Abstract:
1. An image capturing device comprising: a subject detecting unit which detects a main subject in an image obtained before actual photographing, from an image signal of the image; a subject luminance information acquiring unit which obtains luminance information on the main subject from the image signal; a luminance distribution calculating unit which calculates a luminance distribution of each of multiple areas in the image; a target luminance calculating unit which determines a target luminance, related to exposure, based on the luminance distribution; a target luminance correcting unit which corrects the target luminance when a difference between the target luminance and the luminance of the main subject does not fall in a criterial range; and an exposure condition determining unit which determines an exposure condition for the actual photographing based on the target luminance or a corrected target luminance when the target luminance correcting unit has corrected the target luminance, wherein the target luminance correcting unit comprises: wherein the image capturing device has a first setting mode in which a local gradation conversion process is applied to a pixel of interest of the image based on the image signal of a local area around the pixel of interest, and a second setting mode in which the local gradation conversion process is not applied, and wherein the criterial range determining unit determines the criterial range according to a setting mode that is used.
