which photography is performed at least twice at different exposures; a second method, in which photography is performed with an underexposure at a step number based on a set dynamic range; and a third method, in which photography is performed at least twice with different underexposures at step numbers based on a set dynamic range, based on whether photography operations are possible at exposure ratios, corresponding to the expansion rate of the dynamic range and whether flash is emitted. Photography is performed according to the selected method. |
