An image having the image quality desired by a photographer is provided by minimizing overexposure or underexposure, making the dynamic range wide, and specifying an optimum brightness level for a main subject. An image capturing device includes a subject detecting unit which detects a main subject in an image obtained before actual photographing; a subject luminance information acquiring unit which obtains luminance information; a luminance distribution calculating unit which calculates a luminance distribution of each of multiple areas; a target luminance calculating unit which determines a target luminance; a target luminance correcting unit which corrects the target luminance; and an exposure condition determining unit which determines an exposure condition for the actual photographing, in which the target luminance correcting unit includes a criterial range determining unit which determines the criterial range; and a correction amount determining unit which determines a correction amount by using the difference between the target luminance and the luminance of the main subject.
