Zusammenfassung:PROBLEM TO BE SOLVED: To provide a photographing device performing appropriate white balance on respective light sources even if a subject is irradiated with a plurality of the different light sources when a dynamic range is enlarged.SOLUTION: A subject luminance determining unit 33 determines a luminance level of the subject. A dynamic range synthesis determining unit 34 determines whether an image has distribution in bright and dark parts or not from histogram information on a live view image. A light source determining unit 35 determines whether the image includes direct light of the sun and scattering light by reflection or not from a color temperature of the live view image. A photographing control unit 36 controls an image processing unit 14 so that two images are photographed by different exposure and the two photographed images are white balance-processed and synthesized when a mode for performing dynamic range enlargement and multi-white balance composition is set from determining results of the subject luminance determining unit 33, the dynamic range synthesis determining unit 34 and the light source determining unit 35.
